5 & 10 kV DC Insulation Resistance Testers
APPLICATION
The Insulation Resistance (IR) test is a quantitative test which
indicates the effectiveness of a product’s electrical insulation.
Applications include cables, transformers, motors/generators,
circuit breakers and bushings. Common insulation tests are the
“spot test”, a 1 minute IR test and a 10 minute Polarisation
Index (PI) test, where PI is the ratio R
10min
/R
1min
and temperature
independent.
