Non‑directional and directional phase overcurrent protection, earth‑fault protection, sensitive earth‑fault protection, thermal overload protection, phase unbalance protection, over‑voltage and under‑voltage protection. Optional multi‑shot auto‑reclosing, feeder fault‑location calculation and 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. Support sequential‑of‑event logging, COMTRADE disturbance recording and multiple setting‑group management. Built‑in comprehensive hardware self‑diagnosis, detect internal hardware faults and upload alarm information to local HMI and station control system. Configuration and parameter commissioning are completed via PCM600 engineering tool.
Installed in 19‑inch standard rack inside substation protection cabinet. Strictly follow CT polarity for secondary wiring, strictly prohibit CT secondary open‑circuit risk. Auxiliary power supply shall be kept within rated voltage range. After unit replacement, download complete project configuration file. Perform protection function verification test, breaker trip‑close loop test, binary input/output point‑to‑point signal test and station‑control communication validation. 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 feeders within radial, ring and meshed distribution networks. Can also serve as backup protection for transformer and motor bays.
