Instrument Transformer Tests Besides the obvious doo-dah’s mentioned above, such as verifying that CTs are neither shorted nor open-circuited and the like, what tests should be performed? Part of the answer depends on whether it is a routine maintenance test interval, a major maintenance test interval, or acceptance testing. During ac-ceptance testing, all aspects and characteristics of the Polarity test is to confirm the polarity marking on the CT primary and secondary and verify it is matching with drawing. More ever it is giving an idea, how to connect the secondaries to make the protection (like directional, differential) and metering function properly. Isolate CT secondary from
