Leakage detection system UHV-505

sparklaserwireless

The UHV-505 is a portable, all-in-one on-site cable diagnostic system that performs non-destructive testing using Damped AC Voltage (DAC) up to 30 kV. It combines partial discharge (PD) detection and dielectric loss measurement to evaluate insulation defects and ageing, and supports cloud upload for remote analysis and predictive maintenance.
