Diagnostics of medium and high voltage cables provides the opportunity for early detection of weaknesses and preventative maintenance work to be carried out before the cable fails in service. Partial Discharge diagnostics (PD) allows a precise analysis of cables and their joints and terminations. Tan Delta diagnostics (TD) provides a clear statement about the overall dielectric condition of aged polymeric cables.

The HV Diagnostics PDTD120 Partial Discharge System and Tan Delta Diagnostics provides a pure sinusoidal output voltage with stable frequencies. This is a pre-condition of direct comparison of PD and TD diagnostics results across cables of different lengths.

The HV Diagnostics PDTD120 Partial Discharge System and Tan Delta Diagnostics features:

• System rated to 120kV
