- The Olsun Advantage – Encapsulated Transformers
If you have a delta or ungrounded wye connected distribution system application where a neutral ground path is required via a custom neutral grounding transformer or ground isolation transformer…Olsun Electrics can do that!
Olsun can design, manufacture and supply a dry-type neutral grounding transformer, or ground isolation transformer, in either a Zig Zag or a Two Winding configuration for your particular application.
Zig Zag Transformer Configuration Two Winding Configuration
A properly designed and installed grounding transformer will protect an isolated three phase system in the event of a line-to-ground fault by providing a low impedance path to ground for ground fault currents to flow while prohibiting voltage rise in the un-faulted phases and accommodating the connection of phase-to-neutral loads if required.
To provide a quotation or to design and manufacture your required ground isolation transformer, Olsun Electrics requires certain application and system data.
NOTE! You may have noticed that “kVA” is not one of the parameters requested. Grounding isolation transformers are sometimes referenced by a kVA, but technically, they should not be so referenced unless they are providing auxiliary power in some way.
A neutral grounding transformer in the conventional sense is to be “labeled” based on the system continuous current and fault current it is designed to carry.
