Energy Study Project Example - Pope and Talbot

CLIENT: Pope & Talbot
LOCATION: Halsey, Oregon
The scope of this project was to provide the plant electrical engineer with an
existing load survey, a coordination study, fault current study, and an updated oneline
diagram for the existing plant electrical power distribution system. Field work
included collecting electrical equipment and motor nameplate ratings and
recording existing loads with a Dranetz Power Demand Analyzer. This data was
then compiled in a computer database and used as input data for the EDSA
(Electrical Distribution System Analysis) computer software. EDSA and ACAD
were used to calculate load flow, fault current, and to plot coordination curves.

The complete report included the following:

• Load survey summary and recommendations
  
• Coordination study summary and recommendations
  
• Fault current analysis summary and recommendations
  
• Equipment rating data base
  
• EDSA load flow calculations
  
• EDSA protective device coordination curves
  
• EDSA fault current analysis calculations
  
• Detailed plant one-line diagram

Evergreen Engineering provided the services of field collection of name plate
data, field collection of Electric Energy Demand, field confirmation of distribution
equipment configuration, compilation of data in computer data base program, and
input data to EDSA programs, the complete above mentioned report, coordination
curves and one-line diagram.
