First you desire the voltage and resistence as per you using.
phase to pase testing should be reading shows 1 its ok or its shows resistence its not ok.
earth to phase its shows 1 ok.supose it shows some resistence its not ok.
Neutral to earth its shows zero ok,supose its shows a resistence it is not ok.
What else can I help you with?
How insulation test is prform on megger?
A megger test is used to look at the insulation properties of motor windings, electric wiring, high power antenna mounts, and other similar items. The voltages are a lot higher than they are with a normal Volt-ohm meter. You will turn the device off and connect it to a source of power. The circuit breaker being testing should be closed and then disconnect the line-side circuit. Connect the output terminals and turn on the test set. Get the desired current and make any necessary adjustments. Then, you will hit the 'start' button and get your readings.
Can you megger or test an rcd?
yes
What is the g in a megger test?
It is the terminal on the megger that the ground cable connect to when testing a device to ground.
How megger produce voltage?
The megger is used to find insulation resistance in any equipement. It will generate around 10kVA power to test.
What is the minimum resistance between phasea in megger test?
infinity
Conduct electrical megger test. what would be the minimum readings you would expect?
Infinity
What is the number of a megger test to shoot for?
A good number on a megger test should be around 2 megohms.
How accurate are the readings of a megger test?
While using megger we only have to see whether resistance breaksdown at the upper value mentioned. Since megger generates high voltage we can check whether breakdown takes place or not.Megger has a range from o to infinity.So it is not possible to find accurate resistance,hence it is used as an insulation tester

What is the importance of Megger test?
Megger tests are important because the test makes sure that your electrical insulation is safe and operating as intended. Megger tests are performed using a Meg-ohmmeter.
Can you megger or test an rcd?
yes

What is the minimum resistance between phasea in megger test?
infinity
What type of voltage applied during megger test?
DC
What happens if a megger test fails?
If a megger test fails you have a short between the two wires or the wire to ground that you are testing. This short circuit has to be repaired before the equipment is placed back into service.
How much time duration is required while Meggar test is applied?
The time duration for a megger test is as long as it takes to turn the handle of the megger about five times. Voltage is generated on the first turn and if there is an insulation breakdown on the device being tested it will show instantaneously. If the megger is an electronic megger hold the generate button down for about three seconds.
