On May 10, 2019, 200kV AC high-voltage standard system produced by Shandong Taikai Instrument Transformer Co., Ltd. successfully completed various performance tests at National Metrology Center Laboratory in Singapore, passed the Center experts' acceptance and got highly recognition.

The performance index of the system remains unchanged after 5,000 kilometers transportation by land and sea. It meets the power frequency withstand voltage of 240kV/1 min, the voltage stability is controlled within 30ppm, accuracy level up to 0.02, and meanwhile the error variation of standard voltage transformer is less than 1/4 of its error limits.

The acceptance of the system has improved the business level of Singapore National Metrology Center, doubled the maximum output voltage of power frequency voltage boosting device, and improved the highest accuracy of standard voltage transformer by two levels. It also enhanced the communication between our company and overseas high-voltage metrology center, and promoted the influence of Taikai brand in the international HV standard measurement field.
