How do you use a Megger tester?
If you are testing insulation resistance to ground, place the positive probe on the ground wire or the grounded metal junction box and the negative probe on the conductor or terminal. Energize the Megger for 1 minute. Read the value of the resistance at the end of the minute test and note it in your table.
What does Con mean on a Megger tester?
a wrong connection to the
con usually means a wrong connection to the megger.
What does PE mean on a Megger?
The PE that comes up normally happens when one of the leads is not making contact. I doubt you have a P_E fault, this just seems to be code the tester gives out when one of the leads doesn’t make contact.
How do you read megger results?
If the megger reads a resistance under 1 (1,000 ohms) on your meter after the initial 60-second interval, the cable has failed and the cable should be removed. If the megger reads a resistance between 1-1.25 on your meter, then the cable passes. Any reading above 1.25 is considered excellent.
How do you PAT test a kettle?
Turn the switch on the kettle to the on position and plug the kettle into the tester. Ensure that your test lead is making good contact with the kettles element, as limescale deposits may result in contact issues, and result in a test failure.
What is touch voltage?
The term touch voltage refers to the shock hazard present on any exposed metalwork or protective conductor. The voltage exists if there is a higher resistance earth path to the exposed metalwork than to the ground beneath your feet or another piece of exposed metalwork in close proximity, as shown in figures 1a & 1b.
What does Megging a wire mean?
A megger is also known simply as an insulation tester. It’s basically an ohmmeter, but it’s one that generates its own electricity under high DC voltages, such as 500 and 1,000 volts, and transmits it in small currents through the cable to be tested. The voltages are high, but the currents are small enough to be safe.
What is the insulation resistance?
Definition of insulation resistance : the alternating-current resistance between two electrical conductors or two systems of conductors separated by an insulating material.
