HV Exit Exam • Set 4 Question 12 of 30

Which of the following measuring instruments is used for measuring high-frequency AC surge and impulse peak voltages?

✓

Direct Answer

Option A: Peak voltmeter

Peak voltmeters (using diode rectifiers and storage capacitors or digital peak detectors) accurately measure the maximum peak crest value of high-frequency and impulse waveforms.

All Options

Peak voltmeter (Correct Answer)

Moving iron voltmeter

Dynamometer voltmeter

Thermocouple ammeter

Detailed Explanation & Context

Peak voltmeters (using diode rectifiers and storage capacitors or digital peak detectors) accurately measure the maximum peak crest value of high-frequency and impulse waveforms.

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