The difference between the High Heat Value (HHV) and the Low Heat Value (LHV) is the Latent Heat of Vaporization (Evaporation). For natural gas it's about 10%. How about for landfill gas?
Given a generator 1.6MW 480Y/277V 60Hz and a GSU transformer with primary and secondary windings wye connected, neutral internally tied and solidly grounded.
What is the best method of grounding and minimum protection (relaying) necessary for the generator?
Some copper busbars being used on switchgears are pre-fabricated with slots/holes for ease of installation and interconnection. Example is a 1/4" x 4" square busbar with 3-slots in a row/column. The size of the slots is about 1/2" x 1" (oval shaped). Obviously, these slots reduce the cross...
Any technical info on why is it necessary for the cross-current transformer (CCT) to be used for paralleling multiple generator sets to be manufactured from the same batch?
Given a 2MVA 480V (delta)/12470V (wye-grounded) generator step-up transformer that will be interconnected to the utility. How to determine the size (rating & quantity) of PT's & CT's in the primary for 27, 59, 81O/U and 67N protective relaying? Is there any literature for this? Also, what is the...
