The production of 500kV voltage error test platform and 500kV current error test container manufactured by Shandong Taikai Instrument Transformer Co., Ltd for Tibet Electric Power Research Institute has been completed. The error test of CT & PT at Markam 500kV substation in Tibet was also completed successfully. 

500kV voltage test platform adopts series resonant boost, which has the advantages of low height, light weight, variable ratio, high integration, and convenient on-site lifting. 

500kV current error test container has series parallel functions of strong current generator. The generator and standard current transformer are arranged in the container test room. Testers conduct tests in the room, which greatly improves the test efficiency and improves the on-site working environment of the test personnel.  

The above two sets of products have adopted high-altitude, high-precision, bump-proof design, pass the error test of Markam 500kV substation, and contribute to the transmission of power in the networking project in Tibet.
