Technical guide Neutral plans

Medium Voltage Neutral PlanThere are a number of techniques in use across the world for the type of neutral plan used in Medium Voltage networks.Indeed, each country has chosen its own solution, its own settings, depending on its network, its choices and requirements in terms of quality and its network operating methods.Moreover, a distinction should be made between 4-wire distribution networks (North American system) and the 3-wire distribution networks (European system).

6 types of neutral planTuned neutral: Eastern Europe.Neutral earthed directly without a 4th conductor: United Kingdom.Neutral earthed directly with a 4th conductor: North America, Australia, Saudi Arabia, and South Africa.Neutral earthed via an impedance: North Africa, Spain, Malaysia, Indonesia, some countries in South America.Tuned neutral earthed via an impedance: France.Neutral insulated from earth: Japan, Ireland, Italy, and Russia.

The impact of the neutral planThe choice of neutral plan impacts, not only upon the size of the equipment and the couplings between power transformers, but also on the safety of personnel and continuity of service.

Technical guide Neutral plans

Principal types and advantages

Neutral earthed directly with a 4th conductor:■ Excellent at controlling overvoltages.■ Diffi culties in detecting earth faults (a fault is equivalent to a load, because the load is also

measured between phase and earth).■ Mediocre service quality: Numerous voltage drops following each earthing fault, but few interruptions impacting upon the whole Medium Voltage outgoing feeder thanks to the various pieces of protective equipment (fuses, re-closers, isolating switches, etc.).■ Very high fault-to-earth currents (several kA).■ Phase to earth network isolation close to the phase-to-neutral voltage.■ Protection system based on inverse time ammetric relays and fuses: Co-ordination of protective equipment highly complex.■ Reduced manufacturing costs.■ Well adapted to areas with a low population density.■ Under extreme conditions: SWER (Single Wire Earth Return) Australia.

Neutral earthed directly without a 4th conductor:■ Solution different from the “North American” system.■ No distributed neutral.■ Fault currents limited by zero-phase sequence impedance of the transformer.■ Voltage increases diffi cult to control.■ Highly effi cient protective equipment.■ Very high fault current (several thousand amperes).■ No need for a network with phase to earth isolation resistant to phase-to-phase voltages.

Neutral insulated from earth■ Service voltage generally not very high (rarely more than 10 or 11 kV between phases).■ Short networks (Low residual capacitive currents).■ Good control of overvoltages on short, overhead line networks.■ Relatively average protection effi ciency.■ Relatively average power supply quality.■ Little current circulating during an earth fault (only due to network phase-to-earth capacities).■ Phase to earth isolation of the network at line voltage.■ Diffi cult to detect and localize faults.■ Risk of overvoltages.

Earthing by compensation reactance■ Control of the fault current if the network does not have any large zero-phase sequence capacities (few underground cables)■ Average at controlling overvoltages.■ Simple, sensitive and economical protection system.■ Quality of service more or less good depending on the fault elimination and protection systems (circuit-breaker, shunt, etc.).■ Fault current more or less weak, but relatively well controlled.■ Operational fl exibility.■ The need for a network with phase to earth isolation resistant to phase-to-phase voltages.

Neutral earthed by impedance■ Virtually total control over fault currents.■ Control over overvoltages good to excellent.■ Average detection sensitivity for earth faults.■ Good supply quality, especially if the fault is constant.■ The need for a network with phase to earth isolation resistant to phase-to-phase voltages.


Introduction Presentation

Use of the FluokitFluokit is the latest generation of air-isolated switchgear from Schneider Electric. It is a modular switchboard fi tted with gas-insulated (SF6) switch-disconnector and earthing switches.To protect the transformer, it can also be equipped with:■ An SF6-insulated switch-disconnector with fuse combination.■ A disconnectable or withdrawable SF6 circuit-breaker.■ A disconnectable vacuum circuit-breaker.Its modular design and variety of functions make the Fluokit the ideal switchboard for many different applications, including public distribution, industry, infrastructure or wind farms.

Easy to install and useThe installation and operations of Fluokit switchboards are made easy by:■ The reduced dimensions of each cubicle.■ A user-friendly, simple man-machine interface, reproducing the single-line diagram indicating the exact location of the switches.■ Push-button direct control for the switch-disconnector.■ Access via the front of the cubicle.■ Can be connected to all existing equipment and of a similar construction (addition of base unit, top box or even ducting).Continuity of service

Fluokit has LSC2A classifi cation as per IEC 62271-200, giving it the following advantages:■ Low maintenance-fi tted with a sealed-unit switch-disconnector.■ Operating mechanism can be replaced without interrupting service.■ Functions can be individually earthed without impact on the rest of the switchboard.

Improved personnel safetyDesigned with safety in mind, Fluokit is one of the safest medium voltage switchboards on the market today:■ Internal arc resistant as per IEC standards: AFL up to 20 kA – 1 s ; AF up to 25 kA – 1 s.■ Hot gas exhaust valves at the rear of the cubicle, protecting the operator in the event of an internal fault.■ Completely metallic outer casing, permanently earthed.■ Clearly displayed switch-disconnector position and fuse status.■ Earthing switch with making capacity and a visible indication of its position via inspection windows in the cable compartment doors.■ Mechanical interlocks stopping access to the cable compartment when the earthing switch is open.■ Full range of key and padlock-based locking devices.

