INTEGRATED CONTROL SYSTEMS FOR PROCESS CONTROL & PLANT AUTOMATION
Paul Ewart Hi-Tech Company’s staff can participate in design and installation of Programmable Logic Controllers (PLC), Distributive Control Systems (DCS) for controlling plant processes, instrumentation loop diagrams, schematics, hardware and software implementation, as well as the training of personnel to operate these systems.
FEATURED PROJECT
As part of one facility expansion project, we evaluated existing power requirements together with the electrical needs for the expansion. To supply power adequately to the entire facility, the electrical distribution system was reinforced with a new 12,000 KVA primary substation of 115 KV to 13.8 KV and four 12 KV to 480 KV, 2,000 KVA secondary substations.
The motor control centers were sized and designed with conduits and wiring to the motor stations. Our services covered the selection of control and instrumentation devices, layout of control panels, instrumentation, and logic programming for process sequencing. We also calculated the lighting levels to determine the necessary number of lighting fixtures. We provided drawings showing associated switches, branch circuits, wiring, and panel schedules.
