Overview
30kva 3 phases earthing transformer manufacturers ZIGZAG transformer
Product Description
Grounding Transformers are designed for providing an artificial neutral point for ungrounded three phase power systems. During the line-to-ground faults, grounding transformers provide an easy path to ground faults to limit the fault currents and transient over voltages.
