Many times in the choice of Step Up Transformer needs to be regulated when there is no grasp of the relevant application of occasions, to cause unnecessary trouble later, failed to achieve the effect of the use or settlement. That the regulator is the name suggests is used to stabilize voltage, measured otherwise, any of the equipment only in specified circumstances to be able to develop the desired results.
* Long distance transmission cable voltage drop caused by:
Not in the transmission and distribution lines with load (equipment) is generally the case detection voltage 380 V nominal voltage grid (electricity here that is industrial and mining enterprises) or slightly higher than nominal voltage, until the time when the work equipment (also is often said that the load / unload), the measured voltage drops to 330 volts nominal or less than the measured voltage. Within seconds, the voltage is fluctuating more than 30 volts peak.
* The nominal cross-sectional area cable serious enough:
Cable carrying capacity is required, you can refer to the national carrier to allow the power cable standards.
Generally more than 70 square twisted-core cable per square unit 3 - 5 current, 70 to 150 square square is 2 - 3.5 current is appropriate. (For reference, the actual laying of the cable to the maximum load and the actual distance to determine the transmission and distribution)
* High on the same cable boot device:
Transformer from the power transmission and distribution lines to the user terminal to which the above single or a few high-power start-up equipment, in front of the device did not add any soft-start device, it will make the same cable with other devices 1,2 S short can not work within or are forced to shut down, give the operator a lot of trouble to bring fatal harm other equipment. If the use of the computer shutdown, restart, and so on mechanical equipment, especially digital electronic devices, such as a direct result of burning of the master chip, and its harmful consequences can be imagined.

Mentioned above these types of situations can not be directly selected the conventional market s Transformer company to regulator, for the above situation must be after the manufacturer s instructions, sent to the scene by the manufacturer after the development of special programs to solve the voltage problem is not normal.
