What is the solution for a regulated power supply?
There are three reasons for the problem of supply voltage.
1) power plant generator regulator device problems, resulting in fluctuations in output voltage. Such are generally small hydropower stations.
2) substation or distribution station power transformer performance problems, especially in disrepair aging serious.
3) The total electricity consumption in the area is much higher than the power supply load, resulting in the supply voltage is low, serious and even the frequency of power supply will be low so that the power grid paralyzed a large area power outage!
AC power supply voltage fluctuations in the main situation of the following two points:
(1), the voltage fluctuated, can not be stabilized within the scope of the standard voltage permit;
(2), the voltage continues to be high or low. The above two cases for the safety of electricity and electrical safety are a lot of unfavorable factors. With long-term work in such a voltage environment will cause air consumption increases, increased current consumption, reactive power is high, a serious rise in temperature, electrical appliances can not work properly and so on. More serious will burn the electrical, and even cause a fire!
In the input side of the regulator.
At present, due to power supply facilities and regional conditions and other factors, China's AC power supply voltage fluctuations are still relatively large. Especially in some remote, rural areas.
