The safe operation and management of transformers is the focus of everyone’s daily work. Based on the experience exchange of abnormal operation conditions and common problems analysis of transformers, it will be helpful to immediately and accurately determine the causes and characteristics of common faults, and take immediate measures to ensure The safe operation of…
What is the current transformer calibrator Transformer The current transformer calibrator is used for high-voltage electric energy measurement in power generation and substations. It uses detection technology and large-scale electronic design. It solves the problems of high intensity and complicated actual operation on the current transformer and voltage transformer calibration site. Principle of current transformer…
The power of a three-phase meter is mainly determined by the current specification and model of the three-phase meter and the voltage required for on-site work. If it is a DC power meter, the power P=I currentU working voltage3, let us give an example below. Transformer If the current specification and model of a three-phase…
Transformers exist in two forms in the industrial field, that is current transformer and voltage or potential transformers, and their main role are for the measurement or protection, and automatic control, etc. They are windly used in the power grid of the network reconstruction projects. In general, most of the occasions of using electricity will…
One-piece inductors are also called: Molded inductors include magnets and windings themselves. Surface-mount inductors. The key difference from general output power control inductors depends on the fact that one-piece inductors have a winding first, and then The metal is formed by die-casting of powdered and filled aluminum with magnetic material, and the leads are drawn…
Zero-sequence current transformers are also called residual current transformers, ground current transformers or leakage current transformers. They are usually used in power fire protection equipment. When the power system generates zero-sequence grounding current, it is used in conjunction with the relay protection device for pre-protection or monitor. The basic principle of the zero sequence current…
