Substations, Transmission and Distribution
 
Our staff has provided engineering and design services on substations and transmission circuits of up to 138,000 volts for clients in Ohio, Indiana and Michigan.  We work closely with the client  from the initial feasibility study phase through final commissioning and operation to ensure that the project meets the requirements of the system and to bring the project to a successful completion.  
 
The substation projects employ state-of-the-art protective relaying, metering and control systems, and SCADA systems which are all integrated to provide the protection, control and monitoring needs of the facility.  Transmission lines are designed to meet system functionality as well as public safety and aesthetic requirements.
 
Along with the electrical engineering and design, PDG has in-house expertise in site and rights- of-way acquisition, site development, structural and civil engineering design, and landscape design to provide a complete project.
Facility Engineering


PDG’s expertise includes electrical power distribution, backup generation, control, instrumentation, grounding, lighting and service entrance design for utility, industrial, institutional and commercial facilities. Our designs meet the requirements of the NEC as well as requirements for the specific installation. PDG can assess the power needs and power use in your existing facility to determine what changes, modifications or upgrades using state-of-the-art equipment for power distribution and lighting would provide a more energy-efficient and cost-effective solution for your facility.
 
Electrical generation design for emergency/backup power supplies, including evaluation of the power distribution system, load evaluation, economical generator rating selection, transfer equipment, connection requirements and interface with the electric utility is a service that PDG provides clients in the utility, industrial, institutional and commercial market places.
Electrical Studies
PDG has experience in facility condition and assessment studies as well as system planning and feasibility andsystem master plans.  Load flow, short-circuit and voltage drop, and protective relaying settings services are also provided.  Our expertise also includes power supply studies, including system evaluation, load projections and power supply.  The ability to perform studies of your system along with the full-service design functions can provide all of the expertise necessary to assist your team in planning and implementing a complete and successful project.
