Measurement of high voltages is possible by the potential transformers.
2.
Voltage transformers ( VT ), also called potential transformers ( PT ), are a parallel connected type of instrument transformer.
3.
Current transformers, together with voltage transformers ( VTs ) or potential transformers ( PTs ), which are designed for measurement, are known as "'instrument transformers " '.
4.
Since the invention of the first constant constant-potential transformer transformer in 1885, transformers have become essential for the RF transformers less than a cubic centimeter in volume to units interconnecting the power grid weighing hundreds of tons.
