Product Description
Features
FM160 intelligent resistor monitoring device during normal system operation can be monitored when the neutral unbalance current, resistor temperature (the highest temperature up to 1000 ºC); single-phase ground fault, can record instant resistance, grounding time, sheet resistance temperature changes and ground operation frequency and RS485 communication interface, MODBUS protocol to be seized. Measured, recorded information is transmitted to the control room or computer unit, remote control. Intelligent control section in strict accordance with the implementation of the relevant national standards for manufacturing.
Pac
eutral grounding resistors are made of special stainless steel electric-heat metal imported from US.They are with outstanding characters such as high temperature-resistant capability,excellent anti-oxidation performance,strong tensile characteristics,high resistivety and stable resistance value,what's more,it can sustain elec-tric and thermodynamic performance even under 1000°C,which enables safe and reliable operation.
According to different connection mode or various customer requests,we can provide epoxy resin to cast dry type transformers,zero sequence current transformers,single-phase discon-necting switches,heater and thermo/humidity controllers etc.
