Insulation protection relay DCG-UBCH2

2 NODCgrid and system

GYDCG-UBCH2 series products are used for on-line monitoring dc floating land system is thecathode of insulation resistance of thedevice, it is based on the principle of unbalanced bridge, toavoid the balance bridge across the electrodes in the problems of grounding fault cannot be detectedat the same time, at the same time, this series product can change greatly in the dc voltage, under thecondition of accurate measurement of electrical resistance, and short measurement period, adopt themethod of adaptive adjustment measure time, avoid is negative to the influence of the capacitance.This series product is 200-850-v dc system,measuring conditions 1 kΩ~ 10 mΩresistancerange, at the same time also can detect the dc voltage value, the user can through the RS485communication to realize the measured value.
