Product Description
GDDW Insulation Resistance/Earth Resistance Test Set



I. Application

1) GDDW Insulation Resistance/Earth Resistance Test Set adopts new type variable frequency AC power supply and microcomputer processing control, signal processing and other measures, which can properly solve the interference problem during test, simplify test operating process, improve precision and accuracy of test results as well as greatly reduce labor intensity of testers and test cost.

2) GDDW Insulation Resistance/Earth Resistance Test Set is applicable to the power frequency earth impedance, contact voltage, step voltage, equal power frequency characteristics and soil resistivity of various grounding devices, which can test earth network of substation (4Ω ), hydraulic and thermal power plants, microwave station (10Ω ), arrester (10Ω ) multipurpose machine types.
