Live Tank vs Dead Tank Current Transformers

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

Nanocrystalline Core in Instrument Transformers

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

Accuracy Limit Factor

Current transformers (CTs) play a crucial role in power systems, especially in protection and metering applications. Among the key parameters that define their performance is the Accuracy Limit Factor (ALF). This article provides an in-depth understanding of the ALF, its significance, and its impact on the reliable operation of protection systems. What is Accuracy Limit … Read more
