Power System Studies
Load Flow Analysis
Steady-state power-flow studies that verify voltage regulation, conductor sizing, and transformer loading at every operating mode.
Overview
Load flow tells you whether your facility will operate within design limits at every plausible loading and switching scenario: full-load summer peak, partial-load emergency mode, generator-only operation. We model the system in ETAP or EasyPower, evaluate voltage at every bus, transformer and cable loading at every branch, and identify violations of ANSI C84.1 voltage limits or thermal capacity before they manifest as field problems.
What's included
Scope of work
Full-load, partial-load, and emergency-mode load-flow cases
Voltage regulation evaluation at every bus per ANSI C84.1
Transformer, cable, and busway loading evaluation
Power factor and reactive demand assessment
Capacitor / reactor sizing recommendations
PE-stamped report with results tables and one-line annotations
Methodology
How the engagement runs
A consistent process means predictable timelines, fewer surprises, and a defensible record if anyone (AHJ, insurance, OSHA) asks how the work was done.
- 01
Load survey
Installed and projected loads compiled by zone with diversity factors applied.
- 02
Scenario definition
Operating modes defined: normal, generator-on-utility-off, partial bus, and so on.
- 03
Simulation
Newton-Raphson load flow run for each scenario in ETAP or EasyPower.
- 04
Compliance review
Bus voltages and branch loading compared to ANSI C84.1, equipment ratings, and NEC ampacity.
- 05
Recommendations
Conductor up-sizing, tap-changer adjustments, or PF correction recommended where needed.
Stamped
100%
Every deliverable PE-stamped by a licensed engineer in the project state. Across all 24 registered states.
