For an EHV equipment for maintenance first it should be isolated and connected to ground because_____________?
Correct answer: D. both (B) and (C)
- A. to provide low impedance
- B. to discharge the charging capacitance to ground
- C. protection for operating personnel
- D. both (B) and (C)
Explanation
An isolated EHV apparatus may retain charge on its capacitance even after disconnection. Grounding discharges this stored energy and protects maintenance personnel from electric shock, so both statements apply.
