• 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 in increased electrical distribution system losses.

ACase Study

on Lighting System in

Small Scale Industries


Replacement of existing 40 W FTL fixtures with 28 / 36W FTL with the use of Electronic Ballast in Tube Light Circuit

Installation of Lighting Fixtures

40 W FTL : 170 Nos. 150 W HPSV : 20 Nos.

INTRODUCTION


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.


We recommend to replacement of 40 W FTL by EnergyEfficient 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.

Recommendation & Saving Potential:


Saving Potential by replacing 150 W HPSV with 100 W MH:
