How to use our VLF-80KV AC Hipot Tester to test power cables of different voltage levels?
Publish Time: 2023-09-20 Origin: Site
Our VLF-80KV AC Hipot Tester is used to test power cables 35KV and below. It consists of two boosters(50kV+30kV), one controller and one standard capacitor.
1) When carrying out 10KV cable test, one-phase test is strongly suggested. The voltage shall be 18KV and the frequency shall be 0.1Hz、0.05Hz、0.02Hz、0.01Hz. The manual said load capacity is the theoretical value, the scene 10KV cable length can reach 3-8 km.
2) When carrying out 35KV cable test, one-phase test is strongly suggested. Voltage is set to 60KV (General Requirements)-78KV (according to the rules needed) and the frequency is set to 0.1Hz, 0.05Hz,0.02Hz and 0.01Hz. The manual said load capacity is the theoretical value, the scene 35KV cable length can reach 3-5 km.
3) In case the cable is too short(less than 500 meters), the capacitance of the test object is smaller than 0.1μF and the pressure cannot be normally boosted, please connect 0.1μF high-voltage capacitance in parallel way.
