The use of voltage transformer should be paid attention to the following matters

 electric motor stator rotor lamination motor parts 
Specifications
1. Lamination of electric motor 
2. IP54 class F 
3. 100% copper 
4. silicon steel stamping 
5.stunning performance 
1) the secondary side of voltage transformer at work can not be short circuit. In normal work, the second primary side current is very ac electric motor small, almost open state, when the secondary side short circuit, the current large impedance is small (secondary side) will be burning equipment. 2) the secondary side of voltage transformer must be grounded at one end, to prevent the primary and secondary side stroke wear, high pressure into the secondary side, endangers one's personal and equipment safety. 3) voltage transformer connection, one should be paid attention to, the polarity of the secondary side terminals.

1. effiency: IE2 and IE1 
2. 20 years manufacturing experience 
3. 12 months guarantee 

4. low noise and vibtration
So as to ensure the accuracy of measurement. 4) the primary and secondary side of voltage transformer are usually should be installed fuse as short circuit protection, primary side should be ANP gost motor installed at the same time isolating switch for safety maintenance. 5) in a circuit and a side PT ark: popular, high screen top small bus voltage of the power supply is provided by the PT ark, PT incase there are both measured PT and PT measurement motor electric (the original is that requires the separation of PT and PT measurement is measurement, the rules and regulations of because measuring the level of transformer is higher than the level of protection of transformer, but now such as no special requirements are not separated, sharing), all small busbar voltage on the top of the screen, for other qualification high voltage measurement, metering, protection with power supply, etc

No matter how many, than change of transformer is transmitter output generally acmotortrading.blogspot.com USES is 4 ~ 20 ma signal (far eastone purposes). Access, 100-5 transformer transducer output 20 ma corresponds to the actual current 100 a, 3 phase ac induction motor 4 ma corresponding to 0 a; Access, 300-5 transformer transducer output 20 ma corresponds to the actual current 300 a, 4 ma corresponding to 0 a. ABB inverter ACS800 parameters With resistance in Single phase motor circuit, the current is used to perform a task, to pass on information. If too small, the information will be a loss; (a little rent, a current is too small, to 3 phase induction motor the receiver, the current is too small, so that the receiver can't analysis and accept it.) But is too big, will blow out circuit (not seen collection circuit, so thin copper wire, or painted, current is too large, many with no?)
