A power quality study is a comprehensive evaluation of your electrical system's performance. Using Class A certified equipment (Dranetz HDPQ Plus), we measure voltage, current, harmonics, power factor, and other critical parameters over a minimum of one week to capture representative demand patterns. Your facility needs one if you experience unexplained equipment failures, premature motor burnout, overheating transformers, tripped breakers, or high energy bills. Many power quality problems are unnoticed — they don't cause immediate shutdowns but slowly degrade your equipment and increase operational costs.

The measurement period is a minimum of one week to capture a representative sample of your facility's electrical demand across different operating conditions. The complete process — from receiving your single-line diagram to delivering the final report with recommendations — typically takes 2-4 weeks depending on the complexity of your facility.

We exclusively use Dranetz HDPQ Plus family analyzers — Class A certified per IEC 61000-4-30. This is the highest accuracy classification for power quality instruments, ensuring our measurements are accurate, repeatable, and defensible in audits and regulatory reviews. Key capabilities include 10 MHz sampling rate for transient capture, simultaneous 3-phase + neutral measurement, GPS time synchronization, up to 1 year continuous recording, and automatic event detection. For analysis, we use Dran-View 7 software enhanced with our proprietary Python analytics tools for advanced statistical analysis beyond standard reporting.

We evaluate your facility against IEEE 519 (USA) — the standard for harmonic control in electric power systems, measuring voltage unbalance, current unbalance, Total Demand Distortion (TDD), individual harmonics, and Voltage THD. This standard has specific limits that your facility must comply with. Our reports clearly identify any violations and recommend corrective actions.

Real Power Quality Solutions is based in Eagle Pass, Texas and serves clients across Texas. We provide professional documentation, reports, and communication to support our industrial and commercial clients.

Any facility connected to the medium voltage distribution network can benefit, but the highest impact is typically in: Manufacturing Plants (VFDs, motor drives, welders generate harmonics that degrade power quality), Hotels & Hospitality (HVAC systems, elevators, and sensitive electronics), and Commercial Buildings (large LED lighting, UPS units, and data center equipment). If your facility uses variable frequency drives, large HVAC systems, or has sensitive electronic equipment, a power quality study is strongly recommended.

If we detect non-compliance with IEEE 519 standards, we don't just report the problem — we design the solution. Our process includes: diagnosis to identify the root cause, solution design to recommend optimal mitigation equipment (capacitor banks, passive filters, or active filters), frequency sweep analysis performed with every design to prevent electrical resonance, and installation support for the recommended solution.

The cost depends on several factors: the size of your facility, the number of measurement points required, and the complexity of your electrical system. We provide customized quotes after understanding your specific needs. Request a free initial consultation through our website to discuss your facility's requirements and receive a detailed proposal.

Several factors set us apart: Class A Equipment (Dranetz HDPQ Plus — the highest accuracy class per IEC 61000-4-30), IEEE 519 Compliance, Frequency Sweep Analysis included with every solution design to prevent resonance, and we are a Texas Registered Engineering Firm.

Our core service is the comprehensive power quality study with actionable recommendations. We provide post-study support to ensure recommended solutions are properly implemented and performing as expected. For facilities that require continuous monitoring, contact us to discuss your specific needs.
