Power Quality Auditing in Snohomish, WA

Power Quality Audits & Electrical System Assessment

You see equipment failing early, power bills creeping up, or production line stalls that your electrician can’t diagnose. Often, the culprit isn’t obvious—it’s poor power quality. Voltage sags, frequency distortion, harmonic pollution, and phase imbalance silently degrade equipment and inflate utility costs.

A power quality audit reveals what’s actually happening in your electrical system. Phase 3 Electric uses professional-grade power analysis equipment to measure voltage, current, harmonics, and power factor across your facility. We deliver a detailed report with actionable recommendations—and a data-driven argument to justify the fix.

For Monroe commercial and industrial operations, a power audit often pays for itself in prevented downtime and reduced energy costs.

What’s in a Power Quality Audit

Baseline Measurement & Data Collection

We deploy power monitoring equipment at key points in your facility—main service entrance, branch panels, critical equipment circuits. The equipment records voltage, current, harmonics, power factor, and phase balance over a 7–14 day window, capturing your actual operating patterns.

Comprehensive Analysis & Reporting

Our analysis identifies:

• Voltage problems – Sags, swells, or phase imbalance that shortens equipment life
• Harmonic distortion – Nonlinear loads (variable frequency drives, LED ballasts, switching power supplies) that pollute the power supply
• Power factor issues – Reactive power that increases utility charges and strains distribution infrastructure
• Load imbalance – Uneven current across three-phase circuits, causing neutral current and transformer overheating
• Grounding defects – Improper grounding that creates shock hazards and equipment failures

Recommendations & Implementation Plan

Based on the data, we recommend fixes—capacitor banks for power factor correction, harmonic filters, isolation transformers, panel rebalancing, grounding upgrades, or equipment replacement. Each recommendation includes estimated cost, expected payback, and implementation timeline.

Frequently Asked Questions

What is a power quality audit, exactly? A power quality audit is a detailed electrical analysis of your facility using professional monitoring equipment. We measure voltage, current, harmonics, and other factors over a week or two to identify problems that degrade equipment and inflate energy costs.

How much does a power quality audit cost? A basic audit with measurement and reporting runs $1,000–$2,500 depending on facility size and monitoring duration. The audit cost is often recovered in the first few months through energy savings or prevented equipment failures. Call (425) 505-5596 for a quote.

How long does an audit take? Measurement takes 7–14 days (we leave equipment in place, it collects data automatically). Analysis and reporting take another 3–5 days. Total turnaround: 2–3 weeks from start to final report.

What are the signs of poor power quality?

• Equipment failures that don’t have an obvious cause
• Flickering lights or computer glitches
• Higher-than-expected energy bills
• Motors running hot or making unusual noise
• Frequent breaker trips with no obvious overload
• VFDs or sensitive electronics failing prematurely

If you see any of these, a power audit is worth considering.

How often should we do a power quality audit? If you’ve had an audit and implemented fixes, a follow-up audit every 2–3 years or after major equipment additions is good practice. If you’ve never had one and your facility has recurring electrical issues, schedule one now.

Real-World Example: Snohomish Manufacturing Facility

A Tye Street manufacturer was experiencing intermittent production line stalls. Their electrician couldn’t find the cause. They called Phase 3 Electric for a power quality audit.

The finding: Harmonics from nearby manufacturing equipment were distorting the voltage on the facility’s branch circuit, causing a sensitive control system to fault randomly.

The fix: We installed a harmonic filter on the problematic circuit ($3,200 investment).

The result: No more stalls. Line runs smoothly. In the first month alone, preventing downtime saved $8,000 in lost production. The audit and filter paid for itself.

This is exactly what data-driven decisions can do.

Why Snohomish Businesses Trust Phase 3 Electric for Power Audits
