Observations :
•
Generally in Small Scale Industries, 1 HP to 20 HP IE-1
category motors have been installed.
•
It has been seen form the measured parameters that
almost 60 to 70% motors are running under loaded.
•
Most of the electric motors are designed to run at 50 to
100 percent of rated load. Optimum efficiency of
motors are usually near to 50 - 100 percent of rated load.
•
Under loaded motors, those loaded below 50 % of rated
load are inefficient and exhibit low power factor.
•
Low power factor results
distribution system losses.

SITE MEASUREMENTS



During the site work, we shall collect the details
of different types of fixtures i.e FTL,
HPSV/HPMV/MH etc.
By using the Lux meters, we shall measure the
lumens of different types of fixtures as per the
guideline of Bureau of Energy Efficiency, (BEE).
By using the power Analyzer, we shall measure
the total lighting load of the plant at different
phases of R,Y & B.
Striving for Excellence
Recommendation & Saving Potential:

We recommend to replacement of 40 W FTL by
Energy Efficient Tube Light T5 (28W) with Electronic
Ballast. Life span of T5 is higher than conventional Tube
Lights. Much higher output in lumens value against the
conventional tube light fittings.

We also suggest to replacement of 150W HPSV by 100W
MH due to longer life, high
efficiency,
fast
warm
up/Re-strike, superior cold starting, improve colour
uniformity, P.F. is higher compared to HPSV.
