Grounding Transformers

Drive Isolation Low Efficiency

Grounding transformers are a critical component in electrical installations, especially where power generation through solar, wind or traditional generators occurs. A magnetic grounding device is a cost competitive method to provide “effective” grounding (Article 100 of NEC Code) in three-phase three-wire systems.

Hammond Power Solutions has been a valued supplier of these custom magnetics, typically in a zig-zag or autotransformer configuration.
