What are the definitions of Current Transformers (CT) and Potential Transformers (PT), and what are their uses?

Question

Accepted Answer

CTs and PTs are devices used in electrical systems to measure current and voltage respectively.

Current Transformers (CTs) are used to measure current in electrical circuits by stepping down the current to a safe level for measurement.
Potential Transformers (PTs) are used to measure voltage in electrical circuits by stepping down the voltage to a safe level for measurement.
CTs and PTs are commonly used in power distribution systems to provide accurate measurements for protection and control purposes.
CTs and PTs are essential components in metering systems to accurately measure energy consumption.
CTs and PTs are designed to accurately transform current and voltage levels without introducing significant errors.
