<p><P>PROBLEM TO BE SOLVED: To resolve the problem wherein capacity and weight of a power receiving power transformer used for a high voltage power receiving installation are large, the transformer is too large and redundant and full load loss is enlarged, thus causing a cost rise. <P>SOLUTION: In the high voltage power receiving installation where in a three-phase AC transformer and a balancer are integrated or a single pole type high voltage power receiving installation, a voltage to ground is 115V, harmonics causing false report is restrained, secondary side wiring is reduced and ohmic loss is reduced. Consequently, a light and miniaturized space-saving power transformer is realized, an installation space such as a cubicle is cut, and cost reduction is realized. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
