Why the Power Quality is very important?

For electrical systems to function properly, it is necessary to make sure that the Quality of the power feeding is a sufficient quality to ensure that performance Is not affected or system life expansion is reduced. Without the proper power, an Electrical device or load may malfunction, fail prematurely or will not operate. There are many ways in which electric power can be of poor quality and many Incidents take place.

Do you actually know the mains supply problems ?

To identify proper solution it is always recommended to identify the problems you are facing. You may of course already have a good idea as why the problems occur. If not, it will be necessary to monitor the supply over a period of time to
Identify the types, duration and Magnitude of power problems happen. Power Supply problems are caused by various sources, for ex., distribution network Faults, system switching, Weather and environmental conditions, heavy plant and
Equipment or simply faulty hardware.

How do you decide the size of the equipment you reqd?

When you are deciding the total power rating required for the load ratings it is always recommended to allow for possible future expansion of the load you are planning to add or protect your future equipments. You will have to check the rating of the equipment to be protected. Those ratings are normally available in amps or kVA, single or three phase on the equipments. You will also need to decide the nominal voltage line to neutral and line to line if three phase, Frequency and power factor. Otherwise you will need to consult the manufacturers of the equipment or take your electrician on consultant advice. It is always recommended to measure the loads true RMS value.

What is the best solution for your problems?

If you have a good idea as why the mains problems occur, then you can identify clearly the best and most cost efficient solution. Online UPS (Uninterruptible Power Supply) will often be viewed as the obvious choice. But pl be noted, that these are expensive to buy and high maintenance cost. most of the applications where the loss of mains is not really a critical issue, or can be compensated by use of a diesel generator, providing an Automatic Voltage Stabilizer / Regulator will be a more cost efficient .and these solution both in terms of initial outlay, maintenance, support costs and they required local skill to install, maintain and support are always less and give long life.

What is the difference between a Voltage Stabilizer and Power Conditioner?

One of the most common questions we get asked is what exactly is the difference between a Voltage Stabilizer and an AC Power Conditioner. These both are protecting against voltage transients, spikes, sags and brownouts, but an AC Power Conditioner also offers additional protection against Electrical Noise and higher level defense against transients and spikes. In most cases an AC Power Conditioner is simply a Voltage Stabilizer with the inclusion of an isolation transformer. When a good earth cannot be provided ‘Common Mode’ Noise (E to L and E to N) can be a problem. With the inclusion of a shielded isolating transformer in a Power Conditioner, this interference will be suppressed to harmless levels. The output of an AC Power Conditioner is commonly referred to as a ‘Clean’ supply. as you would expect an AC Power Conditioner is normally more expensive than voltage Stabilizer / Regulator.

Why is determining the input voltage variation you are experiencing and output voltage accuracy required important?

Choosing a stabilizer with right input variation capability is important because if its input voltage range is exceeded, then its output will increase or decrease by the same amount by which it has gone "out of limit". In situations where there is a good mains supply, a stabilizer offering an input variation swing of ±15% will usually be more than acceptable, but in more remote locations, where supply infrastructure is less of ±20% or greater may be needed to be accommodated by the stabilizer. As a general rule the greater the input voltage swings the stabilizer / conditioner needs to correct the greater the price. An output voltage to within ± 1% / ±1.5% of the preset output voltage is the norm when specifying a Voltage Stabilizer or Power Conditioner. However if a lower output voltage accuracy can be accommodated by the load equipment, then the input voltage range Can be extended proportionally. As the cost of the stabilizer is linked to the input voltage range it has to handle, accepting lower output accuracy may prove to be a more economical solution.

Is Supply Frequency Important?

With most supplies operating on 50 or 60 Hz, your normal mains supply frequency is unlikely to vary more than +/- 2%, and this is well within the capability of most stabilizers and conditioners. But if the supply is from a local generator it is possible that the frequency could deviate beyond this range and suitable protection should be considered to protect both the load and the power protection system.

Are there any other factors you should consider when choosing a Voltage Stabilizer?

Bypass Facility: You may also consider to fitting a bypass switch that will facilitate the inspection and maintenance by isolating the stabilizer and connecting your Load directly to the mains supply. Low & high voltage cutoff is reqd when the power supply goes beyond the limit of the design Overload protection cutoff is required when the initial load is applied beyond the permitted/designed for the purpose.

Advantages for Centralized Automatic Servo controlled Voltage Stabilizer

When we fix a Centralized Automatic Servo controlled Voltage Stabilizer No need to fix individual stabilizers for the products like TV, Refrigerator, Air Conditioners etc.

If, Centralized Automatic Servo controlled Voltage Stabilizer is fixed at Home, Bunglows, Apartments, Villas, Hotels & Resorts ,Sound Engineering Systems including Factories, Clinics & Hospitals etc ,the Total Load like Tubes, TV, Fridge, AC, Micro Oven, Mixey, Grinder, Iron Box, Washing Machine, Dish Washer, Electric Stoves and Burners, LCT TV and Monitors, Computers, Music system, Decorative Lights, Heaters all these loads will be protected against Low and High Voltage Problems. Thus an Client can save lot of money and of course the valuables and Time.

The Centralized Automatic Servo controlled Voltage Stabilizer is Available in Single & Three Phase with Air & Oil Cooled varieties depends upon the requirement and application as per the need of the client.

Also the Centralized Automatic Servo controlled Voltage Stabilizer is categorized in different Voltage levels as per the demand and requirement like Normal Range and WideRange depends upon the place and the voltage available at that particular place and desire of the client.

When the client wants to fix a Centralized Automatic Servo controlled Voltage Stabilizer, it is strongly recommended to fix it after the meter of govt supply.
