Guide to Voltage Fluctuations and why they happen in your Home?

servo stabilizerBefore beginning to explore the world of electricity and voltage fluctuations, it is essential to understand the basics of voltage. Voltage is the basic building block of electricity that can help you understand the manipulation and utilization of electricity. Voltage is the driving force of current; it is the electromotive force that pushes free electrons from one atom to another in the same direction. In general, Voltage is the pressure from the power source of an electrical circuit that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a bulb or fan.

What are Voltage Fluctuations?

Servo Star, the servo voltage stabilizer manufacturer in India explain the term voltage fluctuation, they suggest that amplitude modulations of the fundamental frequency can be referred to as Voltage fluctuations. The below mentioned equation will help you understand better:

Voltage(v), at a given time(t):


Where V represents the RMS voltage, f0 is fundamental frequency, and m (t) refers to modulation. By choosing an appropriate expression for m (t), you can use the previous equation to describe basically any type of voltage fluctuation. For example, if we talk about a sinusoidal voltage fluctuation, you can express the modulation, m(t), by using the given equation:


Where M stands for modulation amplitude, fM is the modulation frequency, and φM refers to initial phase of the modulation.

Well if you are a reader who didn’t understand the scientific explanation, don’t you worry Servo Star a leading servo stabilizer supplier in India who have the right kind of explanation for you:

Voltage Fluctuation is something we have experienced in our homes. The voltage fluctuations can cause lights to flicker, turn off and then on again or glow brighter. Display screen of the computers may flicker as well.  On some occasions when voltage is very low electronic equipment, such as a computer, may fail to start up. So what exactly is voltage fluctuation?

Voltage fluctuation can be seen as a regular change in voltage that happens when devices or equipment requiring a higher load are used. The effects of a voltage fluctuation are similar to the effects of an Undervoltage (when voltage drops below intended level). The challenging part of voltage fluctuations is it can lead to computer systems losing its data, while televisions or radios may experience interference. This power problem may have a consequential effect on the lifespan of incandescent bulbs, since they are designed to be used for a specific voltage.

According to Servo stabilizer manufacturer in India, Servo Star, the effects of these voltage fluctuations can cause some serious problems. Voltages can drop upto 20% of nominal, which can result in exorbitant damage and time consuming errors, loss of important information, recovery and rerun costs and possible equipment damage.

Why Voltage Fluctuations happen in your home?

Already facing the brunt of frequent power cuts, the last thing an individual needs in their house is voltage fluctuations damaging the house appliances equipments like air conditioner, refrigerator or microwave ovens. These effects may be very disturbing and control this situation in your home Servo Stabilizer Suppliers in India share with us the possible causes why voltage fluctuations happen in your home:

  • Wiring Effects

Poorly designed wiring leaves a house with lesser electricity than needed, or it leads to ungrounded wire outlets to leak electricity and cause tough-to-solve power fluctuation issues. Wiring can also get damaged or disconnected by insects and/ or other animals that nest inside the walls. Issues with the house’s wiring create fluctuations when there is increase in energy drawn. A qualified electrician uses certain equipments to identify the problem source and repair the wiring without touching all of the home’s walls. Loose connections in your house wiring and from the circuit breakers to power outlets can also cause voltage fluctuation issues. Another problem can be the use of undersized wires in your house wirings.

  • Flickering

Flickering can occur because of the variations of input voltage sufficient in duration to allow the visual observation of a change in the intensity of electric equipment source. 

  • Notch Filter

Not using a notch filter can be problematic as it is used to remove a particular frequency, having a notch where signals are rejected is very useful. 

  • Overloading

 If where you live, the houses draw more load current than allowed by the authority, then it can lead to low voltage in your area.

  • Frequent use of heavy inductive loads

Another reason could be the use of heavy inductive loads more often, at the same time, such as the air conditioner, refrigerator or motors together. If  heavy loads are used simultaneously, then there can be voltage dip.

  • Natural causes

Striking of Lightning, birds or squirrels on power lines and falling trees all lead to power fluctuations that are difficult to avoid. Where lightning and fallen trees mostly lead to a complete power burnout, the animals or debris hanging on the wires leads to surges in electricity. Surges and swells in electric current often effect computers and other electronics, but Servo Stabilizer Manufacturers in India state, a simple stabilizer deals with the extra electricity before it reaches those devices.
