Eramosa Engineering has experience designing complete electrical distribution systems for both new and existing facilities. Our services include the design of high voltage incoming substations (25kV/13kV) including primary switchgear, secondary switchgear, transformers, standby power generation, plant-wide distribution systems at 4160V/600V as well as plant lighting and control systems. Our team of electrical engineers and technologists are ready to 
assist you in the building code application process and design
and implementation of any component of your electrical distribution

Eramosa Engineering can provide the following services to our clients, from conceptual design, through preliminary and detailed design, as well as start-up and commissioning services during the construction phase of the project.

Substation Design.
Our expertise in the design of power distribution systems starts at the incoming service from the local hydro authority where close coordination with their team and the electrical Authority Having Jurisdiction (AHJ) are required. Substation designs at 25kV and 13kV have been completed by our team for a number of new and upgraded facilities.

Plant-wide Electrical Distribution Systems.
The design of the secondary distribution system is critical to the reliability of the plant-wide distribution system. Our team has experience in the design of distribution systems at 4160V/600V for large-scale facilities including key electrical components such as switchgear, MCCs, motor control schematics, cable sizing, duct banks, grounding, surge suppression, standby power, and transfer schemes. On each project we review the secondary distribution system to select the most appropriate configuration for reliability of the system based on standard configurations as per IEEE Std.141-1993. Typical configurations include secondary selective designs to increase the reliability of the distribution system as well as the implementation of standby power equipment.

Lighting & Low Voltage Power.
Correct lighting levels based on the tasks to be performed by operations and maintenance personnel are a key element of plant design. Our team has extensive experience in applying lighting level design to all areas of plants and remote facilities.

Hazardous Locations.
Wastewater treatment facilities often include classified areas under the Canadian Electrical Code (CEC) requiring the use of correctly rated equipment and wiring to meet the requirements of the CEC and NFPA 820.
