Eaton's CYME Distance Protection Analysis module verifies the operation of all types of distance relays modeled, under normal conditions and under all fault types (LLL, LLLG, LL, LG and LLG).
Relays settings can be done automatically or manually in both primary and secondary sides. The user can select the right distance protection device and the software will help calculate its appropriate settings. Voltage and current are used for computing impedance.
Distance relay types that can be modeled with Eaton's CYME software are:
The fault and the relay impedance can be displayed in an R-X plane from the report. The user can examine the relay operation every time the system conditions are changed.
