FAQ
Q： Which meter measures insulation resistance?
A： The ideal digital insulation resistance tester measures the insulation resistance of electrical systems and assesses the performance of equipment, cables, and insulation materials. This instrument applies a high-voltage power source, measures current, and calculates insulation resistance to ensure the safety and reliability of electrical systems.
Q： How do you test for insulation resistance?
A： Using an Insulation Resistance Tester:
1. Preparation:
– Disconnect the equipment or system from the power source.
– Ensure capacitors are discharged.
2. Set Up the Tester:
– Set the appropriate voltage range on the insulation resistance tester.
– Depending on system specifications, common test voltages include 500V DC, 1000V DC, or higher.
3. Connect the Tester:
– Connect the positive lead (usually red) to the tested conductor or equipment.
– Connect the negative lead (usually black) to the grounding point or the equipment’s grounding point.
4. Perform the Test:
– Initiate the insulation resistance test using the tester’s controls.
– The tester will apply the selected voltage to the insulation, measure the resulting current, and calculate resistance using Ohm’s Law: R = V/I, where R is the insulation resistance, V is the applied voltage, and I is the measured current.
5. Record the Results:
– Record the measured insulation resistance value.
– Compare the result with the system’s recommended or specified minimum insulation resistance.
Q： What instrument is used for the insulation resistance test?
A： Insulation resistance testing uses an “Insulation Resistance Tester” or “Megohmmeter.”
Q： What is the standard for testing insulation resistance?
A： Insulation resistance should be around one megohm per 1000 volts of operating voltage, with a minimum of one megohm. For example, a 2400-volt motor should ideally have a minimum insulation resistance of 2.4 megohms. Plants may set their own standards based on equipment and operational needs for better performance and safety.
