Scope of application of turn-to-turn short circuit tester

Described earlier in the rotor winding interturn short circuit tester is applicable to all kinds of electric tools with ac motor rotor test,can also be stator applied to detection of dc motor rotor."Little experience" Unconditional homemade these tools such as readers,to find a 220 v electrical appliances with power transformer,such as power transformer for the black and white television.On the side of the core,with the hand hacksaw sawn into close to size.Can be determined according to the object of www.facebook.com/guohong.trading measurement,at ordinary times detection mouth (typically run backward trapezoidal) size.Here choose size is 52,mm (top),25 mm (below),then use electric Angle grinder or grinder precision grinding is good,must not hurt when sawing core transformer coil.This method of homemade interturn short circuit tester.When using check rotor winding,must first put the rotor,then can give interturn short circuit tester coil power supply.After the check,must first disconnect interturn short circuit tester coil perkins diesel generator set power supply,and then from the turn-to-turn short circuit test on the rotor.Otherwise,turn-to-turn short circuit tester will become open reactor,due to its winding excitation current is very big,will lead to coil burned interturn short circuit tester.Remember,the best in transformer winding circuit series specifications appropriate fuse.Once the operating error,fuse burn out,not burnt transformer winding.
