To detect an over - current fault condition, the most reliable method is to connect a_____________?
Correct answer: C. Current sensor in series with IGBT
- A. Current sensor across IGBT
- B. Voltage sensor across IGBT
- C. Current sensor in series with IGBT
- D. Voltage sensor in series with IGBT
Explanation
A current sensor must be placed in series with the IGBT so that the fault current flows through it and can be measured directly. A voltage sensor across the device detects voltage stress, not over-current itself.
