Most megger testers provide a voltage range from?

• A. 0 to 50 volts
• B. 500 to 1000 volts
• C. 0 to 500 volts
• D. 500 to 5000 volts

Answer: (D)

Megger testers stress insulation by applying a high DC voltage and measuring leakage resistance, so having a broad output range is essential. Most units are designed to cover a wide span—from roughly a few hundred volts up to several kilovolts—which lets you test both low‑voltage equipment and higher‑voltage gear like motors and transformers. A lower range wouldn’t reliably reveal insulation weaknesses, while too high a voltage can be unsafe or unnecessary for small equipment. That broad, high‑voltage capability is why the typical range is described as starting in the hundreds and extending into the kilovolt range.
