Transformer For Dunedin
A 15-ton voltage regulating transformer, one of the largest in New Zealand, was brought through the Christ-church-Lyttelton road tunnel on Tuesday after being unloaded from the inter-island ferry Wahine. The transformer was built by Turnbull and Jones Ltd at Petone and will be delivered to the Dunedin City Council to join a similar machine sent six weeks ago. Partially stripped for travelling, the transformer will weigh more than 24 tons when assembled at the council’s substation at Wakari. It will automatically regulate power from the national grid so that Dunedin will receive a constant 33,000 volts regardless of fluctuations in supply or heavy loads.
The tanks of the transformer are filled with nitrogen, for travelling, to avoid any oxidation and to ensure that the tanks are clean when the oil is put in at installation. The order for the transformer was secured by Turnbull and Jones on an open tender against world-wide competition; 3500 man hours were spent in assembling it.
