Power Distribution and Controls

Three dimensional electrical gear, bus duct and cable tray design;

• System interferences are avoided due to integration with three dimensional drawings of equipment, duct work and piping.
• Change orders are minimized due to avoidance of interferences and due to minimal field design modifications.

Detailed design of three phase power distribution for medium voltage systems (5 kV), 480 volt systems. Site and layout specific design of underground distribution, bus duct distribution, cable tray distribution and conduit distribution.

Specification and detailed design of primary power distribution, transformer installation and grounding grid. General criteria design of main incoming primary power services.

Detailed design of single phase power distribution and Ethernet/SCADA connections. SCADA and line controls design, installation and start up.

Experience in design of LEED certified facilities.

Calculation and specification of interrupting current rating requirements for electrical distribution equipment and for vendor equipment.

Design of power distribution systems to minimize arc flash risks and interrupting current risks at lowest capital equipment and installation costs.

Sample capital and operating cost savings initiatives;

• Evaluate electrical loads on individual services to determine the return on investment for power factor correction devices

• Design and installation of 4160 volt services in situations where motor sizing is sufficient to allow medium voltage service and where installation savings are sufficient to offset capital costs.

• Design power distribution system such that a tie-break switch (or switches) is installed to prevent a facility shut down due to a loss of a single main service (where multiple services exist).

• Logical design of power distribution such that all components of individual lines are serviced from the same main.  Shut down of multiple lines is avoided.
