摘要
Abstract
Substation high-voltage transformer is usually tested in field, for the large bulk and high voltage makes it difficult to be taken to laboratory for test. The problem of error test of 500kV CT in field in Henan province is discussed. The theory of CT error test is introduced via error characteristics simulation. The method of CT error tester takes use of frequency conversion, digital processing methods and software anti-interference. Test results of CT error tester in lab and field prove the stabilization and reliability and show that it meets the test requirement of CT of 500kV substation so as to improve the efficiency of CT error test in field.关键词
