The CIGRE/CIRED/UIE joint working group C4.110 report on “voltage dip immunity of equipment and installations” is out and can be downloaded from the following link: http://www.uie.org/node/401.
The report summarises on the following:
Aspects of voltage sag characteristics that equipment manufacturer should account for and test especially during equipment development;
Recommendations on equipment testing for voltage sags;
Industrial process immunity assessment to voltages sag problems;
Proposal for a classification of equipment based on voltage-dip immunity.
A small part of my doctoral research ‘process immunity to voltage sags’ work contributed to this report.
I have had an opportunity to meet Alex McEahern and talk to him during his visit and meeting with my PhD academic supervisor Prof. J V Milanovic. It was a pleasure talking and listening to his ideas, work and his company ‘Power Standards Lab’.
