Insulation tester is used for as the name says to determine the
level of insulation available. Insulation is measured in units of
ohms. and the higher the readings the better is the electrical
insulation.The test is done across the conductor and its insulation.

Answer / thowsif_csm_emerson

An insulation tester can be used to determine the integrity
of windings or cables in motors, transformers, switchgear,
and electrical installations. The test method is determined
by the type of equipment being tested and the reason for
testing.
