Discussion
Which of the following is NOT a type of power system protective scheme?
Answer: D
The common protective schemes in a power system are over current protection, distance (impedance) protection, differential protection, carrier-current (pilot) protection and earth fault protection. Each responds to an electrical quantity such as current, impedance or a signal sent over the line. Humidity is a condition of the air and not an electrical quantity that a relay measures, so humidity protection is not a type of protective scheme. The answer is option D.
