The trolley circuit is fed from the power house andfour synchronous-converter substations which arespaced about 20 miles apart. A fifth substation is beingbuilt at a junction where the load is especially will reduce the average distance between substa-tions to about 15 miles. The substations are connectedwith the generating station through a 22,000-volt,three-phase transmission system. There is also a dupli-cate transmission system carrying three-phase, 22,000-volt, 25-cycle current from the power house at Fraser,37 miles north to Fort
