<p><P>PROBLEM TO BE SOLVED: To contrive cost down and utilize a space in an engine room effectively by a method wherein the number of set of isolation transformers is reduced by equipping a plurality of secondary windings electrically independent to each other in a secondary side. <P>SOLUTION: The isolation transformer (1) for inboard power supply is equipped in the secondary side with a plurality of secondary windings (4a, 4b, 4c, 4d) which ar independent electrically to each other, while a single primary winding (3) having a capacity substantially corresponding to the total capacity of the plurality of secondary windings (4a, 4b, 4c, 4d), is equipped in a primary side. Further, the plurality of secondary windings (4a, 4b, 4c, 4d) are equipped respectively with earth fault detecting means (5a, 5b, 5c, 5d) for independent series power supply circuits connected to each secondary windings. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
