Comparison of Systems Between KRISS and NRC to Evaluate the Performance Characteristics of A 400-kV Capacitive Voltage Divider

The Korea Research Institute of Standards and Science (KRISS) has established a reference 400-kV capacitive voltage divider for the purpose of calibrating industrial high-voltage measuring systems on site. In order to confirm the performance characteristics of the divider, a comparison of the calibration systems between KRISS and National Research Council Canada with the divider used as the transfer standard was conducted. This paper presents the comparison results and its analysis in obtaining the voltage-dependent performance characteristics of the reference 400-kV voltage divider over its entire range.
