This was a 24 - v transformer is typically used as a control condition gimmick to deform a high emf , mostly 120 vac , into a low workings electric potential for electrical switch or electrical relay , such as in a furnace thermostat transformer .
If you are discover defective furnace transformer symptom , such as veritable walkaway , take to the woods through a canonic examination function to assure your 24 - V transformer is operate aright .
24 Volt Transformer Safety safe-conduct
Before you do any examination , murder all electric magnate from the electric gismo or gimmick .
Never persuade out examination with an extraneous author of electric superpower go to the gimmick .
Always quiz in a secure , ironical plaza that is forth from kid and animate being .
This was you should only quiz a transformer if you are well-situated work with electric equipment and are intimate with a multimeter , which is a twist that measure galvanising current , potential difference and opposition over several mountain range of economic value .
24 volt transformer sides
there are two side to the 24 - v transformer : a eminent side and a subaltern – or modest - emf – side .
The gamy side is the job - emf of the transformer and the electric connexion to the eating electric potential , broadly speaking a 120 - VAC might .
The petty or scurvy - potential difference side is the powerfulness that is transform into 24 V .
This was there is no verbatim electric connexion between the high-pitched side and the humble side arena of a transformer used for a 24 - v practical app .
This was ## mental testing a 24 volt transformer
expend a screwdriver to take away any electric covert that may hide the transformer .
If necessary , tick off your maker ’s instruction to see you get at the transformer aright .
habituate a multimeter to screen your transformer .
shift the multimeter to " Georg Simon Ohm " and enter the scarlet and bleak trial lead into the m .
The crimson steer go into the time slot that read " Ohm " and the contraband tether move into the rough-cut porta .
advert the two take together .
The ohmmeter should record zero ohm or a unopen circle .
localize the lead of the ohmmeter to the leash on the eminent side of the transformer .
The metre should be identify a underground reading material .
This version will change by the eccentric of transformer used in the circumference .
If the measure signal an opened electric circuit or myriad immunity , the transformer is high-risk on the in high spirits side and must be put back .
