The IEEE Dielectrics and Electrical Insulation Society (DEIS) Malaysia Chapter collaborated with TNBR Labs to organize a Webinar entitled “Condition Assessment of Power Transformer by Electrical Diagnostic Testing”. The talk was held online via Cisco WebEx and was attended by around 100 participants.
In this talk, Ir. Ts. Dr. Mohd Aizam Talik (Head of Advanced Diagnostic Services TNBR) started with a quick introduction of power transformer components and detectable faults. Next, he explained about the basic routine electrical testing and the more advanced electrical testing such as Frequency Response Analysis, Dielectric Response and Partial Discharge. He also explained about OLTC advance diagnostic testing using dynamic resistance and vibro-acoustic measurement.
It is hoped that the experience and knowledge shared during the webinar are beneficial to all participants.
