4 Protection functions
4.1 HS/LS OC protection (Both MODEL 1 and MODEL 2)
Both HS and LS OC protections can be selected as instantaneous or definite timedelayed protection according to the time delay setting. If the time setting is zero, it will beworked as instantaneous over current protection. Otherwise will be definite time delayover current protection.
These two protections can be configured as forward directional, reverse directional ornon-directional. And the non-directional element will block the forward and the reverseelements. Characteristic angle of directional element is selectable, 30° or 45°. These twoover current protections are all blocked by VT fail.
Direction element adopts 90o connection (shown as Tab.1), and it takes effect to A, B, C
phase respectively. The direction arrangement of U/I is shown as Fig.2. To avoid deadzone when voltage is too low to determine direction, direction element takes the voltagememory.

4.9 VT supervision
Voltage transformer supervision can supervise bus voltage and report single-phasebroken, two-phase broken and three-phase broken. Any of the following conditionssatisfy and last 9 seconds, CSC-211 will report the alarm of ‘TV broken or no-voltage’.
� Self-generated zero sequence voltage and three-phase voltage are all less than 8V,
CSC-211 Numerical Backup Protection equipment Manual
-17-
and any phase current is more than 0.125A (considered as no-voltage);
� Self-generated zero sequence voltage is more than 8V, and minimum phase-to-phase voltage is less than 16V (considered as two-phase broken);
� Self-generated zero sequence voltage is more than 8V, and the difference betweenmaximum phase-to-phase voltage and minimum phase-to-phase voltage is morethan 16V (considered as single-phase broken).
For the directional protection, the perfect bus-voltage is significant to their operation.Therefore, VT fail will block the protection with directional elements, under voltage, andunder frequency.

6 Measurement and Control
6.1 Measurement
The CSC-211 equipment monitors permanently all the current and voltage inputs,calculates the frequency, the phase to phase voltage, P, and Q, shows the values on theLCD display and stores the measurements in memory. The measured values aremeasured by the independent high precision module, which can ensure the true RMSwith 0.2% accuracy (nominal conditions).
Instantaneous measurements
Phase current: Ia, Ib, Ic;
Phase voltage: Ua, Ub, Uc;
Three phase active power P, reactive power Q, power factor;
Frequency;
Forward/reverse active power, forward/reverse reactive power;
Mean, maximum, minimum value of the current and voltage during some time;
Sequence currents and voltages;
Thermal status.
6.2 Operation method control
The settings are divided into two categories: protection settings, and control and supportsettings. 32 setting groups are provided for different operating conditions and adaptiverelaying. The soft function pressboards are provided for activation or inhibition of theprotection element. All settings and the states of the soft function pressboards are storedin E2PROM.
6.3 Programmable scheme logic
The programmable scheme logic feature of support software EPPC allows user tocustomize the protection and control functions. It is also used to program the functionalityof the optically isolated inputs, relay outputs and LED indications. The trigger conditionsand the record length could easy set by this function.

7 Fault Record and Analysis
The CSC-211 equipment can supervise the operation information of the devices andcorrelative circuit, which include fault records, events records, disturbance records andoperation records. The internal real-time clock provides the time time-tag for all typerecords, the time distinguish ability is 1ms. The networks synchronization and the GPSpulse (adaptive second or minute pulse) synchronization are supported by the real-timeclock system. A lithium battery provides a backup for the real time clock and all records inthe event of supply failure. This battery is supervised and easily replaced from the front ofthe relay.
7.1 Fault records
Records of the last 40 faults are stored in battery backed memory. Some important dataduring the fault or manual operation are record. The information provided in the faultrecord includes:
Fault time tag: date and time
Operation event table: operation protection, operation time
Operation data: current, voltage, frequency, phase angle
Active setting groups
States of the soft function pressboards
7.2 Disturbance records
Disturbance records are used to capture the analog and digital data of certain lengthbefore or after some event, it can reappearance the operation states of the devicesduring the fault period, any logic element and digital input could trigger the disturbancerecords. The internal disturbance recorder has 12 analogue channels, 32 digital channels(digital inputs, digital outputs, element states) and time tag. Data is sampled 20 times acycle and typically 10 disturbance records, each of up to 10 seconds duration are storedin battery backed memory. Disturbance records can be extracted from the relay via theremote communications and saved in the COMTRADE format. These records may beexamined using support software EPPC.
7.3 Events records
Up to 1000 time-tagged event records are stored in battery backed memory, and can beextracted using the communication ports or showed on the front panel display. The event
CSC-211 Numerical Backup Protection equipment Manual
-22-
records include: operation events, alarm events, changing of digital input state or digitaloutput state, time tag and the current status of the protection.
7.4 Operation records
The latest 40 time-tagged operation records are stored in the battery backed memory, itincludes: the modification or switch of the setting groups, close or open control of thecircuit breaker. These data could provide information for the detailed fault analysis.
8 Communications
All models of CSC-211 series equipments provide the following communications portsand protocols for the user:
� Double or single 10M Ethernet port of cable or fiber.
� One RS485 communication port
� One RS232 debug port
� IEC60870-5-103
CSC-211 equipment can transmit real-time data to the local monitoring system, orremotely to the SCADA, these data include settings, measurements and alarms, as wellas fault, event and disturbance records. The communication settings (relay address, datarate, parity, etc.) can be programmed using the relay front port. Software allows easysetting of any CSC-211 model, in addition to uploading of event, fault and disturbancerecords, settings and measurements.
The detailed protocols are provided in the products manual.
9 Diagnostics
Automatic tests including power-on diagnostics and continuous self-monitoring, ensure ahigh degree of reliability. When any abnormal status is detected, the alarm indicators andrelated relay are driven, and the dependent events could be record immediately. Forsome fatal faults, the relay could be blocked to avoid the unwanted operation. The resultsof the self-test functions are stored in non-volatile memory.
The virtual test function is provided for the automatic tests of the substation automationsystem. The function contains automatic counter point of digital input, automatictriggering of SOE.
Test features available on the user interface provide examination of input quantities,states of the digital inputs and relay outputs. A local monitor port provides digital outputs,selected from a prescribed list of signals, including the status of protection element, andmay be used in conjunction with test equipment. These test signals can also be viewedusing the communications ports, and the front panel user interface.
