WHO NEEDS A STABILIZER:
The industrial units having abnormally higher failure rate of Electrical Equipments such as bulbs, tubes, chokes, starter, contactor coils & motors (particularly smaller capacity motors upto 7.5 H.P.) Etc. Should verify that it may be due to HIGHER voltage. You may note down Hourly readings of voltage variation for few days. If you find that input voltage is above 230 volts single phase/400 volts Three phase even for few hours a day, then you definitely require a stabilizer.

HOW TO ACCESS HIGHER LOSSES & LOW POWER FACTOR IN INDUSTRIAL UNITS WITHOUT INSTALLING STABILIZER:

Note down hourly readings of current and voltage of one motor operating at constant load for 2-3 days. From the different readings you will observe that the current drawn by the motor is minimum at 390/400 volts as compared to the current drawn at other voltages. This means that power consumed by the motor is minimum at 390/400 volts.

Also note down hourly readings of voltage and K.W. from your Electronic Energy Meter for 2-3 days. From the readings you will observe that K.W. is minimum at 390/400 volts in most of the readings as compared to the higher voltage.

If you find that the above collected details are true then you will certainly have the advantages after installing the Servo stabilizer as mentioned on succeeding page 3

ADVANTAGES:

• Reduction in Breakdown of Electrical Equipments
• Energy Saving
• Improvement in Power Factor
• Reduction in MDI
• Uniform Quality of End Product
• 80% Depreciation as per Income Tax Act
