ACSOON AC Power Supply for Transformer PD Test

ACSOON 300kVA three phase AC Power Supply completed the fabrication and test on November 2021, which is successfully delivered at place to customer's site in Bizkaia Spain. The feedback of the equipment was positive after a period of performance with the test of transformer partial discharge test. The partial discharge is less than 10pc and with completely protection of over/under voltage, short circuit and over current.

The power supply itself adopts high frequency SPWM modulation, MOS/IGBT Rectifier and Inverter technology and complied with IEC standard for the 40hz - 400Hz Electric Power Characteristics. It can output very pure sine wave form in VTHD<2%. Output volt stability in line regulation ≤±1％FS and Output volt stability in load regulation ≤±1％FS

The AC Power Supply was coming with filters, which is more helpful and effective during the transformer PD test. It could heavily reduce the harmonic from input and improve the quality of AC Power Source. To deliver pure sinewave AC Power is very crucial to loads and application in LV lab.
