Overview
Information is exchanged with the remote station so that the ground-fault protection switches off immediately and selectively on the entire line for all errors. The “Teleprotection with ground fault protection” methods are used in protection function groups with a voltage-measuring point in combination with the Ground-fault protection function.
For more detailed information on “Teleprotection with ground fault protection” methods, refer to SIPROTEC 5 devices, V8.30 & higher manuals.
