Medium Voltage Potential Transformer (Model PTG5)


Contact AYA Instruments for a Quote.

The PTG5 series of potential transformers (PTs) are designed for high accuracy medium voltage measurements. The purpose of this PT is to proportionally reduce the primary voltage to a level that is within the input range of a standard meter, transducer, or controller. These PTs can be used together with current transformers (CTs) for the monitoring of power and energy. Flex-Core has several of the more common models in stock.
