SERVO CONTROLLED VOLTAGE STABILIZER (SCVS) Both electrical and electronics appliances occupy a prime place of importance in our lifestyle and thus usage of electricity in modern life has substantially increased. But, voltage supply, on the hand, receives very little attention from the consumers. Surprisingly, unstable voltage supply has the potential of causing havoc due to lack of foresight on our part. Even you must have observed the heavy variations in voltage supply during day or night, which results in frequent breakdown, Low production and loss of energy. Thus you need to consider good quality servo controlled voltage stabilizers with various important factors taken into account. This will not only ensure safety but an effective reduction in electricity bills and an increased life span for your sophisticated equipment's. We, Arzoo, are manufacturing servo controlled voltage stabilizers ranging from 1 KVA-1500KVA [conforming to IS:9815] available in multiple configurations, that undergoes through a series of quality tests conducted in our laboratory.

A voltage regulator is designed to automatically maintain a Constant Voltage level. A voltage regulator may use a simple feed forward design or may include negative feedback. It may use an ElectroMechanical mechanism, or Electronic Components. Depending on the design, it may be used to regulate one or more AC or DC voltages. Electronic voltage regulators are found in devices such as computer Power Supplies where they stabilize the DC voltages used by the processor and other elements. In automobile Alternators and central Power Station Generator plants, voltage regulators control the output of the plant. In an Electric Power Distribution system, voltage regulators may be installed at a Substation or along Distribution Lines so that all customers receive steady voltage independent of how much power is drawn from the line. Automatic Voltage Regulator : Generators, as used in power stations or in standby power systems, will have automatic voltage regulators (AVR) to stabilize their voltages as the load on the generators changes. The first automatic voltage regulators for generators were electromechanical systems, but a modern AVR uses solid-state devices. An AVR is a feedback control system, that measures the output voltage of the generator, compares that output to a set point, and generates an error signal that is used to adjust the excitation of the generator. As the excitation current in the field winding of the generator increases, its terminal voltage will increase. The AVR will control current by using power electronics devices; generally a small part of the generator's output is used to provide current for the field winding. Where a generator is connected in parallel with other sources such as an electrical transmission grid, changing the excitation has more of an effect on the Reactive Power produced by the generator than on its terminal voltage, which is mostly set by the connected power system. Where multiple generators are connected in parallel, the AVR system will have circuits to ensure all generators operate at the same Power Factor. [1] AVRs on grid-connected power station generators may have additional control features to help stabilize the electrical grid against upsets due to sudden load loss or faults.

The economic life of our stabilizers is easily 15 - 20 years. So, you can plan stabilizers as per your running load, keeping in mind your future expansion plans. VOLTAGE VARIATION: Voltage variation is a common phenomenon all over the country. Generally voltage is low during daytime and high during the night hours. Moreover on holidays, peak hours, rainy days and when the agricultural load is switched off, the voltage rises quite sharply - which is more dangerous. Electrical equipments are designed for 230 Volts (single phase) or 400 Volts (3-phase) and operate with optimum efficiency at its rated voltage. 90% of industrial load consists of motors. Electric Motors draw considerably high current at HIGH voltage and increase energy consumption, increase MDI and reduce power factor etc. These excessive power losses of motors generated at higher voltage results in their premature failure. Similar is the case with Bulbs and Tubes, when voltage increases above 230 Volts. For example, at 270 Volts, the power consumption of 60W-bulb increases almost 40% and the life of bulb reduce from normal 1000 Hours to mere 100 Hours only (as per analysis report of ISI mark bulb manufacturers). The industrial units having high failure rate of electrical equipments i.e. Electric Motors (particularly smaller rating motors up to 7.5 HP), Bulbs, Tubes, Chokes, Contactor coils etc., should verify that it may be due to Higher Voltage. We have supplied number of AVCs to different industries and our clients have confirmed the under noted advantages after installing our AVCs. 1) Up to 60% Reduction in Breakdown of Electrical Equipments 2) 5 - 10% Savings in Electricity Costs (up to 30% on lighting load) 3) Reduction in MDI by 10 - 15% 4) Attractive Pay-back period of 6 - 12 months 5) Improvement in Power Factor 6) Uniform quality of end product & Improved Productivity of the plant 7) Depreciation @ 80% from Indian Income Tax Act. PAY-BACK PERIOD: Owing to its high efficiency (~99.5% in avg. running conditions) and associated benefits, the payback period for ARZOO’S make AVC is typically between 6-12 months, depending upon the number of working hours and duration of high voltage.

Servo Controlled Voltage Stabilizer : The Servo Stabilizers uses an advanced electronic servo-motor concept to control a motorized variable transformer. Because of the motorization, there is a small delay in voltage correction. However, output voltage accuracy is usually ± 1% with input voltage changes up to ± 50%. These machines are not affected unduly by power factor or frequency variation. This type of technology tends to be extremely effective when considering large three phase applications, as it is able to maintain its accuracy of all three phases, both line to line and line to neutral, irrespective of input voltage balance and load balance at any power factor. They are also able to withstand large inrush currents, normally experienced with inductive loads. However due to the mechanics of this type of stabilizer, periodic maintenance is required.
