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…
DetailsCurrent transformers (CTs) are the silent workhorses in power systems, responsible for accurate current measurement and safe relay protection. But not all CTs are made the same. A common question that puzzles many engineers and electricians is: What’s the difference between a bus-type current transformer and a pillar-type current transformer? At first glance, these terms…
DetailsThe 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…
DetailsTransformers 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…
DetailsYou should be clear about the scope of inductance in the power circuit. Since the inductance is mostly not stable during the entire working period of the components, it is particularly important to grasp the scope of the effective value. For inductors used in power switching applications, the overall goal of allowable harmonic distortion current…
DetailsThe main uses of RF inductors are diverse, and can be used in various structural features to consider performance testing schemes for special applications. Matching, resonators and choke coils are the main common uses of inductors in RF power circuits. Matching includes removing the characteristic impedance mismatch and minimizing the reflective surface and loss of…
