In-house testing laboratory supports routine, type and special tests in line with IEC, IS and utility-specific requirements. Testing is integrated across the manufacturing cycle, from incoming material inspection and in-process validation to final unit testing. Every transformer is validated through a defined test protocol before dispatch.
