Question 1 of 27070

Q

To determine if a stator coil on a AC generator is grounded, you should use a/an __________.

🔍 Key Concepts

• Insulation resistance testing for electrical equipment • Difference between measuring current, voltage, and insulation resistance • Typical instrument used to check for grounds or leakage on generator windings

💭 Think About

• Ask yourself: when checking if a winding is grounded, are you trying to see normal operating values, or are you testing the condition of the insulation? • Which instrument applies a higher DC test voltage to see if current leaks to ground through bad insulation? • Which of these tools would NOT normally be used as a permanent panel meter, but as a specialized test set?

✅ Before You Answer

• Identify which device is specifically designed to measure very high resistance (in megohms) to ground • Eliminate instruments that only read current in amperes or voltage in volts during normal operation • Recall which device is commonly used for insulation and ground-fault tests on motors and generators
