For more than ten years, at UQAC, we have been equipped to offer a full range of analytical services and tests on transformers. The equipment is calibrated and regularly maintained. All tests are performed in accordance with appropriate American Standard for Testing Materials (ASTM) or International Electrotechnical Commission (IEC) procedures. The chairholder is a participating member of the ASTM D27 Committee and all laboratory personnel receive training from equipment vendors. One of our missions is to offer comprehensive testing services at competitive prices to manufacturers in the region. Results can typically be provided within 48 hours upon reception of samples.
