It includes insights on installation, testing, troubleshooting, and modern innovations like digital CTs and Rogowski coils. Industry professionals can find technical discussions, case studies, and comparisons on how CTs enhance power monitoring, protection systems, and energy efficiency in industrial and smart grid applications.
The current transformer is a kind of transformer that steps down currents. From the name “current transformer,” we can understand that it deals with current. The available instruments for measuring and protection purposes in the market are of a few amperes range. The ammeters, energy meters, wattmeters, and various protection relays are rated for only … Read more
When it comes to high-voltage power systems, current transformers (CTs) play a critical role in measurement and protection. CTs come in two main designs—Live Tank and Dead Tank? While both serve the same fundamental purpose, they differ significantly in construction. The main differences between a live tank and a dead tank current transformer (CT) primarily … Read more
A Comprehensive Analysis of Nanocrystalline Core A critical component of a CT is its magnetic core, which significantly influences its performance, accuracy, and efficiency. Accuracy is the most essential property of a current transformer. Traditionally, Cold-Rolled Grain-Oriented (CRGO) silicon steel has been the material of choice for these cores. Nowadays, a superior alternative is available … Read more
