As part of a planned maintenance program, the LIFEVIEW® QTD enables you to monitor both the PD and Tan Delta (Loss Factor) of your winding insulation. With a built in PD coupler, designed to take partial discharge measurements; rated up to 20kV phase to ground and with three switchable measuring ranges, the LIFEVIEW QTD is an essential tool to monitor the ageing of your rotating electrical asset.


Monitoring PD and Tan Delta

The LIFEVIEW QTD can be either fully supplied to you with the benefit of detailed training, or available to you as a service with our experienced engineers providing the analysis you need.

  • Integrated approach to PD and Tan Delta measurements
  • Rated up to 34kV or 50kV
  • Measures Tan Delta in both grounded and ungrounded modes (ungrounded for process coil testing)
  • Suitable for operation with all LIFEVIEW Partial Discharge sensors
  • A high voltage power source is required
