It was a campus placement where they had a requirement for a GET position. They were looking for students from an Electrical Engineering background. We were called to the Siemens plant, where we were initially instructed to take a written test. Due to the large number of applicants, this was quite easy and basic. After the test, shortlisted candidates were called for an interview.

In electrical plants, power is supplied and enters the plant via a meter that measures the voltage and current levels of the incoming electricity. Current Transformers (CTs) and Potential Transformers (PTs) are connected. Now, suppose one of them is not working. Can we use one of these transformers to get the value of the other parameter as well?
