Measurements which are more and more in demand:
The polarization index (PI) is a long-term insulation measurement, during which measured values obtained after one minute and after ten
minutes are compared with each other.
Insulation resistance values acquired over a period of ten minutes may provide information regarding defects, as well as penetration by
contamination or moisture. If the insulation is intact, insulation resistance is initially low, and then increases. The curve usually flattens
out in the case of contamination or moisture. IEEE standard 43-2000 specifies reference values for measurements at motors and
generators.
These measurements can be performed with the METRISO XTRA and Metriso PRIME+ with any measurement voltage. Whereas the
polarization index (PI) is used with preference for large objects, the dielectric absorption ratio (DAR) serves as a subset of the polarization
index for smaller machines. In this case, insulation resistance measurements after 30 and 60 seconds are compared with each other.
