The ground distance protection can suppress over-reaching or under-reaching trip during a protection operation.
The CYME Distance Protection Analysis module is designed to help electrical engineers design and validate protection schemes that involve distance protection relays.
The new standard for distance protection: IEC 60255-121
A method of phase-to-phase distance protection for preventing mal-operation during overload is provided.
The present invention is concerned with a method of distance protection of parallel transmission lines applicable both to series compensated and uncompensated electric power lines, using a distance relay.
For protection of current conducting parts and metallised intermediate layers on the roof with protection by distance, no protection degree is required.
