Welcome to powerquality.sg

Welcome to powerquality.sg

Power quality isn’t a new word or term. It has been around for ages. However if one is to search around, there isn’t much information available with regards to this topic here in Singapore.
It is very much still a niche area in the local electrical engineering scene.

Hence, the birth of this blog/site. It is the author’s intention to fill this gap of information here in this website and at the same time a platform to share the author’s views & experiences gained in the subject.

The author is currently the Lead Engineer at Potentia Dynamics Pte Ltd, an engineering & consulting company.
