Explained: Three Phase Transformers and Calculations

December 28, 2024 by Admin-EF Leave a Comment

A 3-Phase electricity is basically a method we use to create and send electric power over really long distances so that our offices and industries can use it. In this setup we deal with three-phase voltages and currents which we can adjust either increase or decrease, using three-phase transformers. These transformers are pretty cool because […]

Current Transformer Explained with Calculations

December 24, 2024 by Admin-EF Leave a Comment

We use a Current Transformer (C.T.) as an “instrument transformer.” It creates an alternating current in its secondary winding that matches the current in its primary winding. Current transformers lower high voltage currents to safer levels. They help us monitor the actual electrical current in an AC transmission line using a standard ammeter. The way […]

Autotransformer Working and Calculations Explained

December 16, 2024 by Admin-EF Leave a Comment

An autotransformer is not like the traditional voltage transformer. Normally a voltage transformer has two distinct windings. These windings are called the primary and the secondary. But with an autotransformer things are a bit different because it only has one single winding that actually does the job of both the primary and the secondary. Now […]

Understanding Transformers with Multiple Winding

December 14, 2024 by Admin-EF Leave a Comment

Talking about Multiple Winding Transformers these are a type of transformer that usually has one primary winding and then two or more secondary windings. The cool thing about these transformers is that they can have multiple windings either on the primary side or the secondary side. Because of this feature we often call them Multiple […]

Understanding Loading of Transformer with Calculations

December 13, 2024 by Admin-EF Leave a Comment

In the earlier lessons we had about transformers, we kind of assumed that these devices were flawless. This means we thought their windings did not experience any core losses or copper losses at all. But when we actually use a transformer “on-load” we have to face the reality that there are always going to be […]

Electrical Transformer Working: Explained with Formulas

December 7, 2024 by Admin-EF Leave a Comment

In this tutorial about transformers I will explain the basics in simple terms. As we know transformers can work without any moving parts inside and it is mainly used to change voltage levels so that we can transfer energy from one circuit to another through electromagnetic induction. We use alternating current (AC) in our homes […]
