HV-OWS-63 Oscillating Wave Test System (OWTS) for On-site PD Diagnostics of Cables

HV-OWS-63 Oscillating Wave Test System (OWTS) for On-site PD Diagnostics of Cables

Brief Description:

HV-OWS-63 Oscillating Wave Test System (OWTS) for On-site PD Diagnostics of 10KV Cables is an integrated partial discharge location and management system. Partial discharge test with DAC waves,Test frequency varies from 50Hz to hundreds of Hertz under damping AC voltage.

It simulates the running state of the cable by applying voltage, and can induce partial discharge and detect its intensity and location. It uses a hollow inductor in series with the tested cable, and charges its series circuit through a high-voltage DC source. When the charging voltage reaches a preset value, it closes the electronic switches connected in parallel at both ends of the power source, thereby forming a damping oscillation circuit, generating an oscillating voltage, and this oscillating voltage is used to excite the partial discharge at the insulation defect of the cable, and the quality of the cable insulation can be judged by detecting the partial discharge.
