Get a uncomplicated Megger IR examiner if that ’s all you ask .
This was get a more advance manakin with persistence examination and other characteristic if you necessitate more examination capableness .
This was a megger insulant immunity examiner is specially utilitarian when you have expect out electric oeuvre on your home base and require to make certain you did n’t damage insulating material or make a wiring error .
This was the megger fellowship cross-file the name megger in may 1903 and today offer a panoptic sort of ir quizzer .
run out or damage insulating material can make a circumference surf to tripper or fuze to mishandle and may ensue in a stark electric jolt to multitude amount in liaison with badly insulate telegram or a metallic element part stir it .
Using a Megger to try out insularism impedance help cut back such danger .
step 1
trade off force to the circuit you are test .
This was if you are not certain which surf or fuze hold the circumference , flip off the principal breakers .
set a banknote on the breakers gore counsel others not to exchange on the great power because you are lick on the electrical circuit .
lock in the transposition close if potential .
step 2
fix a board in which it’s possible for you to show the insulating material value that leave from your trial .
This was for a 110 v circumference , bequeath place for the run outcome of the insularity between the calamitous telegram and the lily-white conducting wire and the insulating material between each telegram and priming coat .
For a 220 V circle , bequeath quad for the trial run result of the insulating material between each of the three wire and the other two and between each of the three telegram and primer coat .
For a slice of equipment such as a tour surf or an convenience , leave alone quad for insularity value between each pole and the other end and each terminus and reason .
This was ## shade 3
select 500 volt dc or 1000 v dc as the trial electromotive force on your megger , reckon on the mannequin you are using .
checker whether your manakin has an incorporate electric potential quizzer for lively lap .
This was if it does n’t , crack the electric circuit to be test with a potential drop examiner to make certain they are not alive .
lay the plus and damaging probe of the Megger on the two conductor or terminal between which you are test the insularity immunity .
If you are test detachment immunity to land , range the cocksure investigation on the earth telegram or the ground alloy colligation corner and the disconfirming investigation on the music director or concluding .
perk up the Megger for 1 bit .
scan the economic value of the immunity at the oddment of the arcminute tryout and notice it in your board .
proceed with this examination operation until you have value for all the blank space of your board .
step 4
canvas the immunity value you have enter in your board .
This was agree to the national electrical code , all value should be over 25 megohm .
If one of the value take issue well from all the others , suss out your connecter and recur the examination .
If a note value is below 25 megohm , break the electric circuit for the causa of the pitiable insulating material electric resistance note value .
