The Institution Of Electrical Engineers has a Consultants Directory, try http://consultants.iee.org/. Search for "transmission" "power system" or similar. Contact me on dwraith@handsa.co.uk if you need further assistance.
Hazardous area classification and selection of equipment is a specialist area. Although I am not aware of relevant legislation in your Country/State, it seems to me that as a PE you cannot sign off the installation as you do not have the relevant experience and competence. This is not a...
You do not say if your main 400 volt supply has an earth connection. If it does then you should connect your earthing system to it. If not you have a TT system and you must provide an earth electrode. See IEE Regs Chapter 542.
The majority of British (and Irish) engineers would probably share your ignorance of the problem as LV systems other than solidly grounded are virtually unheard of in the UK and Ireland. American electrical engineers are more familiar with the problem as I believe that ungrounded LV systems were...
I am working on studies for an overseas client. He has 2 GE ATB-2 generators but no data and isn't happy with typical data.
Can anyone help me out with values for subtransient and transient reactances for actual machines, ratings 18824 kva and 21176 kva, 2 pole 13.8kV, 0.85 pf, 60 hz.
High resistance grounded systems are quite common in Europe, particularly in France. Hence Merlin Gerin, part of the Schneider Group, have a large range of solutions for ground fault monitoring. Try this link for more information. http://195.25.64.11/HomePage.htm
Over the years I have been involved in numerous arguments concerning the efficacy of the steelwork of offshore platforms as the return path for ground fault and lightning current. Does anybody have any as-built measurements of impedance of platforms or modules, eg the resistance from one end of...
