Megger HV Tester 25 kV and 25 kV Digital

The Megger HV Tester 25 kV and HV Tester 25 kV Digital are portable high-voltage generators designed for DC and insulation testing of cables, joints, electrical fixtures, and similar equipment. With a variable negative DC output voltage ranging from 0 to 25 kV, these compact, lightweight, and robust instruments offer exceptional flexibility thanks to their built-in rechargeable battery, making them ideal for field testing where no external power supply is available.

Both models feature an internal discharge facility that safely and automatically discharges capacitive loads, such as shielded cables, during breakdowns or after testing. The standard model includes analogue meters, while the digital version provides precise voltage and current reading through clear digital metering. A built-in timer (1 to 30 minutes) adds further convenience and control during testing.

These instruments are suitable for testing paper-insulated and mass-impregnated cables in accordance with IEEE 400-2012 and IEC 60060-3, for electrical equipment testing as per IEEE 62.1 and IEEE 95, and for cable sheath or outer jacket testing in compliance with IEC 60502 and IEC 60229.
