Advanced Testing Facilities

The Testing process of Power Transformer involves a series of stringent tests and procedures conducted at different stages of manufacturing in ensuring the reliability, safety, and optimal performance in the electrical networks.

TAL EHV Laboratory has been assessed and accredited by NABL up to 400 KV, 500 MVA in accordance with the standards ISO/IEC 17025: 2017 for its competence of testing laboratories. NABL is an autonomous body setup under Ministry of Commerce & Industry Government of India (DPIIT) and is a constituent board of Quality Council of India (QCI). We have full- fledged plant machinery and Testing Equipments suitable for manufacturing up to 400 kV, 500 MVA.

Key Features of our Testing facility are:

• TAL's testing facilities are world-class, with independent test facilities in each manufacturing area equipped with modern instrumentation.
• Fully automated, computerized test benches employing advanced testing software for all routine, type and temperature rise tests, adhering to international standards.
• All Type, Special and Routine Tests (except for Short Circuit Test) are carried out (in-house) in accordance with International Standards like IS 2026 & IEC 60076.
• Short circuit tests undergo third-party testing at CPRI
• In-house Oil Test Lab, for Transformer Oil, as per IS 335/IEC 60296 & DGA testing
• 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
• TAL’s test lab has been assessed and accredited in accordance with the standard ISO/ IEC 17025:2017 for upto 400 KV, 500 MVA by National Accreditation Board for Testing Calibration Laboratories (NABL)
