Industrial, Substation &
Distribution purpose - Upto 2MVA 22 KV naturally air cooled.
Instead of mineral oil, these transformers have air as the
medium of insulation and heat dissipation. These are
nonflammable, maintenance free transformers which can be
installed at the load centre in enclosed area. Bringing the HT
Line to the load centre reduces the line losses.
One of the main
differences from other types of transformers is that the load
currents contain higher harmonics due to the distorted waveform.
The converter to the transformer causes the distorted current
waveform. This has to be considered current leads to higher
losses & temperatures in the transformer. Network regulations
also require reduction of harmonic distortion.
The most common use for converter transformers is found in
applications such as:
• Variable speed drives (VSD)
• Aluminium electrolysis
• DC arc furnace
• Graphitizing furnaces
• Traction substations
• Copper refining
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. cleaned and each device undergoes appropriate
testing.
URJA makes all efforts
for up skilling and continual training of employees in order to
enhance their capabilities and competitive skills so that they
can achieve its Quality Objectives.
To engineering to perfection and meeting the exacting standards
of domestic and global customers and broadening its customer
base to include international markets as well.
To initiate quality up gradation, value addition and forward
integration steps to enhance global competitiveness.
To continually improve quality management systems to offer
product and services which meet the requirements of our
customers in the power sector.
To improve Customer satisfaction in terms of Performance,
Reliability & Timely Delivery.
To achieve continual improvement through a Management System
which meets the requirement of ISO 9001: 2000.
To establish objectives at all functions and levels and shall
review these objectives and take appropriate corrective and
preventive actions.
Testing means to us much more than meeting contractual and
standard obligations. Several in-house tests have been devised
by us to ensure quality and reliability in service. For this, we
have a variety of testing equipment, full fledged laboratory and
trained personnel.
Six or Twelve Pulse with
IPT (Double bridge construction), Up to 10 KA DC, Up to 33kV,
ONAN/OFWF cooling.
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.
