High Voltage DC Insulation Testers measure leakage current by applying a DC voltage at or above the insulation system's operating level. This measurement determines the insulation system's ability to withstand overvoltages such as switching surges.

Megger portable HV DC Insulation Testers check the electrical insulation quality of many types of insulation sytems including, motors, power cables, switchgear, insulators, transformers, capacitors, etc. Typical applications include acceptance and maintenance testing of critical equipment used in electircal utility substations, industrial plant distribution systems, and demanding miitary environments. Power apparatus manufacturers may also use the equipment to perform QA/QC production tests.

The MIT30 can be used to perform step-voltage and proof tests, which when incorporated into a routine maintenance program, can aid in predicting potential failure before breakdown occurs.

Direct current high-potential teting provides several advantages over alternating current. Direct current test equipment uses far less power, provides fast charging of highly capacitive test samples, and can be easily transported to the test site and costs less.
