A current transformer (CT) is a type of transformer that is used to measure AC current. It produces an alternating current (AC) in its secondary which is proportional to the AC current in its primary. Current transformers, along with voltage or potential transformers are Instrument transformer. Current transformers are designed to provide a scaled-down replica of the current … [Read more...] about Current Transformer (CT) – Construction and Working Principle

Types of Gas Turbine Engines
For an individual generator that is rated above 1000 kW, and is to be used in the oil industry, it is usual practice to use a gas turbine as the driving machine (also called the prime mover). Below 1000 kW a diesel engine is normally preferred usually because it is an emergency generator running on diesel oil fuel.There are different types of gas turbine driven … [Read more...] about Types of Gas Turbine Engines
Corona Effect in Power System
What is Corona? The phenomenon of violet glow, hissing noise and production of ozone gas in an overhead transmission line is known as the corona. In this article, we will study what is corona, how the corona is formed in transmission lines, the advantages & disadvantages of corona and how can we reduce the corona effect. When an alternating potential difference … [Read more...] about Corona Effect in Power System
