Non‑directional / directional phase overcurrent protection, earth‑fault protection, sensitive earth‑fault protection, thermal overload protection, phase unbalance protection, over‑voltage / under‑voltage protection. Optional auto‑reclosing, fault‑location calculation, arc‑flash detection function. Realize local & remote circuit‑breaker control, bay‑level interlock logic and trip‑circuit supervision. Perform high‑accuracy measurement for current, voltage, active/reactive power, energy and frequency. Sequence‑of‑event logging, disturbance waveform recording and multi‑setting‑group management. Comprehensive hardware self‑diagnosis, detect internal hardware fault and upload alarm status to local HMI and station control system. Configuration and maintenance are completed via PCM600 engineering tool.
Installed in 19‑inch standard rack of substation protection cabinet. Strictly comply with CT polarity for secondary wiring, avoid CT secondary open‑circuit hazard. Auxiliary power supply shall be kept within rated voltage range. After unit replacement, download complete project configuration file, execute protection function test, breaker trip‑close loop test, binary input/output point‑to‑point signal test and station‑control communication verification. Confirm no hardware self‑diagnosis fault alarms.
Medium‑voltage feeder protection for power plants, urban substations and industrial power distribution systems. Applicable for overhead‑line and cable feeder in radial, ring and meshed distribution networks, also can be used as backup protection for transformer and motor bay.
