Tengyi Testing Workshop

Our testing laboratory, situated within our factory, spans over 1,000 square meters and is equipped to test 3 transformers simultaneously. With 2 independent three-phase test systems, high voltage AC test equipment, and impulse voltage generators for Lightning Impulse (LI) and Switching Impulse (SI) tests, we are capable of performing all routine, type, and special tests in accordance with IEC and IEEE standards for our entire product range, up to 600 MVA and 800 kV.

Our Power Transformer Test Bay has received ISO 17025 accreditation, confirming our laboratory’s competence. The National Accreditation Authority has granted this accredited status, enabling Tengyi to conduct both accredited laboratory and on-site testing of power transformers.
