Abstract

This work solves a design of measurement current transformer for encapsulated substation 400kV with parameters 2000A/5A/1A/1A with class accuracy of 0,5. The work is gradually elaborated description of embodiments of encapsulated substation and then compared with conventional outdoor substations. There are described the properties of the electronegative gas. In this work are explained basic concepts of measuring current transformers, the issue of errors and their solutions. The main part of the work described process design of measurement current transformer.
