In this article, we are going to discuss the dead tank CT or dead tank current transformer, commonly referred to as a dead tank CT. Dead tank current transformers are not popular for very high-voltage systems like 220 kV and above. Utilities often use dead tank CTs in 33 kV systems. They prefer this design … Read more
Cause of Voltage Regulation Every electrical source has some internal or inherent impedance. It may be a battery, a transmission line, a power transformer, or any other device that can supply electric power. Due to this inherent impedance, there is always a voltage drop in that system. When we measure the voltage across the open … Read more
A power transformer has high cost, large size, and complex design. So, identifying defects at the final stage of manufacturing can lead to significant delays, expenses, and operational challenges. Therefore, standards always recommend performing different tests and inspections during various stages of manufacturing. That means the standards always prefer to perform stage inspections of a … Read more
