PURPOSE:To provide a method for efficiently using contract power even when unbalance occurs between a load in phase A and that in phase B. CONSTITUTION:This method is for facilities supplied with power by a single- phase, three-wire distribution system. 200V lines on the contract breaker side are connected to both sides of primary winding between the breaker 2 and indoor wiring 3. 100V lines on the indoor wiring side are connected to both sides of secondary winding. Further, a transformer 4 for balanced load conversion wherein the neutral wire on the contract breaker side and that on the indoor wiring side are connected to the middle point of the secondary wiring, is placed in-between. |
