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. 


OEM industrial electric motors

Specifications
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
