ISO Certificate Setting high Standards as a consistent guarantee of the highest quality the company have achieved ISO 9001 certification for all its transformers. Regular internal and external quality audits ensure full and continuous conformity with the international standards. The company’s material and components suppliers are also required to satisfy these ISO standards. Quality control is earned out at each stage of production on a self-assessment basic. Each employee regards the next workstation as his customer and performs a series of quality checks before passing on a product down the line. The quality development department monitors all quality control documents and carries out its own additional inspection at strategic points in the production process. This system of checks and counter checks allows immediate action to be taken and modification to be made as required. All transformer tanks are tested before being released to the customer. Testing includes leakage test and pressure test. Routine Tests Following Routine Tests are made on every unit. Insulation Resistance Test Resistance measurement of winding. Turns Ratio Test Polarity and Phase relationship test No Load losses measurement Polarity and Phase relationship test Excitation current measurement Impedance voltage test Load loss measurement Dielectric tests includes applied voltage test and induced voltage test Leakage test of Transformer tank.
Type Test Type tests are made to prove to withstand the all irregularities in transmission/distribution line. T Power have in house facility to undergo temperature rise and impulse test conforming to latest national and international standard specifications. Other tests such as short circuit withstand tests (Dynamic & Thermal) are conducted at an independent govt. recognized testing laboratory at Central Power Research Institute, Bhopal/Bangalore, INDIA. Type tests are special tests. the test charges are to be borne by the customer.
