Current and potential transformer
WebDefinition of potential transformers or voltage transformer. A potential transformer (PT) is a static device used to step down high voltages to measurable levels in order to facilitate measurement and controllability. Low voltages are easy to measure and can be used to operate protection relays. Image credit: Wordtwist.
