Most of the devices associated with our day-to-day activities require a smooth and steady flow of electric supply. Diminishing voltage can cause great disappointment for us.
In simple terms, voltage fluctuation is a continuous change in the voltage when devices or appliances that require a higher load are extensively used. Extreme cases of voltage fluctuation can cause heavy damage to your life and property. It is important to investigate the root cause of the voltage fluctuation in your household or office.
It is an electrical device that is used to provide a stable voltage output to a load at its output terminals irrespective of any variations in the input i. The basic purpose of a voltage stabilizer is to protect the heavy goods, which consume heavy electricity for example air conditioning unit, refrigerator,TV etc.
There are three things that can happen when the power supply is insufficient- voltage fluctuations, power surges and spikes. The effects of this diminishing voltage include poor appliance performance, dim lighting and intermittent stopping of lights etc. Because of this, the appliances do not receive a proper amount of power they need, they become overheated and thus stop functioning properly.
A constant voltage can be obtained by balancing the magnetic forces acting on the movable coil which is achieved by positioning the movable coil perpendicular to the fixed coil. The voltage in the secondary coil can be increased or decreased by rotating the coil in one or the other direction from center position. A Servo control mechanism can be used to advance the movable coil position for increasing or decreasing the voltage; with this coil rotation, the AC voltage regulators can be used as automatic voltage stabilizers.
Electromechanical voltage regulators that are used for regulating the voltage on AC power distribution lines, also called as voltage stabilizers or tap-changers. To select an appropriate tap from multiple taps of an autotransformer , these voltage stabilizers utilize the servomechanism operation. If the output voltage is not in the range of intended value, then the servomechanism is used for switching the tap. Thus, by changing the turns ratio of the transformer, the secondary voltage can be changed to obtain the acceptable values of the output voltage.
The hunting, which can be defined as the failure of the controller to constantly adjust the voltage; it can be observed in the dead band wherein the controller do not operate. It is a type of saturating transformer which is used as a voltage stabilizer; it is also called as ferroresonant transformer or ferroresonant regulator. These voltage stabilizers use a tank circuit composed of a capacitor for generating nearly constant average output voltage with varying input current and a high-voltage resonant winding.
By the magnetic saturation, the section around secondary is used for regulating the voltage. A simple, rugged method is used for stabilizing an AC power supply which can be provided by saturating transformers. Due to lack of active components, ferroresonant approach is an attractive method that relies on square-loop saturation characteristics of the tank circuit for absorbing changes in the input voltage.
Series or Shunt regulators are frequently used for regulating the voltage of the DC power supplies. A reference voltage is applied using a shunt regulator like Zener diode or Voltage regulator tube. These voltage stabilizing devices start conduction at a specified voltage and they will conduct maximum current to hold the specified terminal voltage.
Excess current is diverted to ground often using a low-value resistor for dissipating the energy. The shunt regulator output is used only for providing the standard reference voltage to the electronic device called as voltage stabilizer, which is capable of delivering much larger currents based on the demand.
These voltage stabilizers are used on generator sets, emergency power supply, oil rigs, and so on. It is an electronic power device used for providing variable voltage and, this can be done without changing the power factor or phase shift. Or Sign In With. Sign in with Facebook.
