Recommendation

Reduce temperature rise limits Due to frequent overloading in service, life

deteriorates.

Contributes to poor reliability.

The current temperature rise limits 50/550C over theambient of 500C of top oil and winding respectively.

Temperature rise limits revised to 35/400C over the

ambient of 500C of top oil and winding respectively.

Implication on cost average of 3%.

Similar changes helped GEB to reduce failure rate

from 27% to 20%.

Recommendation

Star rating plan

The star rating represents the loss level and will

represent the efficiency status.

Star 1 is current IS level and Star 5 will be

lowest loss specifications.

Star rating will represent total losses at 50% &100% loads and at 750C.

Recommendation

Energy efficiency labels

Manufacturers would conduct the test as per the

approved procedure register with BEE &display label on the transformer.

Label will display rated capacity, star rating and

maximum total losses at 50% and 100% loads.

No positive tolerance on the displayed label

value.

Work on BEE S & L programme on FTL was initiated on

08 September 2002.

ELCOMA was requested to spearhead the BEE S & L

Programme.

T-8 ( 36W ) & T-5 ( 28 watt ) Triband offers lumen

efficacy of 85 lumen per watt

VISION OF S & L PROGRAMME

Lighting industry should strive to improve lumen efficacy

of over 70 lumens per watt in about 5 years time.


24/34

24

In order to create market pull, the government could

buy only star rated products, i.e. the highest energy

efficiency products.

The standards should be futuristic since there is also

a time frame required for phasing out old products

and introduction of efficient products. A time frame of

2-3 years was suggested.

Labeling would be the first activity to be taken up in

these products.

VISION OF S & L PROGRAMME

MEETINGS

In first meeting of steering committee held on 27

September 2002,it was decided to form a Technical

Committee having following compositions:

Mr. R.Nandakishoreconvener, Philips India Limited

Mr. R.S.Mandal, Osram India Private Limited

Mr. S.K.Neogi, Phoenix Lamps India Limited

Mr. S.Ramasubramanian, Surya Roshni LimitedMr. Ramaswamy, BEE


26/34

The task of Technical Committee is to finalise:

a. Testing protocol

b. Technical parameters along with weightages forlabeling

c. Label design

d. Test laboratoriese. Challenge & Check testing protocol.

Tasks of Technical Committee


27/34

FTL Technical Committee Recommendations

For energy labeling 3 parameters should be considered which

would provide efficacy from both efficiency as well as life:

Lumens at 100 hrs.(initial lumens) Lumen/watt

Lumen depreciation @ 2000 hours Lumen/watt

Lumen depreciation @ 70 % life (3500) hours Lumen/watt.

Test Procedure: relevant BIS test procedures including

amendments

meet all the minimum requirements of BIS to qualify for labelling

BIS certification or a quality control certification, a

prequalification for labelling


28/34

28

For 18W we have considered 940 lumens in place of 1015lumens inBIS since this has been agreed in the last

meeting of the BIS.

Based on the visit of the technical team to the four

Laboratories, the recommendations of the technical

committee is to go for testing at NPL & ERDA after

ascertaining Proficiency testing in both the Laboratories.

Accreditation of NPL with NABL is under process.

The 3200 lumen output lamps (Triband) was also

included for testing and BIS has also agreed to go in for

the standards in the last meeting


( Continued)


29/34

10 lamps were tested at manufacturers laboratory as

well as ERDA to get comparative readings/calibration

before full scale testing begins (Proficiency Testing).

There were certain differences in the optical

measurements in the three laboratories but these are with

in the z score of proficiency testing.

Since the measurements are against a standard

reference lamp, it was felt necessary to ensure thequality of reference lamp. BEE to take up with NPL

The lighting industry had agreed to align with ERDA

Basis

Values for the 100 hours efficacy was worked out taking intoconsideration that all Wattages and their energy efficacy isreflected the star rating plan.

The values of IS with permissible tolerances for different

wattages were used to arrive at the boundaries.

Efforts were made to differentiate 20 W & 18 W, 40 W & 36W and halo phosphates and Tri phosphates

Star rating plan would ensure efficiency purchases.

The cut off % for these categories have been fixed in such away the categories of lamps operating with good qualitycontrol as well as above the minimum threshold would fall inthe appropriate levels.
