This specification is applicable to the calibration of transformer loss measurement systems (hereinafter referred to as measurement systems) with a rated frequency of 50Hz and a voltage level of (10~1000) kV. The measuring system is a device used to measure the no-load loss and load loss of the transformer. It consists of a measuring voltage transformer (voltage divider), a measuring current transformer, a measuring instrument, a gear adjustment unit and a connecting cable.