Operating Interlockings

Interlocking of the functional unitsDuring the development of the Fluokit switchboard, the accent was placed on personnel safety and the reliability of the operation.A locking system prevents any incorrect use.Thus, the operating levers can only be inserted if the service status permits it.

Access to the cables compartment and to the fuses is only possible if the appropriate outgoing feeder is connected to earth.

These switchboards are fi tted, as standard, with the following locks and conform to the recommendations of IEC 62271-200:

Operating mechanisms for ISR switch-disconnector

Operating principleThe operating mechanisms used are stored-energy type.The energy required to operate them is stored in a compressed spring.The manoeuvre, independent of operator involvement, takes place once a dead-point is reached, either by pressing a local button, activating an electro-magnet or a fuse striker actuating a latch.

NOTE: The operating mechanisms include both the opening and closing mechanisms for earthing switches. Closure is independent of an operator.

The positions of the earthing switch are always visible through the inspection ports on the front of the cubicle.IMPORTANT: All operating mechanisms are interchangeable. A mechanism change can be carried out with the switch-disconnector energised.

Type Operating Principles Use

C 410XS*C 410C 410SCD 10CD 10SCCD 10SB

'Dead-point' mechanisms The load-break or earthing switch mechanism is operated manually by the operator. The change in state is independent of the operator.

* Mechanism fi tted to certain earthing switches.

Standard equipment on incoming and outgoing feeders

C 410MCD 10M

Motorised mechanism. The change of state is controlled by a motor, without duration or time delay constraints (operating time <7 seconds).

Remotely controlling a switch

C 430 Tripping point mechanism for closure and latch for opening The operator arms the mechanism, closing the circuit. This is then ready for a rapid (<100 ms) opening, triggered by an electro-magnet, fuse striker or local pushbutton control.

- Tripping of a switch on blowing of one or more fuses (protecting a load using combined fuses).- Tripping of a switch-disconnector by the action of a transformer protection relay- Opening of a switch-disconnector during a voltage drop.

C 430 M C 430 Motorised mechanism The closing operation is controlled by a motor (<10 seconds)

Remotely controlling a fused-switch

C 440 Latched open and closed mechanism The operator manually changes the armed status of the mechanism, storing suffi cient energy to carry out two status change operations (closure and opening) without further intentional delay in a short time (<100 ms), opening triggered by electro-magnets, local push buttons or a fuse striker.

All network operations and blown fuse triggering where a short C/O cycle is required.

C 440 M C 440 Motorised mechanism The arming operation is controlled by a motor (<10 seconds)

All cases as above where, in addition to the C/O cycle, complete automation is required.

Operating diagram



Operating mechanisms for orthofl uor fp circuit-breakers ORTHOFLUOR FPThese operating mechanisms use the energy stored by springs to close and open the circuit-breaker. There are two types:

■ BLR: BLR: The operator manually executes a manoeuvre to prime the control mechanism’s spring. The spring is held in place by a latch, freed manually by a mechanical button, causing:□ The release of the spring,□ The closing of the CB,□ The arming of the trip spring, which is then held in place by a latch.It is thus possible to open the circuit-breaker by freeing the trip spring latch manually (mechanical button) or electrically (electro-magnet).Note: With the circuit-breaker closed it is possible to rearm the closing spring, which authorises a rapid re-closure cycle.

■ BLRM: A motorised BLR mechanism.The closing spring is armed by a motor (arming time <15 s). The closure and opening are carried out electrically (electro-magnets).Note: It is possible to manually arm, close and trip the circuit-breakers.

VEIVacuum L circuit-breaker operating mechanismsThese operating mechanisms use the energy stored by springs to close and open the circuit-breaker. There are two types:

■ Manual: The operator manually executes a manoeuvre to prime the control mechanism’s spring. The spring is held in place by a latch, freed manually by a mechanical button, causing:□ The release of the spring,□ The closing of the circuit-breaker.□ The arming of the trip spring, now held in place by a latch.It is thus possible to open the circuit-breaker by freeing the trip spring latch manually (mechanical button) or electrically (electro-magnet).Note: With the circuit-breaker closed it is possible to rearm the closing spring, which authorises a rapid re-closure cycle.

■ Motorised: The closing spring is armed by a motor (arming time <15s). Opening and closure operations are carried out electrically (electro-magnets).Note: - It is possible to manually arm, close and trip the circuit-breakers.

Technical characteristics Fuses compartment

PF cubicleThe PF cubicle with HV fuse protection blows the fuse on detection of a fault current without opening the switch-disconnector.The other phases thus remain live.

PFA cubicleThe PFA cubicle with HV fuse protection combined with a switch-disconnector opens the switch disconnector if a fuse blows.Thus all phases are off-load.The fuse is dedicated to this purpose only and is fi tted with a striker, which, via rods, triggers the operating mechanism opening.

