Testovací zařízení KV Hipot Transformer použité v projektu skladování energie

KV Hipot Power Equipment Co., Ltd.’s three-phase DC resistance tester (20A) and three-phase turns ratio tester were used for electrical testing of the main transformer at the 220 kV step-up substation, supporting winding resistance measurement and turns ratio verification during the on-site commissioning phase.

What VLF Hipot Test Voltage Should You Use for a 33 kV Cable?

There is no universal test voltage for every 33 kV cable. If the nameplate is 19/33 (36) kV and the approved procedure specifies 3U₀ sinusoidal VLF, the calculated level is 57 kV RMS, or approximately 81 kV peak. An 18/30 (36) kV cable would produce a different result.

Jaká je zkušební napětí pro testování kabelů střední napětí podle standardů SEC?

Testování s velmi nízkou frekvencí (VLF) pro všechny kabely středního napětí během uvedení do provozu a diagnostiky. Požadavky na schválení SEC jsou obecně formulovány na základě principů mezinárodních norem IEEE 400.2 a IEC 60502-2.
