Due to the influence of various factors such as power supply facilities and regional conditions, the voltage fluctuation of the AC power supply grid in some countries is still relatively large. Specially in some remote and rural areas of countries with unstable urban networks.

The main conditions of AC power grid voltage fluctuation are as follows:

(1) The voltage fluctuates high and low, and cannot be stabilized within the range permitted by the standard voltage;

(2) The voltage continues to be high or low. The above two situations are very unfavorable factors for the safety of electricity and electrical appliances. The long-term operation of electrical appliances in such a voltage environment will cause increased empty consumption, increased current consumption, high reactive power, serious temperature rise, and electrical appliances cannot work normally. More serious will burn electrical appliances, and even cause a fire!

There are generally three reasons for power supply voltage problems;

1) There is a problem with the generator voltage regulator in the power plant, which causes the output voltage to fluctuate. Such are generally small hydropower plants.

2) There are problems with the performance of power transformers in substations or substations, especially those that are in serious disrepair and aging.

3) The total power consumption in the region greatly exceeds the power supply load, resulting in a continuous low power supply voltage, and even a low power supply frequency in severe cases, which will paralyze the power grid and cause large-scale power outages!

For the above-mentioned power supply grid with unstable supply voltage for a long time, it is impossible to change the status quo from the fundamental facilities in the short term. The best solution is to add an AC voltage stabilizer at the incoming end of the power grid.

1) For users with low power consumption and low requirements for household use , we have SVR series regulators for you to choose. The output of this series of regulators is (single-phase 220V± 2 %, 110V± 5 %).

2) For users with high power consumption and high requirements in large industrial places, power distribution rooms, substations, hydropower stations, national defense, railways, etc., we have high-power and high- precision TCR, TVR series medium and high-power three-phase voltage stabilizers device for your choice. The output voltage accuracy of this series of AC voltage regulators is (three- phase low-voltage version 220V±1~3%, three-phase 380±1~3%).
