付変流器。In a current transformer in which a secondary winding and a test winding are distributed around an annular core, the test winding is partially drawn out as two windings with different numbers of turns, and each terminal is connected to a plurality of windings. Connect to the electromagnetic and manual switchgear terminals that have contacts, interlock the operation of each contact so that the two test windings separated above can be connected in series and parallel, and insert the manual switchgear into the test side. In this case, the two windings are connected in series to provide a constant current transformation ratio with the secondary winding, and when the operation side is turned on, one terminal of each of the two windings is connected directly in parallel. connection,
A current transformer with a test winding, characterized in that a protection system is provided when a secondary circuit is opened, which is connected in parallel between other terminals via a non-linear resistor.
