POWER FOR CANTERBURY.

NEW GENERATING SET. A SUCCESSFUL TEST. , CHRISTCHURCH, July 11 Anxiety as to the supply of power for Canterbury from Lake Coleridge has been allayed as the result of the successful test- J ing of the No. 7 generating set, the capacity of which is 7500k\v. The new; generator was synchronised at 3.15 p.m. on Friday and carried about 500 kw of the Christchurch load. On Saturday the new set carried approximately 2000 kw of the city load between 10 a m. and 4 p.m. Some small adjustments to the governor will require to be made before the set can be put into regular service. These will be completed by the middle of the present week. Advantage was taken of the filling of the new tunnel to open a cross drive between the new surge onamber and the old one, thus raising the level of the water in the old surge chamber and automatically increasing the generating capacity of the 12,000 kw set, which has been limited by the pressure available fropi No. 1 tunnel. No. 7 generator at Coleridge is the largest individual set operating in the Dominion at present, but will be eclipsed by the big sets to be installed in the North Island schemes.
