Description

technical field

[0001] The invention relates to the field of electric equipment detection, in particular to a program-controlled current transformer automatic verification system. Background technique

[0002] According to the JJG313-2010 "Current Transformer for Measuring" verification regulations: the 0.05-0.01 class current transformer used as a standard device must be verified every two years, and every change must be verified during the verification. The current transformer used as a standard device generally has a transformation ratio range of 5-2000 / 5, 1A, and an accuracy level of 0.05-0.01. The transformation ratio range is wide and the grade requirements are different. In the actual verification, there will be wrong wiring. , the work efficiency is low; moreover, in the verification process of different transformation ratios of the same standard instrument, because the operator of each connection is not necessarily the same, the connection contact of different trans...
