Power system studies and full electrical design, all sealed by California licensed Professional Engineers. Short circuit, coordination, and arc flash are normally performed together because each depends on the one before it — and because the system model, which is the expensive part, only gets built once.
Arc Flash Study
Incident energy analysis, arc flash boundaries, NFPA 70E 130.5 risk assessment, and labels printed and installed.
Read moreShort Circuit Study
Available fault current at every bus, checked against what your equipment is actually rated to interrupt.
Read moreCoordination Study
Time current curves for every device path, so a fault on one branch stops one branch.
Read moreNFPA 70E Training
Onsite electrical safety and arc flash training with hands-on lockout/tagout.
Read morePower Factor Correction
Capacitor sizing and placement, with the harmonic study that should come first.
Read moreElectrical Design
Power distribution design for commercial, industrial, and institutional facilities.
Read moreWhy the studies belong together
The short circuit study establishes available fault current. The coordination study sets protective device behavior against that fault current. The arc flash study uses both to calculate how much energy is released and for how long. Buying them piecemeal means paying to build the same model more than once.
Additional power system studies
Three studies that are usually bought alongside the ones above, and are run from the same system model once it exists.
Load flow study
Steady-state analysis of how power actually moves through the system: bus voltages, line and transformer loading, losses, and power factor at each point. It answers whether the distribution system can carry a proposed new load, where the constraint sits, and what happens under alternate switching configurations or with a generator carrying the facility.
Harmonic analysis
Variable frequency drives, UPS systems, LED drivers, and rectifiers distort the current waveform. Harmonic analysis measures and models that distortion, checks it against IEEE 519 limits, identifies resonance between system capacitance and inductance, and sizes filters or detuned reactors where they are needed. It should be run before capacitors are installed — see power factor correction — because adding capacitance to a system with significant harmonic content can create a resonant condition instead of solving one.
Voltage drop analysis
Feeder and branch circuit voltage drop checked against NEC recommended limits, so equipment sees the voltage it was specified for. Usually part of a design package or a load flow study rather than something bought on its own.
Software
Systems are modeled in SKM Power*Tools and EasyPower. You receive the model with the report, so future changes can be evaluated without starting over.
Where we work
Based in Visalia, working throughout California. The modeling happens from the data; what has to be local is the site visit, and we travel for it.
