What is a high-voltage insulation tester?

Quality electrical insulation is of paramount importance in virtually any electrical system, not only ensuring reliable operation but also reducing the risk of electrical surges to electrical equipment and personnel. External physical and chemical factors slowly degrade the insulating material, which can fail at the most inopportune moment.

Changes in the dielectric properties of insulation materials that can lead to failure are best detected by high-voltage testing using high-voltage insulation testers, megohmmeters, or megohmmeters as they are commonly known.

High Voltage Insulation Tester Ir3455


In the high-voltage system, the insulation resistance is measured with a 5000-volt DC megger for voltages up to 6.6 kV. In addition, the insulation resistance is measured under the following conditions. Routine inspection according to the planned maintenance system (PMS).
