Product Desciption

Product Description

1.Description
WXH-822C Digital line protection and monitoring device realizes protection and monitoring functions of the circuit in the indirect earthing system (neutral non-grounding or through arc suppression coil earthing system) or the low resistance earthing system. This device is mainly applicable to protection and monitoring of circuit gap of 35kV and lower voltage classes. Flexible configuration of the operating circuit can adapt various operating mechanisms.

2.Features

Adopt "VLD" visual logic development tool with independent property right by XJ, featuring high software reliability.

2 Ethernet ports are configured to support IEC 60870-5-103 and IEC 61850 communication protocols.

Possess offline logic simulation function, to realize "transparency" of accident analysis.

Time hack: support SNTP time hack, GPS pulse time hack, B code time hack and 1588 time hack.

Thorough incident protection processing, storage of records of the top 80 latest event reports, with action report records of no less than 100, report 10 cycles of current and voltage report.
