HZJY-25K 25kV Insulation Resistance Measuring Equipment

Intelligent high-voltage insulation resistance tester, with 8 ranges: 500V, 1000V, 2500V, 5000V, 10000V, 15000V, 20000V, 25000V, the maximum test can reach 25TΩ, and the manual voltage function.

Instrument use

1. Measure the absorption ratio DAR:

(1) Choose a measurement time longer than 1 minute

(2) Select the appropriate voltage and start.

(3) The instrument automatically records the resistance values of 15S and 60S, and calculates the absorption ratio after 60 seconds.

Absorption ratio calculation method: DAR= R60/R15;

2. Measure polarization index PI:

(1) Choose a measurement time longer than 10 minutes

(2) Select the appropriate voltage and start.

(3) The instrument automatically records the resistance values of 15S, 60S, and 600S, and calculates the polarization index after 600 seconds. Polarization index calculation method: PI= R600/R60;
