Kyoritsu 3128 High Voltage Insulation Tester
The Kyoritsu 3128 is a digital CAT IV High Voltage Insulation Tester subsequent to the capabilities of psychiatry insulation resistance taking place to 35T, once test voltages going on to 12kV. The 3128 model is meant for arena use when an IP64 rating and features a large LCD display taking into consideration backlight.
The Kyoritsu 3128 is a microprocessor-controlled high voltage insulation resistance tester, following various logical functions. Such functions meet the expense of the take absorb to test the polarization index (PI), the dielectric absorption ratio (DAR) and the dielectric discharge (DD). Step voltage (SV) measurements can be applied, where successive voltage increments are implemented, to test the degradation of insulation. Insulation resistance can be measured occurring to 35T when test voltages going on to 12kV using this instrument.
