Just thought I would share some of the online technical guides which, I regularly use:

• ABB Pocket Book Switchgear Manual - The famous ABB manual is now online.
• ABB Softstarter Handbook
• AREVA PRAG (Network Protection & Automation Guide) - The ultimate relay and protection handbook. 
• Harmonics Causes and Effects - by the Copper Development Association

• Merlin Gerin, Electrical Installation Guide (According to IEC  60634) - Merlin Gerin's low voltage installation guide

I  will try to keep the above list updated as people add more guides to this thread.

Just thought I would share some of the online technical guides which, I regularly use:

• Merlin Gerin, Electical Instllation Guide (According to IEC  60634) - Merlin Gerin's low voltage installation guide, covering everything you need to know about low voltage installation.  This is one of the guides I use the most.
  
  
• ABB Pocket Book Switchgear Manual - The famous ABB manual is now online. 
  
  
  
• AREVA PRAG (Network Protection & Automation Guide) - The ultimate relay and protection handbook.  Previously the GEC relay application guide, AREVA has now made this great publication available online.
  
  

If you know of other similar guides, just add to this topic.

 

Just come across a better than average article on Harmonics:

Harmonics Causes and Effects by the Copper Development Association

If you want some general information on harmonics I think the above publication is a good starting point.

Another good guid:

ABB Softstarter Handbook

Thanks a lot of the website that youve given..
