Wireless High Voltage Phasing Tester

121;344;6b9f0a72bd70e55fa9dc91e46b30c6aba7ee57b3
The wireless high voltage phasing tester (two probe tester)  will check the 3 phase HV lines are of in-phase, out-of phase and phase angle measurements. The wireless technique will assist in high voltage isolation between the HV sensor unit and the detection display unit for better visualization, HV safety and high raise height OH lines for high voltage levels up to 765kV.
