PES Day 2020 Webinar: Insulation Testing with Very low Frequency
Insulating materials are the backbone of any electrical power apparatus (any voltage level). Especially, in MV and HV apparatus they are more prone to degradation due to lack of on-time condition monitoring, and predictive maintenance. The testing could be destructive and non-destructive. Measuring and quantifying the dielectric dissipation factor of such insulation is considered to be non-destructive testing.
A talk on such type of testing at very low frequency will be presented by Mr. Sayidul Morsalin and as a presenter and A/Pof Toan Phung as guest speaker. Both of them belong to the energy system research group UNSW. The webinar details to attend the talk are below.
In conjunction with IEEE PES DAY 2020, IEEE UNSW Student Joint Chapter of PELS/IAS/PES in collaboration with IEEE UNSW Student Branch would like to invite you to participate in an online Research Webinar via Zoom Meeting, the details of which are as follow:

Insulation Testing with Very low Frequency
Very low frequency (VLF) high voltage excitation has been considered as a promising diagnostic tool to assess the electrical insulation condition. The word “VLF” stands for testing the materials/equipment at 0.1 Hz frequency or lower. Due to the significant reduction of reactive power, the testing method has emerged as a promising alternative to the conventional AC testing of 50/60 Hz. To date, with the VLF diagnostic testing, there is no reasonable interpretation to explain the physical characteristics of electrical insulation, while testing at power frequency promotes a well documentation. Therefore, it is of interest to understand the material’s dielectric behaviour and physical phenomena under VLF test voltage and analyse the results with suitable modelling.
Biography:
Sayidul Morsalin is with the Energy Systems Research Group at the School of Electrical Engineering and Telecommunications, University of New South Wales (UNSW), Sydney, Australia. He is now waiting for his PhD Degree and received Master of Research (MRes) degree with the Higher Distinction from Macquarie University, Australia in 2016 and the B.Sc. degree with second-top position from the Chittagong University of Engineering and Technology, Bangladesh in 2013. His research interests include condition monitoring and asset management of HV systems, energy integration and management, smart grid aspects, internet of energy etc.

Biography:
A/Prof. Toan Phung received the Ph.D. degree in electrical engineering from the University of New South Wales (UNSW), Sydney, Australia, in 1998. He has over 30 years of practical research/development experience in partial discharge measurement and analysis, and in online condition monitoring of high-voltage equipment. Much of his work has involved collaborative projects between UNSW and Australian power utilities. He is currently an Associate Professor with the School of Electrical Engineering, UNSW. His research interests include electrical insulation (dielectric materials and diagnostic methods), high-voltage engineering (generation, testing, and measurement techniques), electromagnetic transients in power systems, and power system equipment (design and condition monitoring methods).