Fuse accessTwo earthing switches are used to replace fuses without having to use auxiliary equipment:■ One with making capacity, upstream of the fuses, and■ One, without making capacity, downstream.The two earthing switches are operated simultaneously by a single spring-operated mechanism.

The interlocking guarantees maximum safety for the personnel during the replacement of fuses. The fuse compartment panel can only be opened if the cubicle has been earthed correctly. Inversely, the earthing can only be removed once the fuse compartment panel is closed and locked.

Replacement of fusesAccess to the fuses is via the front panel of the cubicle with the door to the cable compartment removed.When a fault causes the blowing of one or two fuses, the characteristics of the remaining fuses are decreased by the effects of the short circuit. It is thus recommended that you replace all three fuses in a cubicle (IEC 282-1).

Protecting capacity banksUse fuses of a rated current value just above 1.8 x the rated current value for the capacitor bank.

Equipment Low voltage equipment

Voltage detection systemsA VPIS (Voltage Presence Indicator System) indicates that the cubicle is energized. An auxiliary unit can be coupled up using contacts

Short circuit indicatorCubicles with outgoing feeders can be equipped, as an option, with DAX-I short circuit indicators (manufacturer: Schneider Electric). Other brands are available on request.The short circuit indicators are parameterized as follows depending on their type:■ Detection of earth and phase faults.■ Fault current measurement range: 100 to 1000 A.■ Earth fault current measurement range: 5 to 160 A.■ Reaction time: 40 to 999 ms.■ Manual or automatic reset.■ Autonomous power supply using a battery with a 10-year service life.■ Remote signalling contact,

CTOS toroidal type transformers acting as sensors for the short circuit indicators are installed on the cables.The DAX-I is integrated into the front panel in the low voltage part.The DAX is integrated into the substation.

Monitoring devicesThe DMX is used to monitor various pieces of digital data transmitted by the substation.This device can, notably, process status information from the MV/LV transformer, including temperatures, oil levels, etc. and transmit trip orders and/or alarms depending on its pre-defi ned confi guration.The RS485 connection and Modbus protocol means that the DMX can be fully controlled from a distance.

Directional short circuit indicator (D4X)The D4X detects and shows the direction of a fault along the MV network. This information is available internally (relays) and externally (green/red indicators) and is used to provide a rapid location of a faulty section. Its digital technology makes it very fl exible.The D4X is installed within the substation on compensated neutral networks.

Environment Sustainable development

Schneider has resolved to engage itself in a dynamic process of sustainable development through 6 commitments:■ To develop eco-design to reduce environmental impact of the products during their lifetime■ To reduce greenhouse effect gases related to SF6■ To develop environmental management and safety■ To participate in the local economy■ To develop a responsible purchasing policy■ To minimise impact on the environment by offering solutions allowing renewable energies to be connected to electrical networks.

Eco-design and impact on the environmentSchneider Electric contributes effi ciently to worldwide savings in terms of energy resources.

Fluokit replies to a high degree of ecological requirements related to environmental protection thanks to:■ The optimisation of consumption of materials and energy during manufacture■ The compliance with all ecological requirements during the service life of the product■ The use of materials that can be recycled for an effi cient valorisation.

A responsible designOur construction directives relating to an ecological design specify the use of materials that are easy to recycle and dismantle:■ The majority of the metals in a Fluokit switchboard can be recycled, as well as■ all thermosetting plastics and thermoplastics.

All the materials have been selected and developed in such a way that, for instance, a switchboard affected by a fi re in a building has a minimal impact on the load of the fi re (development of heat and toxic substances in the emissions).

Eco-declarations are available on request.

Environmental impactThe end-of-service life phase is considered a very important part of the life cycle of Schneider Electric products. The environmental impact inherent in the disposal of equipment is, sometimes, more polluting than that of the manufacturing, delivery or utilisation phases. European directives, such as WEEE, ELV and RoHS, have confi rmed this point and all insist upon the recovery of waste products and their valorisation at the end of the equipment’s service life.Even though our switchgear is not covered by this legislation, Schneider Electric is willingly attempting to optimise recycling, the processing of waste and, as a consequence, the end of service life phase of our products, which is an integral part of the operating costs.


At the end of the Fluokit’s service lifeThe destruction of the Fluokit at the end of service life is possible. The separation of the elements making up the switchgear will be made:■ Either by disconnecting the mechanical linkages,■ Or, by dismantling, that is to say, by breaking or shearing the connections.

To guarantee effi cient and ecological sorting and elimination of the materials, all plastic components have been identifi ed:■ A description of the materials is supplied to the customer with■ Information on the valorisation process, supplied to the companies in charge of the recycling.

End of service life processingSchneider Electric can help you in your Fluokit end-of-service-life processing approach.

SF6 gas recoveryThe volume of the insulating gas used in the Fluokit PGB corresponds to about 0.13 % of the total weight of the switchboard. At the end of the switchboard’s service life, in order to recycle the gas, it can be completely evacuated using a suitable recovery unit. And for this, the suppliers of the gas have developed an effi cient recycling method.

Composition of the materials and valorisation at end of service lifeAfter disassembly (or dismantling), the recovered elements must be forwarded for treatment in the following manner:
