Abstract

Very Low Frequency (VLF) high voltage measuring system including the resistive high-voltage divider has been designed, developed and implemented from DC to 1 Hz up to 120 kV. The divider consists of three modules stacked on top of each other. The characterization of VLF high voltage measuring system has been performed by the calibration of the scale factor with the precision HVDC measuring system directly to determine the performance of it. The expanded uncertainty value of VLF high voltage measuring system was determined as 0.05% which meets the requirement of IEC 60060-2: 2010. This measuring system has been currently used in TUBİTAK UME (National Metrology Institute of Turkey) as a reference measuring system for the calibration of VLF high voltage test devices in-house and on-site.
