Description
The HV Diagnostics HVA28TD provides very-low-frequency AC and DC high-voltage testing with integrated tan delta diagnostics for cable insulation assessment.
The instrument combines withstand testing with dissipation-factor measurements to help assess insulation condition and compare results over time. Automatic and manual test sequences, digital voltage/current metering and stored results support documented field testing. Integrated tan delta measurement avoids the need for a separate external TD instrument. Choose test voltage, waveform and accessories for the cable construction and applicable test procedure.
