System Protection Protection and Supervision Functions 14 Locked Rotor Protection Each element has a single definite time overcurrent characteristic with settings for pickup level and definite time lag (DTL) delays. Operation can be controlled from motor stopped or running conditions. 27 Undervoltage Protection – Phase Each element has settings for pickup level, drop-off level and DTL delays. Operation occurs if voltage is below setting for duration of delay. ances on the system or remote earth faults when a delta-star transformer is in circuit. 47NPS Negative Sequence Overvoltage...

System Protection to bypass the time delays when the circuit-breaker is known to be faulty. 50G Instantaneous Earth Fault – Measured This function directly measures the earth current from an independent CT, or the residual connection of the 3 line CTs. 50G INST/DTL elements provide earth fault protection, each with independent settings for pickup current. 50GLC Line Check Earth Fault – Measured This function prevents a CB being repeatedly manually closed onto a faulted line. It is enabled upon the Manual CB Close output being issued. 3.1 50LC Line Check This function prevents a CB being...

System Protection method that considers the presence of negative phase sequence current, without an equivalent level of negative phase sequence voltage, for a user set time as a CT failure. Both element types have user operate and delay settings. 60VTS VT Supervision The VT supervision uses a combination of negative phase sequence voltage and negative phase sequence current to detect a VT fuse failure. This condition may be alarmed or used to inhibit voltage dependent functions. Element has user operate and delay settings. 64H Restricted Earth Fault Protection – High-Impedance The measured...

System Protection Virtual Inputs/Outputs There are 8 virtual inputs/outputs to provide internal logical states to assist in the application of the functions. Each virtual I/O can be assigned in the same way as a physical I/O. Circuit-Breaker Maintenance 2 circuit breaker operations counters are provided to assist with maintenance scheduling. The maintenance counter records the overall number of operations and the delta counter records the number of operations since the last reset. An I2t summation counter provides a measure of the contact wear indicating the total energy interrupted by the...
