Megger 220015V2 – 15 kV DC Dielectric Test Set

• Test Voltage Range: 0 to 7.5 kVdc and 0 to 15 kVdc; negative with respect to ground
• Current: 2 mA continuous; 5 mA for 12min
• Short Circuit: 12 mA max, limited by circuit breaker
• Accuracy: +/-2% of full scale

The Megger 220015V2 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 overvoltages such as lightning strikes and switching surges. Designed for field or shop use, the complete Test Set (including all leads) is housed in a durable, impact-resistant plastic case, with a removable lid and carrying strap. For safety in operation, the control panel of the test set is of grounded metal.

Megger 220015V2 Dielectric Test Set Applications

The Megger 220015V2 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 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 Megger 220015V2 is suitable for testing power cable, switchgear, and rotating machinery in accordance with IEEE, ICEA, NEMA, and ANSI guidelines. Because the Megger DC dielectric test set acts like full-wave rectified units, it is also suitable for applications involving vacuum bottles.
