  In September 2014, the State Grid Fujian Electric Power Research Institute used the 900kw (450kWX2 parallel use) non-partial discharge variable frequency power system developed by Suzhou Huadian in the Dahu UHV substation to carry out the 1000kv main transformer induction withstand voltage and partial discharge test.

• 

  In October 2015, Suzhou Huadian customized a vehicle and a box of ultra-large capacity UHV main transformer induction withstand voltage and partial discharge test equipment for the State Grid Jiangsu Electric Power Research Institute to test at the UHV 1000kv Taizhou Station.
