If your unit is suffering from low / high / unbalanced voltage, you need to install a stabilizer soon. Industrial units having acute / higher failure rates 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-phase) even for a few hours a day, then you definitely require a stabilizer.
