Before diving into deep, our organization wants to apprise you that Since 1967 Jindal’s is one of the prominent manufacturers of Servo Voltage Stabilizer, Transformer & Silicon-Power Rectifiers. Jindal’s Automatic Voltage Controller has been helping the industry from overcoming the problem of voltage fluctuation & equipment failure since the last four decades.
Servo Voltage Stabilizer’s Overview 
The main phenomenon of Servo Voltage Stabilizer is to maintain your voltage variation and provide a constant voltage for equipment to the accuracy of ± 0.5 to 1.0 %.
- Unbalanced Voltage: Generally, This type of problem is faced by industries due to a common transformer from where multiple consumers are drawn power.
- High Voltage or Surges: Surges might be generated by disconnection of large loads, increase the voltage at generating plant, atmospheric events, units located close to start a supply line, etc.
- Low voltage Or Sags: It may be caused due to undersized distribution lines, a connection of large loads to the network, ground faults, units located towards the end of a long supply line, etc.
The occurrence of the above phenomenon depends on the cause and is not easily predictable. Broadly, voltage is low during day time and high during the night hours. moreover, on holiday peak hours, rainy days and when the commercial/agricultural load is switched off, the voltage rises quite sharply.
Importance of Three Phase Servo Voltage Stabilizer
Let’s draw an analogy of a human body. Our body needs to maintain a constant temperature of 98.4 F to work effectively. Even a minor increase or decrease in body temperature can lead to further deterioration of one or more body parts.
Similarly, most Electrical types of equipment require a constant voltage supply of 400v to last longer & run efficiently. Electric motors draw considerably high at high/Low voltage, causing excessive power losses and resulting in their premature failure. Similarly, Bulbs/Tubes/luminaries could consume up to 40% more power at high voltage and may last for a mere 10% of their normal life.
Advantages of Three Phase Servo Voltage Stabilizer
- Up to 80% reduction in the failure rate of electrical equipment
- Energy-saving up to 10% (up to 30% on lighting load)
- Reduction in MDI
- Improvement in Power factor
- Uniform quality of end products
- Improves Productivity of the plant
- Depreciation @ 40% as per Income Tax Act (In India) being an energy-saving device.
- Improve the duration/life period of your equipment.
