Power systems studies and design.

Engineering for nuclear, heavy industrial, and utility-interface projects. Studies that stand up to review, designs that hold together on site, and calculations someone else can follow.

UTILITY 52 MAIN FEEDER 1 FEEDER 2 FEEDER 3 BUS
Everything downstream depends on getting the bus right.

Studies

  • Short circuit

    Fault duties across the system, and equipment withstand ratings checked against them.

  • Protection & coordination

    Settings for devices in series, and the fault currents at which selectivity is lost.

  • Arc flash

    Incident energy and approach boundaries, driven by the coordination study rather than assumed clearing times.

  • Grounding

    Ground potential rise, touch and step potentials, gradient control, and coupling to nearby structures.

  • Load flow

    Steady-state voltages, transformer and cable loading, capacitor and tap requirements.

Design

  • Power distribution

    Single-line development, transformer and switchgear selection, feeder and bus sizing from low voltage through medium voltage.

  • Cable systems

    Conductor sizing, duct banks and direct burial, shielded medium-voltage cable, raceway and tray design.

  • Grounding & bonding

    Station grids, equipment bonding, and the interface between plant steel and a nearby transmission structure.

  • Control systems

    Control schematics, separation of instrumentation from power, and interference mitigation near variable-frequency drives.

Calculators that show their work and refuse to guess when a case falls outside what they cover.

  • Low voltage & medium voltage

    AC Conductor Sizing

    Ampacity, deratings, underground runs, voltage drop, overcurrent protection and bonding — with a traceable source for every number.

  • Overcurrent protection

    OCPD Sizing

    Device ratings checked against the conductor they protect, including continuous-load factors.
