STRONG R&D
TAL has strong R&D team having capabilities of
developing new products in house
All the products manufactured by the company
have been developed in-house including the 220
kV & 132 kV transformers
The company has a fully computerized design
office and all transformer designs are done on
the basis of in-house developed software
For mechanical design, Computer Aided Design
tools like AutoCad & Solidworks are used
extensively
Large number of TAL transformers have
successfully cleared Impulse Voltage Withstand
Capability tests at 3rd party, Government
accredited Laboratories like CPRI (Central
Power Research Institute)
TAL also has some of the largest no. of
transformers that have cleared 3rd party short
circuit tests, amongst companies of TALs size

TAL has a very strong, highly experienced design & engineering and R&D team capable of taking new challenges

Testing facilities
OVERVIEW
Independent testing facilities for Power and Disttibution transformers at both
Lucknow and Sitarganj plant.
TALs Test lab has been assessed and accredited in accordance with the
standard ISO/IEC 17025:2005 by National Accreditation Board for Testing
Calibration Laboratories (NABL).
All routine tests/Impulse test & Temperature rise tests as per IS2026/IEC60076
are performed in house using fully automated, computerized test benches &
advanced testing software. TAL can also conduct specialized advance tests
such as measurement of Partial Dischargge, SFRA etc. at its works.
Short circuit tests are conductted at CPRI (Indias leading, independent test
center).
Impulse voltage withstand ability tests are carried out through two impulse
generators (1600 kVp, 160 kJ and 900 kVp, 45 kJ) from Haefely, Switzerland
with expandable capacity to test transformers of 765 kV voltage class.
