Abstract

HVDC electronic voltage transformer is the important equipment to measure the voltage of the HVDC system

so as to realize the reliable monitoring of HVDC voltage

its insulation performance is related to the safe and stable operation of HVDC transmission system. This paper introduces the principle

structure and parameter of the ± 1 100 kV UHVDC electronic voltage transformer. First through theoretical analysis to know the external insulation and radial insulation

then combined finite element to verify the insulation performance of transformer. The analysis shows that the insulation characteristics meet the needs of transformer long-term reliability.
