General DescriptionThe 0.2 kW Protective Relaying Training System is a complete program that extends training in protective relaying beyond the operation and calibrations of individual relays into broader circuit applications. The program provides hands-on training at the system level in Generator Protection, Transformer Protection, and Induction Motor Protection.

The 0.2 kW Protective Relaying Training System consists of several modules, which can be divided into five groups: Common Electrical Modules, Power System Modules (Series 3700), Protective Relaying Control Station, Protective Relays (Series 3800), and Additional and Optional Equipment. These modules are described in detail below:

Common Electrical Modules – Power supply, synchronous generator, induction motor, prime mover / dynamometer, resistive loads, voltmeters, ammeters, and others. Most of these modules are part of the 0.2 kW ElectroMechanical System (EMS), Model 8001 or 8006.

Power System Modules, Series 3700 – Modules specially designed for training in the protective relaying area, including current transformers, voltage transformers, power transformers, source impedances, a transmission grid, and others. These modules are designed to be installed in an EMS workstation.

Protective Relaying Control Station – A mobile rack for protective relay operation, including a dc power supply, dc control relays for system studies, and an interconnection panel to facilitate connection of the protective relays to the system to be protected.

Protective Relays, Series 3800 – Selection of protective relays. Each relay is mounted on a metal panel which facilitates relay installation in the Protective Relaying Control Station. Each relay panel is equipped with fault switches that allow fault insertion for troubleshooting at the system level. The following types of protective relays are available: undercurrent/overcurrent, undervoltage/overvoltage, synchronism check, underfrequency/over-frequency, phase balance, phase sequence, reverse power, and power factor.

Additional and Optional Equipment – Various modules, such as distribution busses, a ring bus, transmission lines, distribution transformers, protective relays, and reactive loads are available. These modules can be added to the basic 0.2 kW Protective Relaying Training System to allow the instructor to create more elaborate hands-on exercises.

The 0.2 kW Protective Relaying Training System courseware consists of a student manual and an instructor guide. The student manual is divided into several units, each consisting of a series of hands-on exercises dealing with one of the fields of protective relaying mentioned above. Each exercise provides a clearly stated objective, a discussion, textbook references, a summary of the exercise procedure, a detailed exercise procedure, a conclusion, and a set of review questions. A ten-question test at the end of each unit allows the student to verify what was learned in the unit. Completion of some exercises in the student manual requires a digital storage oscilloscope and a digital multimeter, which must be purchased separately.

The instructor guide contains the practical results as well as the answers for each hands-on exercise in the student manual. It also contains the answers to the unit test questions in the student manual. The reference textbook provides more elaborate discussions of the theory presented in the student manual.

The prerequisites for the 0.2 kW Protective Relaying Training System include: completion of a course in relay operation and calibration, and completion of a course in electric power technology that covers electric power generation, power transformers, and induction motors.

The modular structure of the 0.2 kW Protective Relaying Training System, together with the subdivision of student manuals into topical units, enables instructors to choose equipment that matches their budgets while progressively enhancing their systems over time.

For power utility users, it is possible to combine their own protective relays with a selection of modules from the 0.2 kW Protective Relaying Training System to obtain equipment setups that correspond to existing one-line and three-line diagrams.

Phase Balance/Sequence Relay 3822-15

The Phase Balance/Sequence Relay is sensitive to phase unbalance, phase reversal, and phase loss in three-phase power systems. It can be used to initiate an action should any one of the hazards mentioned above occur. For instance, the sensitivity to phase unbalance allows protection of a three-phase induction motor against excessive temperature rise due to unbalanced supply voltages. Unbalance setpoint and time delay adjustments as well as two sets of

contacts are provided. The adjustable time delay is a useful feature which can prevent premature relay operation on short duration supply fluctuations.

Reverse Power Relay 3824-25

The Reverse Power Relay is sensitive to the reversal of active power in single-phase and three-phase four-wire power systems. In systems where a generator is connected in parallel to other generators or to a power system bus, this relay can be used to prevent the generator from motoring in the event the driving force applied to that generator fails. Reverse power setpoint and time delay adjustments are provided along with two sets of

contacts.

Motor Power-Factor Relay 3825-15

The Motor Power-Factor Relay is a protective relay that is sensitive to power factor. Because the phase angle between the motor current and voltage, and thus, the power factor, is dependent on the mechanical load applied to the motor, this relay can be used to detect either underload or overload conditions for a three-phase induction motor. Power factor setpoint and start delay adjustments, and an underload/overload selection switch are provided along with a single set of

contacts. The adjustable start delay is a useful feature which prevents the relay from tripping while the motor is starting.

*Note

The Power Supply cannot supply all the amounts of current indicated by the current ratings on its front panel at the same time. The current indicated for the fixed ac three-phase output section can only be obtained if no current is drawn from any other section, because this section is protected by the main circuit breaker common to every section. If currents flow in other sections, the available current for the fixed ac three-phase output section decreases. The variable ac output section and the variable dc output section are protected by a common set of circuit breakers placed after the fixed ac three-phase output section, which means that the current capacity has to be shared between the two sections. For instance, if current of the variable dc output section is at 70% of its nominal value, current drawn from the variable ac output section should not exceed 30% of its nominal value. The fixed dc output section is also protected by circuit breakers placed after the fixed ac three-phase output section.

