Our electrical engineers have extensive experience designing electrical systems for new facilities and plant expansions. We can start at the utility pole or from existing transformers and switchgear.

Our project portfolio includes everything from stand-alone rack-mounted starter racks, VFDs, and Heater Power Panels (HPP) to complete Motor Control Centers with advanced network connectivity and modular Power Distribution Buildings or E-Houses. PTI produces code-compliant designs for electrical gear and power systems to meet your current and planned expansion needs.

We also support our clients by conducting Power System Studies, Short Circuit and Relay Coordination Studies, Arc Flash Studies, and determining Flash Hazard Protection Boundaries.

Arc Flash Study

PTI’s licensed electrical engineers provide arc flash studies for industrial and commercial facilities to help protect your employees and to meet the requirements of NFPA 70E.  A comprehensive Arc Flash Analysis must be completed and reviewed at intervals not exceeding five years or after making significant changes to your electrical systems.  

Principal Technology engineers conduct these studies and can assist your plant personnel in gathering the required technical data for your system, including:

  • Auditing or producing a Power Distribution One-Line Drawing
  • Gathering and documenting the size and ratings of your installed equipment 
  • Conducting Short Circuit and Coordination Studies to determine the incident energy and arc flash boundaries.
  • Determine what Personal Protective Equipment (PPE) is required based on the study results.
  • Producing Arc Flash Labels for each of your panels or enclosures. 
Modular Motor Control Center E-House

Modular Motor Control Center E-House

Plug and Play…. for industrial projects.   Added congestion to an already busy plant, minimizing interruptions to ongoing facility operations, reducing outage cost by maximizing work performed off-site…  These are just a few of the reasons clients opt for a modular construction approach to their projects.  

PTI has 25 years working with clients to achieve these goals.   One piece of this work is to modularize Motor Controls along with plant and safety control system.  These systems are pre-wired and pre-tested before they pass through the gate at your plant. 

Motor Control and Power Distribution Building

Power Distribution Center

Modular power distribution centers are an efficient way to provide a controlled environment manufactured quality without creating unnecessary congestion at an already busy construction site.  

Principal Technology engineers and designers provide design-only or design-build services to produce these modular systems.  Typical options include traditional HVAC, corrosive environment coatings, or purged and pressurized buildings suitable for Class 1, Div 2 hazardous areas.

Water Disposal Facility Motor Control and Power Distribution Rack

Water Disposal Facility Motor Control and Power Distribution Rack

Principal Technology electrical engineers and designers developed this 480 VAC, 600A power distribution rack which included multiple variable frequency motor drives, motor starters, low voltage transformers, breaker panels, process control panels, and UPS battery backup systems for a water disposal plant in West Texas.  

Our system integration and fabrication group also constructed and prewired the system before shipping it to the plant for installation.  PTI engineers routinely assist our clients with onsite construction, commissioning, and start-up support.  Design only or design-build; our engineers and designers are ready to tackle your project.
