POWER QUALITY · DIAGNOSTICS · CRITICAL POWER

When the power is the problem, we prove it.

DarkHawk is an electrical consulting firm in Naperville, Illinois. We monitor, measure and find the root cause of power problems in facilities that can't go dark — then tell you plainly what to do about it.

CORE SERVICES

Power reliability for places where downtime isn't an option.

Unexplained trips, failed equipment, drives that fault for no obvious reason. We measure what's actually happening on your electrical system and trace it back to the source.

01Electrical arc between two metal panels

Power quality engineering

Sags, swells, transients and harmonics — captured, measured against IEEE 519 and EN 50160, then mitigated.

02Electrician testing an electrical panel with a multimeter

Diagnostics & troubleshooting

Root cause analysis on nuisance trips and repeat failures, instead of replacing parts and hoping.

03Electrical transformer in a power substation

Critical power systems

UPS, on-site generation and redundancy planning for environments that cannot go dark.

OUR APPROACH

We don't guess. We measure.

Instrument-grade analyzers on your service and your problem circuits, recording every disturbance. Then an engineer reads the data — not just a software report.

  • Find where it starts. Utility side or inside your building — the answer changes who fixes it and who pays.
  • Rule things out. Ground faults, supply problems, bad equipment. Knowing what it isn't matters as much.
  • Tell you what to do. Every study ends with actions, ordered by urgency, with an owner for each.

THE DARKHAWK DIFFERENCE

A stack of graphs isn't an answer.

Most power quality reports hand you data and leave you to interpret it. Ours start with the bottom line, explain what it means for your operation, and end with exactly what to do next.

CLIENT PORTAL

Your results, explained.

Every DarkHawk client gets a private dashboard with their findings, a power quality score, recorded events and a prioritized action plan — written for the people running the facility, not just the engineers.
