URJA’s Transformers Techniques

FOR IMMEDIATE RELEASE
Mumbai, Maharashtra, India, Republic of (Free-Press-Release.com) September 10, 2010 -- Earthing Transformers
Neutral Earthing transformers are normally provided in 3-phase system, which is without neutral and earth fault protection.
Neutral earthing transformer is having zig-zag (interstar) winding to achieve the required zero phase impedance. In addition an auxiliary winding can also be provided to meet the requirement of auxiliary power supply.
ONAN /ONAF cooling with conventional pressed steel radiators. The range includes up to 33 KV systems and as per the site requirements.

A high current furnace transformer is provided having the low-voltage windings arranged in a closed delta configuration within the transformer enclosure. Bus bar terminals are mounted exterior to the enclosure for providing electrical connection with the low-voltage windings.
Six or Twelve Pulse with IPT (Double bridge construction),
Up to 10 KA DC, Up to 33kV, ONAN/OFWF cooling.
Rectifier Transformers

A rectifier transformer circuit permitting six-phase double-wye operation with 120.degree. conduction, (without the use of an inter phase transformer), and providing any predetermined degree of phase shift. The transformer comprises a zigzag wye primary winding and a six-phase star secondary winding. By choosing the proper ratio for the turns of the zig and zag portions of the primary winding, any degree of phase shift can be obtained. The rectifier transformer is ideally suited for multiple-phase installations wherein several rectifier transformers are used, each providing a different amount of phase shift, without the use of separate phase-shift transformers.
Dry Transformers
Industrial, Substation & Distribution purpose
Manufacturing range Upto 2MVA 22 KV naturally air cooled.

A dry type transformer has an iron core, vacuum pressure resin impregnated high voltage windings and low voltage windings . The low voltage winding is constructed with conductors. Dupond nomex insulating material includes an apparatus to secure the windings in place during a vacuum and pressure resin impregnation process. The result is a coil that exhibits high short circuit protection due to the tightly bond conductors comparable to completely resin encased molded transformers at a substantially reduced cost.
Exports
Having achieved a good position in most of the product categories it is involved in, URJA increasingly looks to International business to power its growth volumes. Over the years, URJA’s Transformers have been exported to over many countries worldwide. URJA is exporter of power transformers and is aggressively pursuing export opportunities for all its product categories. The company's advantages of low production cost and high engineering quality makes its products an attractive choice and URJA is increasingly considered as an ideal source for transformers.

Today, URJA’s international operations are spread over all the continents in the world and its overall exports registered a commendable growth.
