What is a Potential Transformer (PT)?

Issue:
Definition of Potential Transformers (PTs)

Product Line:
LV Transformers

Environment:
Applies to Low Voltage Transformers by SquareD/Schneider Electric

Cause:
Potential Transformers are different from standard Control Transformers

Resolution:

A Potential Transformer (PT), or Voltage Transformer (VT) is an Instrument Transformer used for measuring voltage. It is specially designed to maintain an accurate voltage phase angle reference between the source and the Instrument Transformer`s output along w/ excellent voltage regulation to obtain accurate voltage measurements. When used with Current Transformers (CT), accurate power measurements can be made.
