Why we need to perform insulation resistance tester?This test is strongly recommended to prevent electrical shock for equipment,electric motor or electric cable.We also can determine any abnormal condition or leakage before installation and can rectify the problem.

Insulation resistance tester is the one of  important equipment/meter for determining the resistance of the insulation in motor winding, transformers winding or electrical cable in good condition or not.

This tool facilitates off to make an informed decision about the condition of equipments can be used again, whether or not based on the value of reading difficulties.According to standard IEEE 43: IR test minimum value of the electric motor is a 1 Mega Ohm ( 1 MΩ ) read more
