ABSTRACT: Capacitor voltage transformer (CVT), which is with
simple structure, convenient maintenance, functional diversity and high impact
pressure strength, is widely used. And its capacitance and dielectric loss
Angle measurement is an important test on testing the insulation of the
equipment. This paper is mainly to introduce and discuss one of the CVT test
methods——the “self excitation method”, combined with the actual situation encountered
in the work, sums up and expounds the maintenance of CVT and preventive test of
influence factors.
