Online Engineering New Zealand hello@engineeringnz.org

Join the Electrical Engineering Group for a presentation by Dr Bhaba Das of Hitachi Energy on "Decarbonizing distribution transformers - Energy efficiency metrics used in New Zealand".

In addition to our Electrical Engineering Group members, we extend the invitation to members of the Institution of Engineering & Technology (IET) , the Institute of Electrical & Electronic Engineers (IEEE), and the International Council on Large Electric Systems (CIGRE).

This presentation will follow on from Bhaba’s recent co-authored article on energy efficiency metrics for distribution transformers that was recently published in Transformer Magazine Vol 9, Issue 2, 2022. The introduction of specific Minimum Energy Performance Standards (MEPS) of distribution transformers in the early 2000's represented a huge step forward in streamlining the Australian & New Zealand transformer market and directing it towards energy efficient solutions.  Almost two decades later Bhaba articulates why there is a need to relook at the existing metrics and update our specifications.  Evaluating transformers based on their global warming potential is no longer a "nice-to-have"!

Following the presentation Bhaba will be available to answer your questions.

The key learning outcomes of this presentation will be:

  1. Why are energy efficient distribution transformers needed?
  2. AS 2374.1.2 vs IEC 60076-20 Efficiency Standards
    • Comparison with Global Tiers
    • Efficiency at 50% load
    • Designs – Comparison
  3. Total Cost of Ownership – why include CO2 costs in distribution transformer specifications?
