Practical emv relay protection
WebProtective relay continuously monitors power system condition. Improves system performance, system stability, system reliability. Disconnects the faulty parts as quickly as possible, so as to minimize the damage to the fault parts themselves. Detect system failures when they occur and isolate fault areas from the rest of the system.
