GD3127 Series High Voltage Insulation Resistance Tester
GD3127 Series Insulation Resistance Tester is widely used in maintenance of electrical equipment in transformer substation, power plant, etc. It is suitable for carrying out measurement of insulation resistance(IR), polarization index(PI), absorption ratio (DAR), ramp(RAMP), filter(FR, 10s, 20s, 30s, 40s 4 choices), voltage(V), current(nA) of all kinds of high voltage equipment, including switchgear, transformers, reactors, capacitors, motors, generators and cables, etc.
GD3127 Series is the perfect test tool for early identification and discovery of preventive or predictive maintenance plans for potential equipment failures. It is of great significance to ensure product quality and the safety of people and equipment in operation. The insulation performance of electrical products is one of the important signs to evaluate the insulation quality, which is reflected by the insulation resistance test.
