Traditionally, overcurrent protection of the transformer has been arranged as shown Figure 115 . The low-set stage (F)PHLPTOC operates time-selectively both in transformer and LV-side busbar faults.
Page 223 1MRS758755 C Protection functions on the transformer HV and LV-sides provide increased security degree of backup protection for the transformer, busbar and also for the outgoing feeders. Depending on the overcurrent stage in question, the selectivity of the scheme in Figure 116 is based on the operating current, operating time or blockings between successive overcurrent stages.

Blocking output = digital output signal from the start of a protection stage, Blocking in = digital input signal to block the operation of a protection stage The operating times of the time selective stages are very short, because the grading margins between successive protection stages can be kept short.

A brief coordination study has been carried out between the incoming and outgoing feeders. The protection scheme is implemented with three-stage numerical overcurrent protection, where the low-set stage (F)PHLPTOC operates in IDMT-mode and the two higher stages PHHPTOC and PHIPTOC in DT-mode.

Page 347 1MRS758755 C Protection functions In this case, the resistive part of the measured admittance is due to leakage losses of the protected feeder. As they are typically very small, the resistive part is close to zero. Due to inaccuracies in the voltage and current measurement, the small real part of the apparent neutral admittance may appear positive.
Page 348 Protection functions 1MRS758755 C Equation 16 shows that in case of a fault inside the protected feeder in unearthed networks, the measured admittance equals the admittance of the background network. The admittance is dominantly reactive; the small resistive part of the measured admittance is due to the leakage losses of the background network.

Page 526 Supervision functions 1MRS758755 C Figure 263: Operating principle of the trip-circuit supervision with an external resistor. The TCSSCBR blocking switch is not required since the external resistor is used. If TCS is required only in a closed position, the external shunt resistance can be omitted.

The circuit breaker open indication is set to block TCSSCBR when the circuit breaker is open. Trip circuit supervision and other trip contacts It is typical that the trip circuit contains more than one trip contact in parallel, for example in transformer feeders where the trip of a Buchholz relay is connected in parallel with the feeder terminal and other relays involved.

Page 530 Supervision functions 1MRS758755 C An auxiliary relay can be used between the protection relay trip contact and the circuit breaker coil. This way the breaking capacity question is solved, but the TCS circuit in the protection relay monitors the healthy auxiliary relay coil, not the circuit breaker coil.
Page 531 1MRS758755 C Supervision functions Using power output contacts without trip circuit supervision If TCS is not used but the contact information of corresponding power outputs are required, the internal resistor can be by-passed. The output can then be utilized as a normal power output.

Only the protection relay R3 has an internal TCS circuit. In order to test the operation of the protection relay R2, but not to trip the circuit breaker, the upper trip contact of the protection relay R2 is disconnected, as shown in the figure, while the lower contact is still connected.

1MRS758755 C Requirements for measurement transformers Requirements for measurement transformers 12.1 Current transformers 12.1.1 Current transformer requirements for overcurrent protection For reliable and correct operation of the overcurrent protection, the CT has to be chosen carefully. The distortion of the secondary current of a saturated CT may endanger the operation, selectivity, and co-ordination of protection.
Page 832 Requirements for measurement 1MRS758755 C transformers The CT accuracy primary limit current describes the highest fault current magnitude at which the CT fulfils the specified accuracy. Beyond this level, the secondary current of the CT is distorted and it might have severe effects on the performance of the protection relay.
Page 833 1MRS758755 C Requirements for measurement transformers Delay in operation caused by saturation of current transformers The saturation of CT may cause a delayed protection relay operation. To ensure the time selectivity, the delay must be taken into account when setting the operate times of successive protection relays.

The type is selected by setting jumpers X19, X20, X21 and X26. The jumpers are set to EIA-232 by default. Table 740: EIA-232 and EIA-485 jumper connectors for COM1 Group Jumper connection...
Page 846 Protection relay's physical connections 1MRS758755 C Group Jumper connection Description EIA-232 To ensure fail-safe operation, the bus is to be biased at one end using the pull-up and pull-down resistors on the communication module. In the 4-wire connection, the pull-up and pull-down resistors are selected by setting jumpers X5, X6, X8, X9 to enabled position.
