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.

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.

Tools
All tools →Calculators that show their work and refuse to guess when a case falls outside what they cover.
-
AC Conductor Sizing
Ampacity, deratings, underground runs, voltage drop, overcurrent protection and bonding — with a traceable source for every number.
-
OCPD Sizing
Device ratings checked against the conductor they protect, including continuous-load factors.
