HV Exit Exam • Set 5 Question 11 of 30

A switching surge in a high-voltage electrical network is defined as a:

✓

Direct Answer

Option C: Short-duration transient overvoltage produced by switching operations

Switching surges are short-duration (microseconds to milliseconds) damped oscillatory overvoltages caused by breaker opening/closing, interrupting inductive currents, or fault clearing.

All Options

Continuous steady-state high-voltage DC

Power frequency harmonic voltage

Short-duration transient overvoltage produced by switching operations (Correct Answer)

Permanent neutral shift

Detailed Explanation & Context

Switching surges are short-duration (microseconds to milliseconds) damped oscillatory overvoltages caused by breaker opening/closing, interrupting inductive currents, or fault clearing.

Relevant Framework: STCW 2010 Manila Amendments • DG Shipping E-Learning & Exit Exam Standards • High Voltage Safety Officer & Switchgear Operations (HV).
