Automatic voltage controller, Our Integral Transformer with HT-AVR is a distribution transformer upto 3000 KVA capacity with an integral servo voltage regulator connected on the HT side of the transformer. Its superior features not only help you to conserve energy but also avoid detrImental effects of over voltage, under voltage and unbalanced voltage on your costly electrical equipment & finished products. Constructionally, it consists of two interconnected tanks, one housing the distribution and buck-boost transformers and the other housing the servo voltage controller as shown in the single line diagram. In case there is a voltage fluctuation on the HT side the controller will move the carbon brushes on the dimmer unit to tap the equivalent of voltage to be added or subtracted on the HT side. This voltage would then be fed to the buck-boost transformer connected to the HT input of the distribution transformer. The buck-boost transformer will, in turn, add or subtract it from incoming HT voltage, so that HT voltage is always maintained at its set value. A bypass handle is provided to ensure that the voltage control unit can be bypassed, in case needed.

We strive to offer complete power solutions to our clients. For fulfilling our clients needs we deliver them the best quality products. Servo Voltage Stabilizers is a 3-phase, distortion-free, automatic voltage controller that gives perfectly stable output even under severe conditions of unbalanced voltage. It increases life of your equipment, reduced heating and minimal losses. Voltage fluctuations & phase unbalance cause several problems in industrial, commercial & residential sectors, such as:

• Reduction in motor efficiency, overheating and fast ageing of motors and switchgears
• Stoppage of production, inconsistent product quality and increase in wastage
• Malfunctioning & data loss in electronic/ CNC equipments
• Quick burn out of light fittings, bulbs & lamps
• Higher consumption by lighting load
• Higher demand & higher energy bill
• Loss of competitive position
• Capacity for servo voltage stabilizers -10 KVA TO 5000 KVA

ENERGY ENHANCEMENT BY USING POWERWARE SERVO VOLTAGE REGULATORS:

You can now enhance the quality of power, as well as save power, by using Powerware servo voltage regulator. It is a distortion less, servo controlled stabilizer available up to 3500 KVA capacity. It works on the principle of sine-wave superimposition. It bucks or boosts the incoming voltage by superimposing a variable voltage having the same waveform.

Powerware servo voltage regulator is the proven solution to all above problems caused by voltage fluctuations & unbalance. It saves your costly equipments & processes from detrimental effects of fluctuating & unbalanced voltage & gives you mental peace to concentrate on more important business issues.

Above all, Powerware servo voltage regulator can substantially add to your bottom-line by saving up to 20% power, depending on the incoming power quality.Powerware Stabilizers are available with wide input voltage range in both Air Cooled and Oil Cooled models upto 3500 KVA.

A bypass handle is provided to ensure that the voltage control unit can be bypassed, in case needed.The entire unit is designed as an outdoor, oil cooled unit with a simple bypass system. This will ensure that the transformer continues to work uninterruptedly in the unlikely event of a breakdown in the voltage regulator unit.

Power ware compact substation (CSS/PSS) consists of in house built metal enclosure, MV switchgear, transformer, LT switchgear, power factor correction system and other site specific requirement. Powerware compact substation is a tailor made product which can be also designed as per customer limitation and requirements.

CSS will occupy only th of the space in comparison of open conventional installation. It can be installed anywhere in basement or on the rooftop. Compact substation solves many considerations of architects like aesthetics, safety, space requirements & easy and quick installation. Our CSS are also available with our 4HD model transformer so that our CSS will be more reliable, and helps us and as well as nation to save energy.
