Description

600-DMG1 CT Demagnetization Circuit

Many of you have seen a measured ratio test reading of a CT that was not what it should be: For example, a 200:5 CT that measured out to be 212:5 but passed the burden test. This is a magnetized CT. And what can you do about it? Either nothing or change out the CT. Now there is a 3rd option: The Spinlab Demag Circuit used in tandem with the Bird Dog Plus. Of the 32 failure modes of a meter circuit, magnetized CTs are by far the most common ones after installation errors. A magnetized CT can be caused by a lightning strike, ground fault, or open circuiting a CT. With this shoebox size device, you simply attach the duckbill connector to the phase of the test switch you want to demagnetize, turn the unit on, press the Demag button, and in less than 1 minute your CT will be demagnetized. It is that easy, and you don't have to take anything out of service! Never has increasing the accuracy of a CT-metered site been easier.
