Abstract

The invention provides a method and a system for testing a current transformer. The system comprises a transformer calibration device, a PC and a calibration table top, wherein the calibration table top is provided with a current transformer to be tested and a test monitor screen. After the connection of the current transformer to be tested is finished on the calibration top, the PC sets a current transformer calibration proposal, downloads information on the current transformer from a marketing system and analyzes calibration parameters after the setting is finished; then the PC controls a calibration device to calibrate the current transformer to be calibrated automatically; after that the result of the current transformer calibration performed automatically by the calibration device under the control of the PC is acquired; and finally, the current transformer calibration result is transmitted to the marketing system to complete the test of the current transformer. The method and the system solve the problem that the prior method for testing the calibration of the current transformer is low in efficiency, and has the advantages of quick calibration, safety, reliability and the like.

Description

【Technical field】 [0001] The invention relates to the field of transformer testing, and provides a current transformer testing method and a system thereof. 【Background technique】 [0002] The current transformer is a metering device widely used in the power system. The performance of the current transformer is directly related to the reliability of the metering system. Unqualified current transformers will also affect the safe operation of the power system, so it must be checked test. The traditional verification method relies on manually raising the source, and then uses the transformer comparator to compare the difference and angle difference to test the transformer. However, this test method can only verify one transformer at a time, and the verification efficiency is relatively low. 【Content of invention】 [0003] In order to solve the technical problem of low efficiency of the current testing method for testing current transformers, the present invention provides a t...
