You shouldn't need to perform a polarity test on a CT, as its terminals are normally identified with polarity markings.
To test polarity on a boiler set the meter to loop, touch the two leads together, and it will buzz or read as "000". This will show you the polarity as well as test for continuity.
Knowing the polarity of transformers is important if they are to be connected in parallel.
Different material welds differently depending on polarity. There are also different types of welding rods, so polarity must be tested.
A 'polarity test', as it applies to a switch, is performed to confirm that the switch is located in the line conductor and not in the neutral conductor.

a test to be conduct for find the phase...

There is a test swich which will change the polarity of the sensors........

a polarity test is a test which use to check the polarity of tranformer.the rision of this test to running the two or more transformer in parallel.like bettry situation or to fin the terminals

if montoux test is positive
Observe polarity and touch a 1.5 volt battery to the terminals and note the direction the speaker cone moves.
looking for coliforms!
A test carried out for testing liver metastasis. is the test required in case of confirmed metastates?
