Abstract :
The paper presents an absolute measurement method of determining the voltage coefficient(VC) of high voltage capacitive dividers(CVD) by serial summation of voltage transformers. Under a series of double-voltages, by successively comparing a CVD with a full-insulated transformer, a semi-insulated transformer and their series, the VC of the CVD were gotten. The method was verified by using two voltage transformers rated with (110/√3 )kV/(100/√3)V in series.
