Is It Useful To Use A Voltage Stabilizer When The Three-Phase Voltage Is Too Low?

(MENAFN- GetNews) How to solve the problem of insufficient three-phase voltage? Voltage instability can be solved with a voltage stabilizer. The answer is yes. The voltage stabilizer can solve the problem of low voltage. However, when purchasing a voltage stabilizer, it is necessary to test the voltage fluctuation value in the local area. When purchasing a voltage stabilizer, the voltage stabilization range of the voltage stabilizer must be greater than the voltage fluctuation value in the local area. What is the impact of low voltage on equipment? First, low voltage will reduce the capacity of power transmission and transformation equipment, reduce the charging power of transmission lines, cause large-scale power outages, shorten the service life of equipment, and even burn electrical appliances. When the voltage is too low (below 5%), the motor becomes shorter and the voltage square relationship decreases, which makes the starting torque drop a lot and the motor difficult to start (slow start or even no start); Second, if the load of the running motor is constant (under heavy load or rated load), the rotor should maintain the necessary electromagnetic shortening to balance the resistance torque of the load. This forces the rotor current to increase, resulting in an increase in stator current, causing the motor to overheat, increase temperature rise, shorten the motor life, and even burn the motor. There are many cases where the motor starts running at low voltage, and the load should be reduced as much as possible or used intermittently. The motor voltage is generally allowed to fluctuate within the range of 10%~-5%. If the power supply voltage is 380 volts, the motor is allowed to run for a long time between 418 and 36 volts.

Solution to low equipment voltage

1. In addition to thickening the incoming line, it is also necessary to check whether the power factor of the electrical equipment is relatively low, resulting in an increase in line voltage drop. If it is the power factor, reactive compensation is fine. 2. Some equipment can also be transformed for energy saving and the motor can be replaced efficiently. Energy-saving equipment consumes less power and can solve the problem of low voltage. 3. Install a three-phase fully automatic compensation power regulator, which is an automatic auto-coupling adjustable transformer. This device can stabilize insufficient voltage. Increase higher power compensation. Is it useful to use a voltage stabilizer when the three-phase voltage is too low?

One of the functions of the voltage stabilizer is to control the output voltage of electrical appliances with large current fluctuations within a certain range, thereby ensuring the smoothness of the circuit and the normal use of the electrical appliances. Voltage instability can be solved with a voltage stabilizer, the answer is yes! If the three-phase voltage is too low and exceeds the voltage regulation range of the voltage stabilizer, please use a terminal booster, which is better than a voltage stabilizer. When the three-phase voltage is too low, the voltage stabilizer will trip for self-protection and there will be no output voltage.
