In brief – Power autotransformers

Autotransformers are a special type of power transformers that feature a single winding wound onto a laminated core. They are used to either step up or step down the voltage. They’re similar to two-winding transformers. However, their differences lie in how the primary and secondary winding are interrelated. Types of autotransformer Autotransformers are broadly categorized into two …

Choosing a Current or Potential Transformer

When measuring AC currents and voltages of high magnitude, we often take for granted clamp and amp meters. However, the question is, how are these portable measuring instruments able to step down the magnitude to a standard range instrument? How can the original magnitude be determined by just multiplying the result with the transformation ratio? …
