How Higher Q Values Reduce Loss in Coil Windings In electrical engineering, the quality factor, or Q value, of a coil is a crucial indicator of its efficiency and performance. The Q value represents the ratio of the inductance to the equivalent circuit loss resistance at a specific AC frequency. A higher Q value indicates…
The wiring method of the current transformer is not very complicated, there are only four wiring forms. The four types of wiring will be listed below. Transformer The first is the wiring method of a single current transformer. Under the condition of only single-phase current, it is suitable to measure one-phase current or three-phase load…
The safe operation and management of transformers is the key to everyone’s daily work. Based on the experience exchanges on the analysis of abnormal operation conditions and common problems of transformers, it will be helpful to immediately and accurately distinguish the causes and characteristics of common faults, and take immediate measures to ensure The safe…
Filtering power capacitors, common mode inductors, and magnetic beads are common shadows in the power supply circuit of EMC design schemes, and they are also the three major artifacts for solving interference signals. Regarding the effects of these three in the power circuit, I firmly believe that many technical engineers do not understand. The content…
Split core current transformer, as its name implies, is a current transformer that can be opened and closed on the primary circuit (the side of the measured current circuit, usually a cable or parent card), and is a secondary device by sensing the current on the primary circuit Take measurements or protect relays. …
The general mutual-inductance watt-hour meter and the high-voltage watt-hour meter of the three-phase watt-hour meter must be connected to a current transformer or a voltage transformer. This article mainly introduces you in detail what are voltage transformers and current transformers and What is the difference between these two transformers. 1. Voltage transformer The working principle…
