🔍 Key Concepts

• Insulation resistance testing with a megger (insulation tester) on high‑voltage equipment • Common rule-of-thumb formulas that relate system voltage (kV) to minimum acceptable insulation resistance in megohms • Why safety margins increase as the operating voltage of the motor increases

💭 Think About

• Is there a simple “1 megohm per kV” or “(kV + constant) megohms” type guideline that is often used for minimum insulation resistance on motors and cables? • For a 3.3 kV motor, if you apply that guideline, which of the choices comes closest to or just above that calculated minimum value? • Which option represents a realistic minimum (not too low for safety, but not excessively high beyond common standards)?

✅ Before You Answer

• Confirm what industry rule-of-thumb is commonly used for minimum insulation resistance in megohms as a function of kV rating • Make sure the chosen value is at least equal to or higher than the calculated minimum from that rule • Eliminate answers that would obviously provide too little safety margin for a 3.3 kV motor’s insulation.
