My family and I will be in Kauai from 12/4-13 and the early weather reports look particularly stormy throughout next week. Is everyone else seeing the same thing?
Transformer Vault Construction. Transformer vaults are the concrete holding areas for the large transformers reducing high voltage power down to the lower voltage power for the area being served. The Robert Henry Corporations has over ten years or experience constructing transformer vaults and power substations.
A transformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction. 1  A varying current in the transformer's primary winding creates a varying magnetic flux in the core and a varying magnetic field impinging on the secondary winding.
