整体检定现场电流互感器检定装置的探讨
Research on the Whole Certification of the Locale Device Used to Test Current Transformer
摘要
Abstract
This paper analyzes the mathematical models of various types of locale current transformer calibration equipments, and explores issues related to the whole calibration. The requirements of the standard device are proposed on the whole calibration: the standard device should be applied to all types of calibration equipments, I.e. The standard device is both the current transformer and the voltage transformer, the secondary burden is no-load or the resistance of connection wires is 0.02Ω, the accuracy class is not lower than 0.01S, in the case of maximum permeability, the one-turn inductive e.m.f should not be less than 0.06V. In the whole calibration, the working conditions should be as closely as possible the actual working conditions of locale current transformer, I.e. The standard device should be used to work under no compensation and turn compensation. Thus, the whole calibration is accurate and reliable.关键词
