Insulation resistance

Insulation resistance measurement on insulating materials, electrical devices and equipment

Insulation resistance testing of insulation materials and electrical appliances or equipment measures the simple effective resistance portion of an insulation. 

Insulation defects can generate leakage currents that could endanger the operator. The test makes sure that the measurement results are within the permissible range. The measurement also plays an important role when performing cyclic inspections. For the material testing of insulation materials, the test can also provide useful information about the quality of the manufacturing process.

ELABO test units enable versatile deployment options in manual or automated systems for the insulation resistance testing of electrical appliances and insulation materials. The switchable measurement range also enables flexible adjustment to a wide range of test specifications.
