Quality Control


A continuous quality control program is carried out during production where certain preliminary tests are carried out to assure quality and confirmation to design calculations.

The final tests on fully assembled equipment guarantee satisfactory performance. Very few errors in workmanship and design get past these tests. They are the result of a great deal of work and investigation by many engineers associated with transformer production. Constant revision of tests is carried out, as more definitive data and sophisticated equipment become available.

The basic testing requirements and testing codes are set out in the national and international standards.
