Model# PTG5 | 15KV Class

Model# PTG5 Medium Voltage Potential Transformer

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.
