5 star rating transformer manufacturers

Prestige Quality star rated transformers suppliers in africa, view 5 star rated transformer price

Star Rated Transformers such as the 5 star rated transformer is considered to be an energy efficient transformer. The 5 star rating transformer manufacturers started production of these products as a part of the Green Campaign. These are bee star rated transformers which carry standard specifications as per Bureau of Energy Efficiency, or shortly referred to as BEE.

The Bureau of Energy Efficiency, otherwise known as the BEE is an agency of the Government of India. The Bureau of Energy Efficiency was created in March 2002 under the provisions of India’s 2001 Energy Conservation Act under the Ministry of Power. The agency’s main function is to develop programs such as star rated transformers that will increase the conservation as well as efficient use of energy in India.

5 star rated distribution transformer is generally rated from star one to star five. These ratings are  based on their performance, although in the case of these transformers  star one is the segment where the loss is considered to be the highest and lowest loss segment would be defined as 5 star transformer specification.

The maximum losses equivalent to BEE 5 star transformer losses rating must not exceed the values at rated voltage as well as rated frequency which are permitted at 75 Deg. C. For instance, the indicated Max. Losses @ 50% load for a 5 star transformer socket would be 435 Watts and the Voltage ratio for the 5 Star Transformer would be 11000/ 433 V.

We are one of the leading suppliers, dealers and manufacturers of star rating transformer India.

We’ve accomplished 5-Star BEE names for these evaluations, with tests of each rating being Type Tested in a NABL Lab before accomplishing the Star Name. These transformers are majorly obtained by SEBs/DISCOMs & by Turnkey Companies executing projects on behalf of SEBs/DISCOMs.The notable highlight of the 5 star rating transformer is the truth that only add up to losses are indicated, both at 50% loading and at 100% loading, so that the manufacturer may utilize his plan skill and ideal materials to attain the given losses. Individual loss figures (no load loss and load loss) are not indicated.

The referred Indian Standard are IS1180 (part 1) Outdoor type three-phase distribution transformers upto and counting 200kVa, 11kV – detail, IS2026 (part 2). The standard evaluations secured beneath this pilot energy naming scheme is 16, 25, 63, 100, 160 and 200kVa and non standard evaluations from 16 to 200kVa.Star Rated Transformers are energy effective transformers begun as a “Green Campaign”. These are transformers that carry standard details as per Bureau of Energy Efficiency (BEE).

We are among the reputed organizations, highly engaged in providing an optimum quality range of 250KVA 5 Star Distribution Transformer.

For non standard rated transformer from 16 kVA upto 200 kVA which is not listed above

the total losses at 50% and 100% loading for a given non standard rated transformer is going to be determined by the following equations :

 

Where;

• K = kVA rating of the transformer L = losses
• ML = Maximum Losses for a given star rating.
• X0 = kVA rating of the Non Standard Rating transformer
• X1 = kVA rating of the Standard rated transformer below X0 X2 = kVA rating of the Standard rated transformer above X0
• L2 = Maximum Losses for a given star rating of standard rating transformer above X0 @  a particular loading.
• L1 = Maximum Losses for a given star rating of standard rating transformer below X0 @ a particular loading.
• MLX1 = Maximum Losses of X1 @ a particular loading for a given star rating.
