Answer Posted / t k shaw
Polarization Index Test ( PI ) – The PI test measures the
ability of the insulation to absorb voltage over a period
of time. This gives and indication of the overall
insulation quality of the individual pieces of insulation
in the transformer. This test is usually performed in
conjunction with the Megger Test.It is measured as ratio of
insulation resistance (IR)for 10 minutes to insulation
resistance for 1 minute.
