DC Hi-Pot Tester | Models: 3010HP, 3025HP, 3050HP

The DC Hi-Pot Test is a critical electrical safety test mandated worldwide, identifying insulation weaknesses caused by dirt, grease, humidity, and temperature stress. Over 80% of electrical and electronic system failures stem from poor insulation, making Hi-Pot testing essential for ensuring system reliability and operator safety.

These testers provide a cost-effective and precise solution for performing Hi-Pot tests across a range of electrical equipment.

Rotor Fault Detection Feature

In addition to Hi-Pot testing, the integrated Rotor Tester identifies faults in aluminium and copper die-cast rotors by detecting induced magnetic field irregularities via sinusoidal waveform analysis.

faults detected

  • Broken or interrupted rotor bars

  • Poor or missing connections to end rings

  • High bar resistance

  • Short circuits between two or more bars

  • Misalignment of commutator and slots

  • Non-uniform lamination of commutator

  • Deviation in skew angle

This feature provides a clear, real-time waveform display to correlate rotor bar conditions with motor torque performance.
