Adverse Effects of Single Phasing
If your unit is suffering from low / high / unbalanced voltage, you need to install a stabilizer soon. Industrial units having acute / higher failure rate of Electrical Equipment such as bulbs, tubes, chokes, starter, contactor coils, motors etc., should verify that it may be due to voltage variation (esp. high voltage). You may note down hourly readings of incoming voltage for a few days continuously. If you find that input voltage is lower or higher than 230V (single ph) / 400V (3-ph) even for few hours a day, then you definitely require a stabilizer.

Jindal's AVC's not only stabilize incoming voltage fluctuations, but in the process also help save energy upto 30% and reduce breakdowns upto 80%. We ensures continuity in production and consistency in quality despite incoming voltage variations. Owing to its high efficiency and associated benefits, the pay-back period for the cost of our AVC is typically between 6 to 18 months, depending upon the nature and duration of load and the extent of voltage variation. And more often than not, it is simply avoiding a few minutes machine downtime or just one failure to recover the cost of the equipment.
Jindal’s AVCs are installed either along with the main Distribution Transformer / Panel to ensure stabilized voltage supply to entire plant & machinery / complex, or along with individual machines processes to hold voltage / current / power / temperature / lighting intensity constant. Our AVCs find wide application across all kinds of machines or industries / commercial / residential complexes.
