Power plant electrical, instrumentation and control systems are the focus of DP Engineering’s Electrical and Instrumentation & Control Engineering team.  Though medium and low voltage systems within the power block make up the majority of our engineering work within a station, we provide engineering services for the switchyard as well.  Electrical and Instrument & Control Engineering is the lead discipline for many projects while supporting mechanical-led and fire protection-led projects as well.

Electrical and Instrument & Control Engineering is the lead discipline for many projects while supporting mechanical-led and fire protection-led projects as well.  We endeavor to deliver compliant and cost-effective engineering solutions to our clients, from studies to seek the best solution, to equipment sizing and specifications, through conceptual and detailed design and testing.  Throughout the engineering process we work with supporting and supported engineering disciplines and keep our clients’ stakeholders informed and involved as they desire.  Our expertise includes areas of the “physical” – cabling, relays, motor control centers, relays, digital and analog controls, computers; “analytical” – circuit analyses (ETAP), protective device coordination; and of “compliance” – Codes, standards and the Owners’ licensing bases.  Our electrical and instrumentation & controls engineering staff maintain our technical edge through continuing education and service to industry organizations including IEEE and ISA.

Areas of service and expertise include:

  • Emergency Diesel Generators (obsolescence, regulatory compliance, mechanical, electrical and governing system controls)
  • Turbine Generators (power up-rate, mechanical and electrical controls)
  • 480V Switchgear, and MCCs (circuit breaker and bucket replacements, coordination studies, obsolescence)
  • Protective Relaying
  • Inverter and Battery Chargers (Including Swing Inverters)
  • Large Electric Motors
  • Cathodic Protection
  • Electrical calculations and analysis (protective device coordination studies, load flow, fault studies, ETAP)
  • Physical electrical design (cabling, raceway, MCCs, Switchgear, Load Centers)
  • Layout and design of electrical distribution systems
