NEVA-OPF Fault Detection Device for Identifying Damaged Feeders in 6-35 kV Networks

The device "NEVA-OPF" is designed to detect a damaged feeder in 6-10-35 kV networks with insulated neutral, as well as in networks with resistively earthed or compensated neutral.

The application of the device "NEVA-OPF" allows to predict the condition of cable lines with the possibility of putting out of operation the cable with developing insulation defect before the occurrence of stable single-phase fault.
