Potential Transformer (PT)

Potential transformers are used to measure current and voltage circulating in electrical power systems. They are designed to control circuitry of high voltages by making use of a highly accurate transformation ratio between magnitude and phase. Potential transformers can also be used to step down the system voltage to a safe value which can be fed to low ratings meters and relays

 
Standards
