ShZZP is designed to protect connections from ground faults in isolated and resonant neutral systems. Security features are performed by MKZZP-6-35-I (K) microcontroller ground fault protection device for 6-35 kV bus sections, which selectively disables connections in case of ground fault or shows a number of a damaged connection without disabling.
Protocols record all controlled parameters, date and time of operation.
Protection makes oscillography records of all channels and transmits the monitored parameters and logic signals via serial comm link (RS-485) to the control computer.
