3) Electrical motor stater
Aim :- to know about the electrical motor starter .
Requirement :- plier , screwdriver, all type of spanners ,hammer ,tester, wire cutter , electrical
Knife .
Procedure :- first we took a starter and we started to find the faults in the starter. And took  the information about the starter then we took the information about the parts of the starter then we took the information about each part and it’s working process .
Relay :-  it is use to set the overload  connection current .it contain two strips  of bio metals.
Biometals strip :- when current is more the circuit breaks .the one  strip of lower temperature  gets Bend  due to heat.
Plangers :- it is use to bring the  supply back to the current.
Non volt coil :– it gets a magnetic field . and energy is created
Trouble shoot :- in starter ,
In case if supply given to the started  while testing on a lamp if the lamp glows then the coil not  working .and if the supply given to the started and lamp glows dim then coil is working ok.
We can also check by the magnetic field created by the coil.it the coil does not produce
Magnet then it is faulty and if it  produces magnetic field then it is working properly .
