🔍 Key Concepts

• Megohmmeter (megger) readings represent insulation resistance between conductors and ground • Typical readings: very high resistance = good insulation, very low resistance = poor or grounded insulation • How a megohmmeter scale usually displays zero vs infinity and what each physically means

💭 Think About

• If a cable is truly grounded, is the resistance between the conductor and ground very high or very low? How would that look on a megohmmeter scale? • Think about what an open circuit looks like on a megohmmeter compared to a short circuit or ground fault. • Which answer choice best matches a condition where current can easily flow to ground with almost no resistance?

✅ Before You Answer

• Clarify which side of the megohmmeter scale represents no continuity (open circuit) and which side represents full continuity (short/ground). • Visualize the meter’s scale: what reading would you expect when the insulation is completely broken down to ground? • Make sure you distinguish between steady readings and unsteady or fluctuating readings and what each usually indicates.
