How to Handle and Avoid Overvoltage Display in Three-Phase Voltage Stabilizers

Three-phase voltage stabilizers in China typically have a nominal voltage of 380V and are widely used in industrial equipment. Some users may encounter an overvoltage display while using these stabilizers. Different manufacturers have various methods for handling this issue, but generally, users can choose to disconnect the power supply and wait for the voltage to return to a stable range before restoring power.

1. Causes of Overvoltage Display in Three-Phase Voltage Stabilizers

To this end, all three-phase voltage stabilizers have a normal voltage value with maximum and minimum acceptable voltages that determine its voltage regulation range. When the voltage exceeds this set range, an overvoltage or undervoltage situation occurs.

2. How to Handle Overvoltage Display

An overvoltage display usually is an indication of insufficient chosen voltage regulation range by the chosen stabilizer. It normally comes from not making a correct determination of the maximum and minimum voltage values in the local area for unstable voltage conditions.

3. How to Avoid Overvoltage Display

One should first know, before the purchase of a three-phase voltage regulator, the minimum and maximum voltage values of the area to thereby give the range at which the voltage has been fluctuating. In the choosing of a stabilizer, one may opt for a regulation range that is higher than the actual voltage fluctuation just to make sure of safe operations of the equipment.
