What are the differences between a current transformer and a potential transformer?
Understand the Problem
The question is asking for a comparison between a current transformer and a potential transformer. This likely involves understanding their functions, how they are used in electrical systems, and their key differences.
Answer
CTs measure current, while PTs measure voltage. CTs step down high currents, and PTs step down high voltages.
The primary difference between a Current Transformer (CT) and a Potential Transformer (PT) is that a CT measures current, while a PT measures voltage. CTs step down high currents to lower, measurable values, whereas PTs step down high voltages.
Answer for screen readers
The primary difference between a Current Transformer (CT) and a Potential Transformer (PT) is that a CT measures current, while a PT measures voltage. CTs step down high currents to lower, measurable values, whereas PTs step down high voltages.
More Information
CTs are also Current transformers, and PTs can also be called Voltage transformers.
Tips
It can be easy to confuse the purpose of the devices. Just remember Current transformers measure current, and Potential transformers, measure potential (voltage).
