Dry-type zig zag grounding transformers are another example of Reliable Custom Transformers being built by Acutran.
Neutral grounding dry-type transformers are special purpose transformers that provide a grounding path for a delta connection or an ungrounded wye.
Generally used to protect an isolated 3-phase system in the event of a line-to-ground fault, grounding transformers provide a lower impedance path-to-ground for ground faults which shields the non-faulted phases from voltage spikes.
Neutral grounding transformer units aren’t typically used in commercial or industrial applications because they do cost a little more than your conventional dry-type transformer. But if you need a ground – this is the way to go.
