When we talk about voltage regulation we are looking at how good a transformer is at keeping its secondary voltage steady even when the load changes. Sometimes the output voltage we get from the secondary side is not exactly what we were expecting and that is where voltage regulation comes into play. Now when you […]
Explained: Three Phase Transformers and Calculations
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
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
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
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
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 […]
