HIGH VOLTAGE INSULATION TESTER HIGH VOLTAGE INSULATION HiTESTER 3455 Maximum 5kV Test Voltage - Up to 5TΩ of Insulated Resistance Testing Safely evaluate the insulation characteristics of high voltage transformers, motors and cables Wide voltage range (250V to 5kV) for maximum 5TΩ of insulation resistance measurements Automatically calculate and display the PI (Polarization Index) and DAR (Dielectric Absorption Ratio) for all types of insulation evaluations Temperature compensation to accurately
HIGH VOLTAGE INSULATION TESTER n Primary Measurement Functions z Leakage current display z Insulation resistance measurement When measuring insulation resistance, the instrument can be switched to display leakage current. This is possible before, during, and after measurement. Measurement voltage is selectable from 250 V, 500 V, 1.00 kV, 2.50 kV, and 5.00 kV. More finely graded settings are also possible.
