The Doble M4100 High Voltage Apparatus Tester is a peak Power Factor/Tan-Delta tool to conduct reliable insulation testing. The M4100 Tan-Delta instrument collects comprehensive analysis on the insulation of a device, finding any leaks in electric current or damage to the windings or turns that may affect performance. Dissipation factor testing is easier with artificial intelligence analysis software and features like self-calibration or capacitor bank testing to find any signs of deterioration.

The Doble M4100 Power Factor/Tan-Delta instrument is trusted worldwide for insulation testing with dual safety switches and ground earth relay interlocks to ensure safer tests. The M4100 High Voltage Apparatus Tester also creates a specific sine wave test signal for results that can be trusted.
