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.

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.

Constant Voltage Transformer: The Ferroresonant Transformer , F erroresonant Regulator or C onstant-Voltage Transformer is a type of saturating transformer used as a voltage regulator. These transformers use a tank circuit composed of a high-voltage resonant winding and a Capacitor to produce a nearly constant average output voltage with a varying input current or varying load. The circuit has a primary on one side of a magnet shunt and the tuned circuit coil and secondary on the other side. The regulation is due to magnetic saturation in the section around the secondary. The ferroresonant approach is attractive due to its lack of active components, relying on the square loop saturation characteristics of the tank circuit to absorb variations in average input voltage. Saturating transformers provide a simple rugged method to stabilize an AC power supply. Older designs of ferroresonant transformers had an output with high harmonic content, leading to a distorted output waveform. Modern devices are used to construct a perfect sine wave. The ferroresonant action is a flux limiter rather than a voltage regulator, but with a fixed supply frequency it can maintain an almost constant average output voltage even as the input voltage varies widely. The ferroresonant transformers, which are also known as Constant Voltage Transformers (CVTs) or ferros, are also good surge suppressors, as they provide high isolation and inherent short-circuit protection. A ferroresonant transformer can operate with an input voltage range ±40% or more of the nominal voltage. Output power factor remains in the range of 0.96 or higher from half to full load. Because it regenerates an output voltage waveform, output distortion, which is typically less than 4%, is independent of any input voltage distortion, including notching. Efficiency at full load is typically in the range of 89% to 93%. However, at low loads, efficiency can drop below 60%. The current-limiting capability also becomes a handicap when a CVT is used in an application with moderate to high Inrush Current like Motors, Transformers or Magnets. In this case, the CVT has to be sized to accommodate the peak current, thus forcing it to run at low loads and poor efficiency. Minimum maintenance is required, as transformers and capacitors can be very reliable. Some units have included redundant capacitors to allow several capacitors to fail between inspections without any noticeable effect on the device's performance. Output voltage varies about 1.2% for every 1% change in supply frequency. For example, a 2 Hz change in generator frequency, which is very large, results in an output voltage change of only 4%, which has little effect for most loads. It accepts 100% single-phase switch-mode power supply loading without any requirement for derating, including all neutral components. Input current distortion remains less than 8% THD even when supplying nonlinear loads with more than 100% current THD. We Arzoo Energy with the Experience of more than 16 years as the manufacturer of many Electrical Products are the known manufacturer of Constant Voltage Transformers. SAVE POWER,SAVE WORLD

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.
