Abstract
PURPOSE:To remove the mutual interference generated between the main and secondary circuits by a method wherein the independent transformer for instruments, using a rod-type core and a closed magnetic circuit core respectively, is assembled in a common container. CONSTITUTION:A closed magnetic circuit type core is used for a main core 12 because the main secondary circuit has a large burden and requires a high accuracy, and a main primary winding 13 and a main secondary winding 14 are formed. A rod type core is used for a subcore 15 because a subsecondary circuit has a small burden and a low accuracy is all right for its output, and the primary and the secondary windings 16 and 17 are performed. According to this constitution, the main core and the subcore can be formed into a suitable structure in accordance with the purpose of use and the main primary winding and the subprimary winding are formed independently. Therefore, even when a short-circuit occurred on a secondary circuit, the other secondary output voltage is almost in normal state, there exists sufficiently large voltage differential on the main and subsecondary output and the voltage differential is accurately detected by a voltage differential relay and the like, thereby enabling to sufficiently improve the trouble discriminating capability as well as to miniaturize the machine.
