How To Solve The Problem Of Unstable Voltage?

Voltage instability mainly manifests itself in two aspects. One is voltage deviation, and the other is voltage fluctuation.

1. Voltage deviation is when the voltage is too high or too low in a certain period of time, and the actual voltage deviates from the rated voltage, while the deviation is relatively stable. The magnitude of voltage deviation mainly depends on the system line impedance and the changes in active and reactive loads. Voltage deviation mainly depends on the line usage location and usage time. Most line ends have low voltage during peak hours, while the voltage is high in the second half of the night.

The main measures to solve voltage deviation are: apply to the power supply bureau to increase the total transformer capacity, transform the line to increase the cross-sectional area of ​​the line, connect multiple groups of lines from the transformer end, and reduce line impedance; improve power factor, and personally use voltage regulation. You can choose power products such as voltage stabilizers. Automatically compensate voltage to stabilize voltage output.

2. Voltage fluctuation is when the voltage fluctuates greatly in a short period of time, the actual voltage amplitude changes "dramatically", and the voltage fluctuates. Voltage fluctuations are mainly caused by impact loads caused by rapid changes in the load of large electrical equipment. The start and stop and loading and unloading of large motors, such as steel rolling mill biting, crane lifting and starting, arc welding machine arcing, electric locomotive starting or climbing, etc., all have impact loads. The magnitude of voltage fluctuations is mainly determined by the frequency of voltage fluctuations, the magnitude of fluctuations, and the quality of workplace lines.

The main measures to solve voltage fluctuations are: increase the capacity of the power supply system, replace large-capacity transformers, pull dedicated power supply tasks from power stations, and apply to increase the power supply voltage level; use dedicated transformers and dedicated power supply lines in industrial and living areas; improve production equipment and equipment startup time intervals. Individuals use voltage stabilization methods, you can choose power supply products such as Static Voltage Stabilizer. Automatically compensate for voltage to stabilize the output voltage.
