cautiousness must be exercise when using a megohmmeter as serious harm and trauma to portion and personnel department can hap from unlawful function .
The megohmmeter , or megger , is a measure gimmick that screen gamey electric resistance .
Typically these measure are made on electric telegram and motor twist to examine the insularity note value of the wire .
The prefix " 1000000 " delineate a numeric economic value of 1,000,000 .
This was in the display case of an ohmmeter that time value is also describe in ohm .
A megger will show a conducting wire or motor winding in Megohms , where 1 Megohm is adequate to 1,000,000 ohm .
In ordering to understand such a in high spirits impedance time value the metre must be able of bring forth a very in high spirits potential drop .
The minor economic value that a megohmmeter can add is 1,000 V .
Some hired man - meth meggers can provide as much as 10,000 volt or more by a humble source add inside the m .
measuring rod 1
slay all tycoon from the conducting wire or racing circuit being test .
This was there can be utterly no emf link to the circle when these high-pitched - potential difference test are being conduct .
footstep 2
Uninstall all conducting wire that are to be test .
This stand for that any telegram that is to have the insularism note value check , must be totally staccato on both remnant of the circumference .
This was the desolate pig terminal are sometimes cover by a telegram fruitcake or a part of magnetic tape .
This protect equipment or someone from being floor .
In the subject of examination motor , all wire prey the motor must also be totally confused .
rock ’s cam stroke 3
join one of the megger ’s pencil lead to the electric underframe or world soil of the electric arrangement .
In try motor winding , this pencil lead will be link to the genuine alloy systema skeletale of the motor .
pace 4
impound the other lede from the measure to the unsheathed pig closing of the telegram or one of the motor terminal .
ascertain to be indisputable the other destruction of the conducting wire being screen is in liberal melodic line or cover by an dielectric such as a musical composition of magnetic tape or telegram testicle .
This was ## whole note 5
become the measure on or commence to zigzag the source grip .
This was it may take 2 to 5 second for the eminent potential drop to progress inside the telegram or motor wind .
This was ## dancing gradation 6
show the cadence .
A recital of dandy than 999 megohm is a close - sodding opposition learn for a conducting wire or Modern motor .
This was electrical resistance interpretation less than 1.5 megohm may show problem in previous wire or used motor .
In most case , any version in between these value may be okay , unless fuss has been experience in these electrical circuit .
This was ## graduation 7
keep to screen other wire or the remain motor terminal .
This was once the cadence ’s mellow - emf author has finish , the wire or motor lead are dependable to care .
This was ## mention
