Servo Stabilizer not only protects the electrical equipment but also is a good energy saver

Servo Stabilizers
Owing to the widespread electric fluctuations in India, all industries require stabilizers to stabilize the variation in current to prevent any damages to expensive equipments. Servo stabilizers are widely used in India as they come equipped with advanced electronically controlled servo motor concept that controls a motorized transformer.

Servo Stabilizer is mainly used in equipments that require high-energy consumption because it not only stabilizes voltage and protects the electrical equipment but also is a good energy saver.

Servo Stabilizer

1)Important factors to consider:
It is very crucial to understand various factors which affect the operation of electrical appliances and equipments as some of the major enemies for expensive electrical equipments is voltage fluctuation and phase unbalancing.Since every industry has its own requirements of power supply, it is important to understand your need before investing in this device. Servo Voltage Stabilizers are tailor made equipment and are usually customized as per actual voltage requirement of customer. For this, the actual voltage requirement and fluctuations must be analyzed before buying a Servo stabilizer.

2)Efficiency:
Stabilized electrical input to the machines helps to increase the efficiency of machines as well as improvement in the quality of the final product. High and low voltages cut off with overload protection are generally available in Servo Voltage Stabilizer but the best stabilizers must be equipped with features such as an inbuilt by pass system, surge & spike suppressor, single phase prevention and phase reversal, high/ low cut off, auto resumption and trip and alarm for abnormalities.

3)Energy and money saver:
Apart from the above, Servo stabilizers serve as a viable means to reduce bills too. The overall balancing of voltage loads also protects the equipment ensuring a long life for an industry dependent on electrical energy for its functioning.

In other words, servo stabilizers act as a shield to costly electrical equipments and by extension to the entire organization as they are used in industrial as well as domestic application.

blog, Electrical Voltage Fluctuation

Why would electrical voltage fluctuate in your home?

Lots of reasons are already explained, fluctuation in voltage out of which:- Flickering– due to variation of input voltage sufficient in duration to allow visual observation of a change in electric light source intensity.

Servo Stabilizer
Notch – A switching disturbance of normal power voltage waveform of duration less than 0.5 cycles, which is initially of opposite polarity than the waveform or may be due to simple under voltage condition. These may be caused due to:

  • Current and voltage distortion depending on the connected load that may vary widely in your house.
  • Harmonics:Generated by Rectifiers/Electronic Ballasts, SMPS  (Power Electronic Devices) etc.
  • Due to switching transients in sudden heavy loads like AC, Pumps etc.
  • or may be simply because of erroneous wiring/earthing or short-circuits.
  • Cause may also be due to other heavy loads (to your neighboring areas) connected to your secondary distribution transformer which brings power to your home.

It fluctuates in all houses. The power company tries to hold it +- 5% of a nominal value but it really can be +- 10 % easy. I have seen a nominal 120 VAC fluctuate from 100 to 145 volts. If the power company has lines and equipment that are loaded toward the maximum capacity, fluctuations will be greater than if they are lightly loaded.

Transmission supply from utility generator, varying load usage from devices, i.e. Tv’s, refrigerator-cycle based for desired temperature, washing machines, dryers, lighting, Chargers for various equipment like computers, phones and battery packs for tools. Also, loose contact points of outlets and circuit breakers – make sure connections are tight – 18 in/lb for outlets. Utility companies typically charge per Kilowatt on a tiered program depending on the peak demand of the day. Higher rates at peak hours 8am-4pm tier 1, 6pm-12am tier 2, 12am-8am tier 3. Each with a multiplier base depending on tier.

There can be many reasons to it.

  • The most common is overloading. If the area, where you live, draws more load current than specified by the authority, then there will be low voltage in your area. This due to the limited capacity of the distribution transformer used.
  • It can also be caused due to use of various electronic equipments like, reactor, inverters, etc due to the harmonics created by them.
  • Another reason can be due to use of heavy inductive loads frequently at the same time, like, ac, refrigerator, also motors. If you use heavy loads simultaneously, then there will be voltage dip.
  • Or else, it can be caused due to damaged wiring, or earthing system being faulty etc. They dissipate unnecessary power, thereby causing voltage drop.

Voltage fluctuation could be cause for the following reasons

  • If your house or your neighborhood draws excessive power, it will cause sudden drop in voltage level.
  • Lightning may cause power surges or spikes.
  • Clashing of lines. If power line are clashing because of strong wind, or trees, birds or some other accident may cause fluctuations.
  • Poor regulation by utility or variation in generation capacity may also cause fluctuation.

Gayatri Industry  is the reputed name for electricity fluctuation problem, They manufactured a machine called SERVO STABILIZER

Electrical Voltage Fluctuation

Why should we need stabilizer for our home appliances?

“Power supply is erratic at most places in India, with voltage fluctuating in both directions (up and down) at many places frequently. These voltage fluctuations can damage appliances, there by causing them to end much before their normal useful life. When voltage goes down, electric current in the appliance increase, which can result in burning of the appliance. Voltage Stabilizers have thus found place in many homes and offices in India. In this article we will talk about voltage stabilizers: what they do, how much power do they consume and how to select one for your setup.
What are Voltage Fluctuations and why do the happen in your home?
Voltage fluctuations are changes (increase or decrease) in voltage coming to your home that make the lights glow dimmer (for low voltage) or brighter (for high voltage) than normal depending. Typically they are not dangerous for most of the appliances, but then they do damage appliances with motors. But then they certainly vary the output of the appliance.
Reasons for Voltage Fluctuations in your home
Voltage Fluctuations typically happen because of bad wirings (to your house or inside the house), overload (be it you using more power than your sanctioned load or your neighbors using more), sudden switching on of high powered appliances (like air conditioners, motors), bad eating, or short circuits. Whenever you experience voltage fluctuations, do check for any of these reasons.
What are voltage stabilizers and how do they fix (avoid) voltage fluctuations?
As the name suggests, voltage stabilizers stabilize the voltage, which means if the supply voltage fluctuates or varies (is less or more than the acceptable range), it brings it to the desired range. It does so by using electromagnetic regulators that use tap changers with autotransformers. If the output voltage is not in range a mechanism switches the tap, to change the transformer to move the voltage in acceptable range. It does not give a constant voltage output, but operates the system in a safe voltage range.
How to choose a right sized stabilizer?
Sizing of a stabilizer is very similar to sizing of a UPS or Inverter (power backup). The most important thing is to know the load connected to the stabilizer. First you must note down the power (or watts) for all the appliances that will be connected to a stabilizer. The sum total of the power consumption (or watts) will give you the load on stabilizer in watts. But most stabilizer sizes are in VA (Volt Ampere) or kVA (kilo Volt Ampere which is equal to 1000 Volt Ampere). Although to get to actual VA (or Volt Ampere) from Watts (W) you will have to do some measurements, but to give a rough approximation, you can increase the Watts value by 20% to get the approximate VA size that you may need.
So for e.g. if sum of watts connected to your stabilizer is 1000 then you can take a 1200 VA or 1.2 kVA stabilizer. (Please note that 20% is suitable for residential systems and may not work in industries if your power factor is bad).
Important things to look for before buying a voltage stabilizer?
Before buying a voltage stabilizer the most important thing that you should make note of is the input voltage range that you get in your house. This is important because every stabilizer has a minimum and maximum input voltage to which it can stabilize the output voltage. If a voltage stabilizer has input voltage range of 150 V (min) – 260 V (max) then if the voltage in your house goes below 150 V or more than 260 V, then the stabilizer will just cut off the power supply to your appliance. But if it is 160 V or 250 V (within the working range), then it will try to stabilize it to the desired output voltage range.
