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.

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.

Introduction to Stabilizer: The embedding of microprocessor chip technology and power electronic devices in the design of intelligent AC voltage stabilizers (or automatic voltage regulators (AVR)) led to produce high-quality, stable electric power supply in the event of significant and continuous deviation of mains voltage. As advancement to the conventional relay type voltage stabilizers, modern innovative stabilizers use high performance digital control circuits and solid state control circuitry that eliminates potentiometer adjustments and allows the user to set voltage requirements through a keypad, with output start and stop facility. What is a Voltage Stabilizer? It is an electrical appliance which is designed to deliver a constant voltage to a load at its output terminals regardless of the changes in the input or incoming supply voltage. It protects the equipment or machine against over voltage, under voltage, and other voltage surges. Why Voltage Stabilizers Are Needed? Generally, each and every electrical equipment or device is designed for a wide range of input voltage. Depending on the sensitivity, the working range of the equipments are limited to a specific values, for instance, some equipments can tolerate ± 10 percent of the rated voltage while others ± 5 percent or less. The voltage fluctuations (rise or dip of the magnitude of rated voltage) are quite common in many areas, especially at terminated lines. The most common reasons for voltage fluctuations are lighting, electrical faults, faulty wiring and periodic turning off the device. These fluctuations create mishap to the electrical equipments or appliances Servo Controlled Voltage Stabilizers These are simply termed as servo stabilizers (work on servomechanism which also known as negative feedback) and the name suggests it uses a servo motor to enable the voltage correction. These are mainly used for high output voltage accuracy, typically ±1 percent with input voltage changes up to ± 50 percent. The figure below shows the internal circuit of a servo stabilizer which incorporates servo motor, auto transformer, buck boost transformer, motor driver and control circuitry as essential components. In this stabilizer, one end of buck boost transformer primary is connected to the fixed tap of the auto transformer, while other end is connected to the moving arm that is controlled by the servo motor. Secondary of the buck boost transformer is connected in series with incoming supply which is nothing but stabilizer output. Electronic control circuit detects the voltage dip and voltage rise by comparing the input with built-in reference voltage source. When the circuit finds the error, it operates the motor that in turn moves the arm on the autotransformer. This could feed the primary of buck boost transformer such that a voltage across the secondary should be the desired voltage output. Most servo stabilizers use embedded microcontroller or processor for the control circuitry to achieve intelligent control. These stabilizers can be single-phase, three-phase balanced type or three-phase unbalanced units. In single phase type, a servo motor coupled to the variable transformer achieves the voltage correction. In case of a three-phase balanced type, a servo motor is coupled with three auto transformers such that stabilized output is provided during fluctuations by adjusting the output of the transformers. In an unbalanced type of servo stabilizers, three independent servo motors coupled with three auto transformers and they have three separate control circuits. There are various advantages of using servo stabilizers compared with relay type stabilizers. Some of these are higher correction speed, high precision of stabilized output, capable to withstand inrush currents, and high reliability. However, these require periodic maintenance due to the presence of motors.
Here is a smart way to reduce 10% to 20% of your electricity consumption monthly. This new innovative device Auto True Micro Power Saver (ATMPS) can filter & Stabilize the supply voltage while improving the efficiency and power factor of your electricity consumed. This Auto True Micro Power Saver (ATMPS) Device is able to store electricity for 5 to 10 seconds and release it for use doing downside voltage. It can also improve safety by reducing the overheating of electrical wiring, hence reducing the size of wiring an copper loss, low & high voltage protection, earth leakage & delay on circuit which protect your electronic & electrical appliances and improve their life. (Precaution should be observed here, this does not imply that attaching multiple units of the power saver will drastically reduce power consumption in all cases. Please consult a trained electrician if advice is necessary.) Most Commercial / Industries have consistently shown that one unit of the Power Saver will save 3 to 4 kWh per day, based on electrical consumption of 30 kWh per day. The amount depends on few factors such as the type of electrical appliance use, the amount of electrical use and location. Places near to shops, restaurants and light industries where voltage supply is unstable and fluctuating will see higher savings. In addition to extending the life span of appliance motor, this device also reduces the reactive power generated by inductive loads. It helps the utility companies by eliminating interference to the power supply. The ATMPS is a microprocessor based system, displays the Electrical parameters like Voltage. Features: • Save Electricity upto 20% . • Improve Power Factor . • Reduce Transmission Loss . • Eliminates overheating of wiring and appliances . • Protect against surges and spikes . • Stabilizes voltage . • Input Voltage Range : 200V to 270V (P-N). • Output Voltage : 230V (P-N). • Type of Machine : 1 / 3 Phase Unbalanced Units. • Efficiency : More than 98% at full load. • Output Wave-form : No distortion input waveform i.e sine wave 60 V/ Second. • Maintenance Free. • Increases the life of your electronic appliances . Technical Aspect: There are two components of power: Reactive Power And Working (Real) Power. Reactive power (KVAR) is used to create Electromotive Force(EMF) in the inductive loads in your home and business. This power performs no "real" work. Working power (KW) is the power that performs the function of the load. These two components combine to formulate Apparent Power (KVA), the total power which the load consumes. Apparent power is equal to the square root (sqrt) of (KW)^2 +( KVAR)^2. Power Factor is the ratio of working power (KW) to apparent power (KVA). In other words looking at all the power that a load consumes, how much of it (percentage wise) is used to perform the real work.
