Other Transformers for Power Grid Infrastructure

Drive Isolation Low Efficiency

Grounding transformers

HPS grounding transformers provide a low impedance path to ground to keep the system’s neutral at or near ground level. This provides several benefits including providing a ground fault path during line-to-ground faults, limiting the size of transient voltages and allowing the connection of phase to neutral loads.