Power Diodes 8842-15

The Power Diodes consists of six power diodes mounted in a half-size EMS enclosure. Each individual diode is protected against overcurrent and short-circuits by a thermal-magnetic circuit breaker. All the anodes and cathodes of the diode are terminated on the front panel by color-coded, 4 mm safety banana jacks. The diodes are interconnected in three groups of two, i.e., one group for each phase of

the power supply. To reduce the number of external connections on the front panel, the upper cathodes can be connected together as well as the lower anodes, through the use of a toggle switch.

Four-Quadrant Dynamometer/Power Supply 8960-B5

The Four-Quadrant Dynamometer/Power Supply is a highly versatile USB peripheral designed to be used in the Electric Power Technology Training Systems. Two operating modes are available: Dynamometer and Power Supply. A wide variety of user-selectable functions is available in each operating mode.

In the Dynamometer mode, the unit becomes a four-quadrant dynamometer that can act as either a

fully configurable brake (i.e., a mechanical load) or a fully configurable prime mover (i.e., a motor drive). In the Power Supply mode, the unit becomes a four-quadrant power supply that can act as a dc voltage source, dc current source, ac power source, etc.

In each operating mode, key parameters related to the selected function are displayed. Speed, torque, mechanical power, and energy are displayed in the Dynamometer mode while voltage, current, electrical power, and energy are displayed in the Power Supply mode. Optional functions, such as a small wind-turbine emulator, a hydraulic turbine emulator, a solar panel emulator, battery chargers, an SDK (Software Development Kit) etc., can be added to the standard functions to further enhance the training possibilities of the Four-Quadrant Dynamometer/Power Supply.

Two modes are available to control the function which the Four-Quadrant Dynamometer/Power Supply performs: Manual and Computer-Based.

In the Manual control mode, the module operates as a stand-alone unit, and the function performed is selected, set, and monitored using front-panel mounted controls and display. This mode provides access to all basic functions. In the Computer-Based control mode, the function performed by the module is selected, set, and monitored using the LVDAC-EMS software. In this mode, communication between the Four-Quadrant Dynamometer/Power Supply and the host computer running the LVDAC-EMS software is achieved through a USB connection. This mode provides access to all basic functions, as well as to additional advanced functions.

Workstation (Optional) 8134-20

The Workstation is a fully assembled workstation that serves the same purpose as the Mobile Workstation, Model 8110-2, but has no storage cabinet or pull-out work surface. This workstation is intended for use on a bench (not supplied) and is fitted with rubber feet to protect the bench top. Alternatively, this workstation can be mounted on either a Mobile Storage Cabinet, Model 89117-1, to make a Mobile Workstation, Model 8110-2, or on a Mobile Base, Model 88863, to make a mobile workstation without storage cabinet. In that case, it is possible to mount and lock a second

Workstation, Model 8134-2, on top of the first Workstation to double the space available for EMS modules.

The Workstation consists of three rows of compartments designed to house EMS modules. Two of these rows have full-height compartments while the other row has half-height compartments. Each row of full-height compartments can accommodate up to three full-size EMS modules or six half-size EMS modules whereas the row of half-height compartments can accommodate up to three half-size EMS modules.



Module Installation

The EMS modules are guided into position along stainless steel guide rails. Separators between each bay of the workstation ensure perfect alignment of the EMS modules and allow their easy insertion in the workstation. A holding mechanism ensures that each EMS module stays in place once it is installed in a compartment of the workstation. Front-mounted push levers allow all EMS modules on a single row to be released for easy removal.

Safety Padlock Bars



Six holes in the rear panel of the workstation allow connection to a power supply, as well as the connection of 2 kW machines to their interconnection modules. Assembly of the workstation before painting ensures that each EMS module in the workstation is correctly grounded.

Inductive Load (Optional) 8321-05

The Inductive Load consists of a module housing nine iron-core power inductors arranged in three identical banks. Each bank consists of three inductors connected in parallel that can be switched on or off with toggle switches to obtain various inductance values. This allows the equivalent inductance of each bank to be increased or decreased by steps. Six

safety banana jacks on the module front panel provide access to each inductor bank. The three inductor banks can be connected separately for operation in three-phase circuits. Also, the three inductor banks can be connected together for operation in single-phase circuits.

The Inductive Load is commonly used in conjunction with other basic load modules, like the Resistive Load and the Capacitive Load to experiment with the effects of different types of load on a circuit.

Capacitive Load (Optional) 8331-05

The Capacitive Load consists of a module housing nine capacitors arranged in three identical banks. Each bank consists of three capacitors connected in parallel that can be switched on or off with toggle switches to obtain various capacitance values. This allows the equivalent capacitance of each bank to be increased or decreased by steps. Six safety banana

jacks on the module front panel provide access to each capacitor bank. The three capacitor banks can be connected separately for operation in three-phase circuits. Also, the three capacitor banks can be connected together for operation in single-phase circuits.

A permanently connected discharge resistor reduces the voltage across the terminals of each bank of capacitors to 5% of the applied voltage within 25 seconds after the load is disconnected from the supply. The Capacitive Load may be used with both dc and ac power.

The Capacitive Load is commonly used in conjunction with the other basic load modules, the Resistive Load and the Inductive Load to experiment with the effects of different types of load on a circuit.
