Potential Transformer Model 468
Potential Transformers are encased in a thermoplastic case with the core and windings encapsulated in resin. Designed for line to line operation but may also be used in a line to neutral or line to ground configuration at 58% of rated voltage. All transformers with rated voltages 346V and below are ANSI C57.13 Group 1. All transformers rated 480V and 600V are Group 2.
