Cost of small capacity transformer single-phase power supply system construction, light load area can reduce construction investment. Big load region of single-phase power supply acmotor2.blogspot.com system renovation, must have a larger economic investment. I see, some pilot single-phase transformer in residential quarters, is a large transformer into multiple small transformer, near load installation, shorten the distance, a low pressure trunk, due to the distance of the source to auto parts the load is certain, shortening the distance between motor parts low voltage power supply, is bound to extend the transmission distance, this transformation requires a lot of investment, such as electric motor 12v 500w the original 3 unit 30 families use 160 kVA three-phase transformer.

switch to three single-phase 50 kVA transformer power supply, table 2 lists two retrofit scheme of materials and the change of loss, obviously increased the construction investment. First, in order to reduce the low voltage main line loss, to introduce the high voltage line load center, increase the high voltage line construction investment. Secondly, using many sets of small capacity transformer no-load loss and load loss, after all is more than the original list of large transformer. Third, the purchase funds are many sets of small capacity transformer is greater than the single purchase money of big capacity transformer. As residential electricity more abroad, several or each use of a single-phase transformer, because countries rich, large amounts of money into the electric power department. Although the investment is bigger, for their overall economical.

ZC25B - 4 test three-phase insulation insulation resistance meter

2. competitive price,high quality 
3. Accessories Series: stator and rotor
ZC25B - 4 type insulation resistance meter test three-phase insulation. The insulation ac electric motor resistance tests measuring leakage current between the two wires. So need to put the two clip sandwiched between two wire line core. (shaking table on the grounding wire don't let it empty) wire core yellow green, A and B are measured relative phase of the insulation resistance between A to B. Red line core green B and C, the Induction motor relative phase between measurement is B to C is insulation resistance. The wire core is A and C, the measurement of the insulation resistance is A relative phase between the C. Wire core A and N, insulation resistance measurement is A relatively is zero. A line core with PE, the insulation resistance measurement is A relatively. And so on. 1 kv under low pressure, the test ZC23 or 25, two clip clamp respectively clean two conductor, from slow to quick turn the crank, about 120 r/min, maintain uniform, pointer corresponding calibration is insulation resistance magnet generator value. Such as refers to 200, is 200 ohms.

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.
