Question
Chapter 6, Problem 1RQ
To determine
The differences in connection between the primary winding of the voltage transformer and primary winding of the current transformer.
Expert Solution & Answer
Explanation of Solution
The differences in the connection between the primary winding of the voltage transformer and primary winding of the current transformer are as mentioned below:
Primary winding of voltage transformer | Primary winding of current transformer |
The primary winding of the voltage transformer has large number of turns. | The primary winding of the current transformer has less number of turns. |
The primary winding of the voltage transformer carries the voltage which is to be measured. | The primary winding of the voltage transformer carries the current which is to be measured. |
