During the operating process of Neutral grounding resistor, intelligent monitor and protection device is required because the huge changes of fault current and temperature. MRD-ZRK Intelligent Monitoring Device for Neutral Grounding Resistor is designed to monitor the cabinet temperature, resistor temperature, grounding fault current and time, and also numbers of grounding fault, enable to monitor the real-time conditions in the cabinet.
Apply high speed and reliable CPU to make sure the long term and stable system operation
According to the acquired signal and processing result to send relative signal. E.g. monitor the real-time temperature in the cabinet to adjust ambient temperature and humidity automatically as per the presetting operation parameter.
When the detected earth current is higher than the set alarming current value, the device sends out alarm signal
The device can record and display ground times, the recent 20 times ground fault information can be inquired
Equipped with auto-heating and auto-starting fan function, the device can start heating automatically according to the cabinet inside temperature and start the air cooling function automatically as per the resistor temperature
The principal computer can visit the monitor and get its response signal through 485 communication interface to acquire the real-time operation parameters of resistor
Altitude: lower than 4000m
Temperature: -10~60 c
Relative Hudity: less than 90%(no condensstion) at 25c
There is no corrosive air, steam, conductive dust, explosive air and insulation-damaging air around the site.
There are windproof, rainproof and dustproof facilities at the location site.
