General Information

GDF-5000/OL Online Insulation Monitoring Device for DC System is used for real-time online monitoring of insulation status of DC bus and branch. This device adopts the detection method of DC balanced resistance. It does not produce any AC or DC interference signal to busbar, and will not cause the artificial insulation resistance drop. It is suitable for power plants and substations of any voltage level.

GDF-5000/OL’s unique stability and anti-distributed capacitance make it more suitable for bus system under complex working conditions, standard instrument structure, compact size, convenient installation and better applicability.

GDF-5000/OL has LCD display, full software function control, perfect man-machine interface, easy operation and use.

Features

● Modular international standard industrial controller structure, standard shell, small size and light weight, easy installation and maintenance;
● Single/double bus up to 64 loop monitoring, DC balanced resistance detection method, no bus interference;
● Branch fast detection, inspection time is less than 20 seconds;
● The measured results are not related to bus distributed capacitance;
● Automatic/manual inspection of branches;
● The configuration of DC leakage current sensor is flexible and convenient.
● Isolated RS-485 communication interface, MODBUS/Emerson communication protocol is fully compatible;
● Industrial operating temperature range;
