POWER SYSTEM ANALYSIS
A power quality study measures and analyses the electrical characteristics of a power system to identify disturbances such as harmonics, voltage sags, transients, flicker, and power factor issues. The study determines the root causes of power quality problems and recommends corrective measures to protect sensitive equipment and ensure compliance with utility requirements.
Carelabs provides comprehensive power quality studies for commercial and industrial facilities across Dubai and the UAE. Using advanced power quality analysers, we measure harmonic distortion, voltage variations, transient events, power factor, and other parameters to identify and resolve power quality issues that affect equipment performance and utility compliance.
Modern facilities rely on sensitive electronic equipment, variable frequency drives, and digital control systems that are vulnerable to power quality disturbances. In the UAE, DEWA enforces strict harmonic limits and power factor requirements. Facilities with poor power quality face equipment malfunctions, premature failure, DEWA penalties, and increased energy costs from reactive power charges.
Our power quality studies are based on continuous monitoring data collected over a minimum seven-day period that captures all operating conditions. We analyse the recorded data against IEEE 519, IEC 61000, and DEWA power quality requirements to identify exceedances and determine root causes. Recommendations are backed by measurement data and engineering analysis.
What We Deliver
Measure and analyse harmonic distortion levels to identify sources and determine compliance with IEEE 519 and DEWA limits.
Evaluate voltage sags, swells, transients, and flicker to protect sensitive equipment from damaging power disturbances.
Assess reactive power demand and recommend power factor correction solutions to reduce DEWA penalties and energy costs.
Our Process
Review facility electrical drawings, identify known power quality issues, and determine monitoring locations for data collection.
Install calibrated power quality analysers at strategic locations throughout your electrical distribution system for continuous monitoring.
Monitor power quality parameters continuously for a minimum of seven days, capturing all operating conditions including peak and off-peak periods.
Analyse recorded data for harmonic distortion, voltage quality, power factor, transients, and other parameters against applicable standards.
Identify sources of power quality disturbances and determine their impact on equipment performance and utility compliance.
Deliver comprehensive report with findings, compliance status, and specific corrective measures including filter and PFC specifications.
EQUIPMENT PROTECTION
Poor power quality causes premature equipment failure, process interruptions, and data loss. Harmonics overheat transformers, voltage sags trip sensitive equipment, and low power factor increases energy costs.
DELIVERABLES
Our power quality study delivers a data-driven report with recorded measurements, compliance analysis, root cause identification, and specific corrective recommendations including filter sizing and power factor correction specifications.
FAQ
A power quality study measures and analyses the electrical characteristics of your power system including harmonics, voltage variations, transients, and power factor. It identifies disturbances that can damage equipment, disrupt processes, and result in DEWA compliance penalties.
DEWA enforces strict harmonic limits and power factor requirements. Facilities exceeding these limits face penalties and potential disconnection. Additionally, power quality issues cause premature failure of transformers, motors, drives, and electronic equipment, resulting in costly repairs and unplanned downtime.
Our standard power quality study includes a minimum seven-day continuous monitoring period to capture all operating conditions including weekday and weekend patterns, peak and off-peak loads, and any intermittent disturbance events that may not appear during shorter measurement windows.
Carelabs uses professional-grade power quality analysers from Dranetz and Fluke that comply with IEC 61000-4-30 Class A measurement requirements. These instruments capture all power quality parameters simultaneously with high accuracy and time-stamped event recording for detailed analysis.
Yes. A power quality study identifies power factor issues and recommends correction measures that eliminate DEWA reactive power penalties. It also identifies harmonic-related losses in transformers and cables that increase energy consumption beyond what is necessary for your actual productive loads.
Common issues include harmonic distortion from variable frequency drives and UPS systems, low power factor from inductive loads, voltage sags from large motor starting, and neutral overloading from single-phase non-linear loads. These problems are amplified in the UAE due to high cooling loads.
Yes. DEWA applies reactive power charges for facilities with power factor below the required threshold. DEWA also sets harmonic injection limits, and facilities exceeding these limits may face penalties or be required to install harmonic filtering before continued connection to the grid.
A power quality study focuses on electrical disturbances that affect equipment reliability and utility compliance. An energy audit focuses on energy consumption patterns and efficiency opportunities. While related, they address different aspects of facility electrical performance and require different measurement approaches.
Yes. Harmonic distortion overheats transformers, cables, and motors. Voltage sags and transients can trip or damage sensitive electronic equipment, variable frequency drives, and control systems. Chronic power quality issues significantly reduce equipment lifespan and increase maintenance costs.
Cost depends on facility size, number of monitoring locations, and complexity of the electrical system. Carelabs provides customised quotes after reviewing your facility details. The investment typically pays for itself through reduced DEWA penalties, lower energy losses, and prevention of equipment damage.
