This webinar will first provide an overview on the papers received and published in a recent PWRD's special issue called "Advances in Condition Monitoring and Assessment of Power Equipment". It will also share the impressions of the guest EIC on the R&D trends in this important area.

The webinar will then present the best paper selected from the special issue. The paper, entitled "Analytical Expressions to Link SCNF and OCNF of Transformer Windings to Their Inductances and Capacitances for 1-Φ, 3-Φ Y and Δ Configurations", establishes a mathematical relationship between transformer winding/core movement and the deviation of its frequency responses. This finding has the potential to facilitate a more meaningful interpretation of FRA (frequency response analysis) data, leading to improved transformer condition monitoring.

In the main part, a novel approach is presented to derive closed-form analytical expressions that connects harmonic sum of squares of natural frequencies (both SCNF and OCNF) of any winding configuration to its elementary inductances and capacitances. Expressions are derived for all 1-Φ and 3-Φ winding configurations.

Next, a sneak preview of an application of derived expressions to indirectly measure equivalent air-cored inductance (termed as Leq) of an iron-cored transformer winding, from measured FRA, is discussed. Experiments on 3-Φ, air-cored, 33 kV, 3.5 MVA winding setup are discussed. Results are cross validated by inductance measurements using an LCR meter.

Future thoughts on using Leq as an alternative to leakage reactance measured at 50/60 Hz to provide improved sensitivity for interpreting routine short-circuit test data is discussed. Finally, some insight on using derived expressions to locate radial/axial displacements in Y and Δ windings are very briefly presented.

Who would benefit from attending this webinar:
Researchers/Engineers interested in interpretation of measured FRA and possible novel uses of FRA data

You might have great ideas and research, but unless you can bring it all together for your reader, you won't have a strong technical paper. In this webinar, Prof. Saifur Rahman will highlight issues with paper structure, conference vs. journal papers, ethics, where to publish, open access, impact factor, etc. Providing an excellent foundational preparation for writing your paper.

This Webinar:

In recent years, new material and improved design led to development of larger and higher rating wind turbines. Offshore wind farms have introduced new engineering challenges. Expansion in offshore wind installation led to introducing the concept of winter lighting for the first time in IEC standards in 2018. Changes in Electrical Industry standards are being made to keep up with the fast pace of renewable energy development. The presentation gives an update on recent trends in wind energy business. An overview of the recent updates in IEC standards, Cigre working group on winter lightning, and NEC will be provided.

Who would benefit from attending this webinar:
Individuals interested in Renewable Energy Industry, companies working on lightning protection for offshore wind farms, individuals working on lightning and surge protection for wind farms.
