The Company

Established in 1973, Marsons is a leading player in thebusiness of manufacturing to Transformers based in India.Itis situated at national highway no.2,artoni ,agra (uttarPradesh). It is an ISO 9001 certified company having anextensive product range of Power & Distribution Transformers from 10 KVA to 20,000 KVA .Almost 400workers are employed in the industry.Marsons has a saleturnover of about 500 million.it meet the requirement of several state electricity board and it has its client in theforeign countries as U.K,Nigeria,Africa,yemen and Syria.Ithas well established in the market of Indian power sector. Itproducts are designed to meet the requirement of the globalmarket.
Design and R & D
MARSON'S Transformers are designed to meet all the latestnational and international standards, including IS, IEC, ANSI,BS, DIN etc. All Marson's Transformers are designed inaccordance with customers' specific requirement. High levelsof experience and expertise in transformer design andregular investment in research and development hasenabled Marson's to ensure excellence and competitivenessin quality, performance, price and delivery. Wide range of Transformers are tested and validated by authorized testinglaboratories. All material used are of best quality and of theclass most suitable for working under the specifiedconditions withstanding variations of temperature andatmospheric conditions. Above all, the design incorporatesevery reasonable precaution and provision for the safety of all those concerned in the operation and maintenance.

Marson's corporate thinking is driven by the commitment toquality.The complete in house manufacturing process helpsus to ensure optimum quality of the transformer. We havecomplete testing facility to test and check all the major raw-materials used in manufacturing the transformer. CRGOlaminations are cut and annealed in house to achieveminimum magnetic flux distortion. To ensure the best qualityof the Coils of the transformer, winding wires and strips arealso manufactured in house.Fabrication section ensure therobustness, quality and fine finish of the tank and radiatorsof the transformer.Marsons produces several types of transformer as corrugated wall panel,self protectedtype,ground mounted, hermetically sealed type with gascushion.

INTRODUCTION ABOUT TRANSFORMER
Transformer is an ac machine that transfers electrical energyfrom one electrical circuit to another without changingfrequency by the principle of electro magneticinduction.Since it’s basic construction requires no movingparts so it is often called the static transformer and it is veryrugged machine requiring the minimum amount of repairand maintenance.Owing to the lack of rotating parts thereare no friction or winding losses.Further ,the other losses arevery low so that the efficiency should be high.The efficiencyvaries from 97% to 99%.
OPERATING PRINCIPLE

The action of a transformer is based on the principle thatenergy may be efficiently transferred by induction from oneset of coils to another by means of varying magnetic flux ,provided that both the sets of coils are on a commonmagnetic circuit.The emfs are induced by the variation in themagnitude of flux with time.It is based on Faradays law of electromagnetic induction.
POWER TRANSFORMER
The term is used to include all transformers of largesizes(250kva and above) used in generating stations andsubstations for transforming the voltage at each end of apower transmission line.They may be single or three phaseand voltage rating of 220/11kv or in high voltage range.Theyare put in operation during load hours and disconnectedduring light load hours or operated on full load.So powertransformer are desined to have maximum efficiency at fullload(i.e.with iron loss to full load copper loss ratio of 1:1).
DISTRIBUTION TRANSFORMER
Transformer of rating upto 200kva,used to step down thedistribution voltage to a standard service voltage are knownas distribution transformer.They are kept in operation all the24 hours a day.In such transformer iron loss occur for all thetime where copper loss occur only when they areloaded.Therefore,distribution transformers should bedesigned with iron loss smaller in comparision to full loadcopper loss(say with iron loss to full load copper loss ratio1:3 .
