The Megger 220015 15 kV DC Dielectric Test Set measures leakage current while applying a DC voltage at or above the insulation system’s operating level. This measurement aids in determining the insulation system’s ability to withstand over-voltages such as lightning strikes and switching surges. The Megger 220015 15 kV DC Dielectric Test Set checks the electrical insulation quality of motors, power cables, switchgear, insulators, transformers and capacitors. Typical applications include acceptance and maintenance testing of critical equipment used by electrical utility substations and industrial plant distribution systems. Power apparatus manufacturers may also use the equipment to perform QA/QC production tests.

The 220015 Test Set 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.

The 220015 Test Set is suitable for use on equipment rated 7.5 kV and below. It is also suitable for testing power cable, switchgear and rotating machinery in accordance with IEEE, ICEA, NEMA and ANSI guidelines.

Because the Megger 220015 15 kV DC Dielectric Test Set acts like a full-wave rectified unit, it is also suitable for applications involving vacuum bottles.
