On the CT there will be a white dot that represents a polarity mark. This is used to connect to the correct polarity terminal on the device that the CT is connected to. Additional CT Transformers must be connected to the recording or monitoring device using the same polarity as the first CT.

What is the equipment required to do a CT polarity test?
You shouldn't need to perform a polarity test on a CT, as its terminals are normally identified with polarity markings.
How do you test polarity on a boiler?
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.
What is polarity test and continuity test?
a test to be conduct for find the phase...
What is the aim of doing polarity test on the transformer?
Knowing the polarity of transformers is important if they are to be connected in parallel.
How do you test reverse power trip?
There is a test swich which will change the polarity of the sensors........
Why test for polarity in welding?
Different material welds differently depending on polarity. There are also different types of welding rods, so polarity must be tested.
How do you identify the polarity of a diode when the tester is on diode scale?
To my own understanding, you will use multi-meter to test for the polarity
Why the polarity of transformer is important?
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
How can you do the polarity test of a switch?
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.
How do you test speaker wire polarity?
Observe polarity and touch a 1.5 volt battery to the terminals and note the direction the speaker cone moves.
When connecting a mains polarity test between the neutral and earth connections what should the reading be?
Infinity
Which supply has polarity AC or DC?
DC has polarity, while AC is constantly reversing in polarity.AnswerWhile the previous answer is quite correct in the sense of 'positive' and 'negative' charges, it's worth pointing out that 'polarity' has a second meaning in a.c. systems. In a.c., the term 'polarity' is used to describe the correct connection of the supply's line and neutral terminals. For example, with an Edison screw lamp holder, to remove the risk of shock, it's important that the line conductor is connected to the centre terminal, and the neutral conductor is connected to the outer terminal. If this has been done correctly, then we say that its 'polarity' is correct. Similarly, if the terminals of a socket outlet (receptacle) are connected the correct way around, then their 'polarity' is correct. Testing for the correct connections in an a.c. electrical system is called a 'polarity test'.
