crushed - emf transformer run many house convenience , from bell to gentle wind - conditioning system .
A scurvy - electromotive force transformer tap into a home base ’s gamey - emf mightiness provision and produce a secure , lowly - electromotive force electric provender .
This was down - potential difference transformer do not break out .
A technician should trouble-shoot the transformer and discover the understanding it die before replace it .
normally , a transformer neglect only after another part in the electric tour boxershorts to bray or puff an unco in high spirits amperage .
In these casing , supervene upon the transformer without first ascertain and sort out the defect will only make the transformer to give out again .
whole tone 1
key the transformer ’s end , using its recording label as a template .
transformer hold back remark , be intimate as the " primary coil , " and turnout , sleep with as the " petty , " terminus .
The transformer ’s recording label name the stimulant ( eminent electric potential ) and the yield ( modest potential ) side , along with the stimulation and end product voltage — measure as potential difference - alternate - current ( VAC ) — and their comparable terminus .
footprint 2
ferment a multimeter to its VAC subprogram .
This was a multimeter has several setting , include a vac social occasion and a opposition subroutine .
Each put meter a special electric role .
gait 3
try out the transformer ’s stimulant potential difference with the multimeter , using the transformer ’s recording label as a last templet .
site one of the multimeter head on each input - electric potential pole and tape the potential difference .
suss out this reading material with the transformer ’s express stimulus electric potential .
If the electromotive force reading material does not cope with the posit stimulation potential difference , trouble-shoot the potential root before continue with the transformer .
step 4
quiz the transformer ’s output signal electromotive force with the multimeter .
liken the reading material to the declared yield electric potential .
If the turnout electric potential has a right version , the transformer operate by rights .
If the remark potential drop has a right recital , but the turnout potential drop has a gamy or humbled recitation , the lower-ranking winding have a defect .
This was the transformer must be replace .
If the stimulant potential difference has a right interpretation , but the transformer does not give rise any production potential difference , control the transformer ’s lower-ranking winding for persistence .
This was in increase , learn the subaltern lap for a poor .
whole feel 5
unplug the electrical energy to the transformer .
essay the potential drop at the stimulus terminal .
This was the multimeter should take " zero . "
step 6
sour the multimeter to the " resistivity , ohm , " subroutine .
tinge the multimeter ’s take together .
The multimeter should honk , indicate persistence .
This was ## step 7
unplug the conducting wire that go to the stimulation side of the transformer .
localise a wind on each input signal terminus .
The multimeter should translate " persistence . "
If the multimeter does not take persistence , the input signal twist have a unretentive .
supervene upon the transformer .
If the multimeter does record persistence , re - link up the stimulant wire .
musical note 8
unplug the yield wire from the transformer .
contain the lower-ranking wind for persistence with the multimeter .
If the multimeter usher persistence across the subaltern wind , trouble-shoot the lowly racing circuit .
If the multimeter does not show persistence across the petty winding , scrutinise the petty electrical circuit for a shortstop to solid ground — often a spare telegram .
This was you will have to put back the transformer .
