The IS 1180 (Part 1):2014  is a  revised ISS, which covers both sealed as well as non-sealed type distribution transformers with voltage of up to 2500 kVA. Further, the IS 1180 (Part 1):2014  also covers nominal system voltage up to and including 33 kV. Besides this the revision of the level 3 certificate in energy efficiency for domestic heating also covers single phase sealed type distribution transformer up to 25 kilo-volt-ampere rating and a nominal system voltage up to and including 33 kilo-volt-ampere.

Moreover, in this revised version i.e. IS 1180 (Part 1):2014 , the distribution transformers have been grouped under three different categories as follows – Energy Efficiency Level 1, Energy Efficiency Level 2 and Energy Efficiency Level 3. These levels have been categorised on basis of the maximum total loss.The energy efficiency level 3 transformer manufacturers in India have designed these transformers based on the Basic Insulation Level or referred to  in short as BIL consideration.

Accordingly, the other parameters will also be set for the energy efficiency level-3 specified in is 1180 (part-1) 2014 of a particular rating in order to achieve the desired performance as required by the end user. Hence, the existing guidelines have been reviewed and the following guidelines have been proposed for certification of Outdoor Type Distribution Transformers as per the standard IS 1180 (Part 1):2014 for those factories or for the energy efficiency level 3 transformer manufacturers in India .

Within the past decades, greenhouse gas (GHG) outflows and their impacts on our planet have ended up the focus of many governments, offices, companies and individuals. Energy generation may be a major supporter to GHG emissions. In expansion to broad efforts to create energy generation more environmentally neighborly, bringing down energy utilization inside most mechanical and commercial offices moreover could be a objective. As a result, accomplishing expanded energy efficiency levels for electrical equipment, including transformers, has ended up a need for numerous industry participants.Star Rated Transformers are Energy Effective Distribution Transformers with Star Rating Name issued by Bureau of Energy Efficiency(BEE).

The significant Indian standard for distribution transformers (DTs) IS:1180/1989 has been changed within the year 2014 as IS:1180 (Part1)/2014 by Bureau of Indian Standard (BIS) subsequently superseding IS:1180 (Portion 1 and 2)/1989 both for fixed and non-sealed sort. This standard advance prescribes numerous reviewing with respect to vitality effectiveness, i.e. three energy-efficiency levels: level 1, level 2 and level 3 of transformers comparing to 3 star, 4 star and 5 star named transformers separately, as endorsed by BEE (moreover as per CEA required rules)

Star Rating Distribution Transformers with Energy efficiency level 3 as per IS 1180:2014 (Part I)

• Maximum Ambient Temperature=45°C
• Oil temperature Rise: 35°C
• Winding Rise: 40°C
• Tap switch: NIL(For 16 KVA to 100 KVA)
• Type Of Winding Aluminum wound Off circuit Tap switch: +5% to -5% @ 2.5%(For 160 & 200 KVA)

• TOC (Total Owning cost) = IC+ (A X Wi ) +(B X Wc)
• IC = Initial cost (unit end cost without tax) of transformer as quoted by the bidder.
• Wi  = No Load losses quoted by the bidder in Watt
  Wc  = Full load losses at 75 °C quoted by the bidder in Watt
• A Factor = Cost of no load losses in Rs/ Watt
  B Factor = Cost of full load losses at 75 °C in Rs. / Watt

1. Measurement of winding resistance (at all taps if applicable) [IS2026 (Part1)].
2. Measurement of voltage ratio, polarity, phase sequence and vector group[IS2026(Part1)].
3. Measurement of short-circuit impedance (principal tapping, when applicable)
4. Load losses at rated current and normal frequency,at50 % and100 % load [IS2026(Part1)].
5. Measurement of no-load loss and current [IS2026(Part1)].
6. Measurement of insulation resistance [IS2026(Part1)].
7. Induced over-voltage withstand test[IS2026 (Part3)].
8. Separate-source voltage withstand test [IS2026(Part3)].
9. Pressure and vacuum test(as per IS: 1180-2014).
10. Oil leakage test(as per IS: 1180-2014).
11. Neutral current measurement, shall not be more than 2% of full load current (CEA Guideline 2008 clause no 34.9)
12. Oil samples (one sample per lot) to comply with IS 1866.
13. Measurement of no load losses and magnetizing current at rated frequency and at 90%, 100%and 112.5% voltage

In revised IS specification, losses for each rating for each category have been defined in three levels which are denoted by as follows;

• a) Energy Efficiency Level 1
• b) Energy Efficiency Level 2
• 3) Energy Efficiency Level 3

In each level maximum losses (No Load Loss + Load Loss) at 50% load & 100% load have been specified for each rating in all categories.

a) Three phase distribution transformers upto and including 200KVA, 11KV Class

b) Three phase distribution transformers Higher than 200KVA upto and including 2500KVA, 11KV Class

Further to above it is also observed that IS 1180 are now also applicable for 22KV & 33KV class transformers, losses values for 22KV & 33KV class transformers shall be applicable as per below clause:

• a) For transformers having voltage class above 11KV and upto and including 22KV, the permissible total loss value shall not exceed by 5% of the maximum total losses values mentioned in table a) & b) for three phase.
• b) For transformers having voltage class above 22KV and upto and including 33KV, the permissible total loss value shall not exceed by 7.5% of the maximum total losses values mentioned in table a) & b) for three phase.
• c) For transformers having voltage class above 11KV and upto and including 22KV, the permissible total loss value shall not exceed by 7.5% of the maximum total losses values mentioned in table c) for single phase.
