The 468 Potential Transformer is designed for power monitoring or metering applications. It is operated line-to-line but may also be operated line-to-ground or line-to-neutral at a reduced voltage (58% of rated volts). The core and windings are completely encased in a thermoplastic shell and filled with a resin compound. These transformers are suitable for indoor use only. The 468 is ideal for use as an input to power monitors that require a 120VAC input voltage.
