Voltage fluctuation is not a new problem and it can even cause permanent or temporary failure of load. Sudden voltage fluctuations can also reduce life span of several home appliances due to high or low voltage then it is actually required. There are many reasons because of which voltage fluctuates and one of the most common reason is sudden load change or faults in main power system. That’s why, it is important and must to supply right voltage, considering the importance of home appliances and need for protection. Voltage stabilizer is mainly used for maintenance of right voltage supply so that home appliances remain protected from under and over voltage. There are many servo voltage stabilizer manufacturers available in market nowadays, who deal in best and effective stabilizers offering number of benefits.
Need of voltage stabilizer – Although, there is no surprise in saying that voltage stabilizers are mainly used for providing right and stable voltage to different type of electrical appliances. The electrical equipment’s are designed for wide range of input voltage. So, depending on sensitivity working range of appliances are limited. In number of areas, dip or rise of voltage is quite common due to which the demand of stabilizer such as Shakti servo voltage stabilizer is increasing continuously. Therefore, voltage stabilizer helps in ensuring that fluctuation in voltage do not effect load of electrical appliance at coming power supply.
The working of voltage stabilizer is based on principle of transformer. Input current is connected with primary windings, while output current situation is connected with secondary windings. Electromagnetic relays are actually activated, when there is drop in voltage as it add number of turns in secondary winding. Thus, this help in giving higher voltage which compensate loss of outer voltage. While, on other side when there is rise in an incoming voltage reverse happens and as a result voltage in outer side remains unchanged.
Different types of voltage stabilizer
Automatic voltage stabilizer: The main use of this type of voltage stabilizers are mainly on oil rigs, emergency power supply, generating plants and so on. It is basically an electronic power device which is used for providing high voltage with out changing phase shift or power factor. These stabilizers are available in two different sizes, large size stabilizer remain permanently fixed on distributed lines, however small size stabilizer is used for protecting home appliances from voltage fluctuations. In case, if voltage of power supply is less in comparison with required range, then in such situation step-up transformers are used for stepping the level of voltage and similarly if voltage is more than required range, then it can be stepped-down with help of step-down transformer.
Servo controlled voltage stabilizer: This type of stabilizer is also known as servo voltage stabilizer as it works on servomechanism which is well known as negative feedback. This stabilizer use servo motor which help in enabling voltage correction. These type of stabilizers are mostly used for high voltage accuracy, with input voltage ranging from ±1 percent to ± 50 percent. The internal part of servo stabilizer incorporates control essential components such as buck boost transformer, servo motor, motor driver and auto transformer. In this type of stabilizer, one end of buck boost transformer is connected with fixed tap of auto transformer. While on other hand, other end is connected with moving arm which is controlled by servo motor.
Static voltage stabilizer: As its name suggests, static voltage stabilizer do not have any type of moving parts like servo motor mechanism in servo stabilizers. For achieving voltage it use power electronic circuit rather than variac as used in conventional stabilizers. The main benefit of using static stabilizer is that it can generate excellent voltage regulation and greater accuracy in comparison with servo stabilizers and most importantly its regulation is ±1 percent. This stabilizer consist of ICBT power converter, buck boost transformer, IGBT power converter, DSP based controller, micro controller and microprocessor. Microprocessor and IGBT converter help in generating appropriate voltage by pulse modulation technique and then the generated voltage is supplied to buck boost transformer.
In this technological world, the demand for advanced products like voltage stabilizer is increasing day by day. So, if you live in such area where voltage fluctuates a lot then it is better to invest in a stabilizer. For the same purpose, above explained are few best voltage stabilizers which you can prefer buying.
