Electrical, SCADA/Instrumentation & Controls

Ribway’s Electrical and Instrumentation Group offers a full range of electrical and control expertise from the design of medium voltage and power distribution electrical systems to the design of low voltage control systems. Our electrical experience has included design of 10-100 MVA medium voltage substations, 120 to 480 VAC power distribution systems, motor control centers, adjustable frequency drives, and various types of lighting systems for municipal, environmental and transportation projects.

Electrical Design

Some of our electrical designs for medium voltage substations have been stand alone or multi-station line up utilizing loop or radial configuration. Our prior experience also includes upgrading trip relays from electromechanical type to solid state type. Designs for power distribution cover a wide gamut and include entire treatment facilities, remote service buildings, pumping stations, individual processes, office buildings, libraries, and laboratories.

Designs for motor control include devices such as variable frequency drives, soft start motor starters, delta-wye transition starters, auto transformer starters, DC motor starters, across the line starters, and servo-motor controllers. On prior projects, Ribway has conducted lighting evaluations to determine if lighting systems meet OSHA, IES, or LEED Standards.

I&C Experience

Our instrumentation and controls experience includes the selection of monitoring equipment, controls design for specific processes and systems, development of system functional descriptions, and programming. Instrumentation applications can be designed for sophisticated process monitoring or the measurement of simple parameters such as flow, pressure, level, pH, etc. Control systems can be designed for HVAC equipment, machinery, pumping systems, material feed systems, production lines, lighting, and motors. Designs can be developed using relays, PLC controllers or computer controls and can include interface networks such as Ethernet, ControlNet, Device Net and Data Highway. Ribway has performed programming services for PLCs, OITs, VFDs and HMIs. Programs have been developed for specific applications using RSLogix5 and RSLogix5000, RSView, Panelbuilder, Wonderware, iFIX, DriveTools and Modicon.

Deliverables

Design deliverables for electrical and instrumentation services include single line drawings, schematic drawings, plan and elevation drawings, panel, conduit and cable schedules, load charts, motor control center layout, wiring diagrams, process and instrumentation diagrams, and loop diagrams.
