Abstract

PURPOSE: To make it possible to use the conventional differential relay without alteration, by providing two iron cores which are each provided with one or more low voltage windings with a common high voltage winding, and by suing one low voltage winding of one iron core as main winding and one low voltage winding of the other iron core as secondary winding, and thereby increasing the voltage of the secondary winding.
CONSTITUTION: Iron core 14 is provided with main winding 2, and iron core 24 is ptrovided with secondary winding 3. These iron cores are placed one on top of the other and are provided with common primary winding 1, and thereby a transformer for use in parent-and-child type meters is formed. By this construction, the voltage of the secondary winding becomes large when the main winding is short-circuited, so that the conventional differential relay can be used without alteration.
