Power quality problems can interfere with equipment performance and create conditions that lead to unplanned downtime. The quality of the power delivered throughout a facility directly affects how motors, drives, controls and other connected equipment operate under load.

Undetected electrical disturbances can cause ongoing performance problems that are difficult to diagnose without detailed testing and system evaluation. Our power quality analysis services identify the source of electrical disturbances, enabling facilities to correct issues before they affect production or damage critical systems. Identifying these issues early helps facilities protect equipment and maintain consistent, reliable electrical operation.

Power Quality Monitoring and Data Collection

Using power quality monitoring systems, we evaluate how electrical systems perform over time and under varying load conditions. Monitoring equipment records electrical activity continuously, allowing technicians to capture disturbances that may occur during peak demand or changing operating conditions.

The monitoring process may help identify:

• Voltage fluctuations

• Harmonic distortion

• Transient electrical disturbances

• Ground-related issues

• Irregular system behavior under load

By monitoring and regularly reviewing operating data, technicians can determine whether disturbances originate from internal equipment, facility distribution conditions or incoming utility power sources.

Harmonic Distortion Evaluation

Nonlinear electrical loads can distort voltage and current waveforms throughout a distribution system. When harmonic currents circulate through the electrical system, they can increase heat in transformers and conductors, potentially leading to damage or fluctuating power quality.

Facilities that rely on drives and automation systems are more susceptible to harmonic distortion. Power Solutions Group offers harmonic analysis services to help determine whether harmonic conditions are affecting electrical system performance or contributing to equipment stress. Evaluating harmonic levels helps determine whether mitigation strategies or system adjustments are necessary to maintain reliable operation.

Our technicians use advanced power quality monitoring equipment that records voltage and current waveforms under regular operating conditions. The recorded data is then evaluated using Fast Fourier Transform (FFT) software and compared against acceptable limits such as IEEE Standard 519, which defines allowable distortion levels in electrical power systems.

Power Factor Correction

Electrical system efficiency can also be affected by reactive power demand. Reviewing opportunities for power factor correction helps technicians see whether electrical infrastructure is operating efficiently under load.

Low power factor conditions affect electrical systems in several ways, such as:

• Increased current required to deliver usable power

• Higher electrical losses within the distribution system

• Additional demand placed on transformers and conductors

• Reduced available capacity within the electrical infrastructure

Industrial Power Quality Study

An industrial power quality study provides a comprehensive evaluation of how electrical conditions affect equipment operation and system reliability. During this process, our technicians gather system data and evaluate how disturbances interact with facility loads.

A study may include:

• A review of disturbance patterns

• A load-related performance evaluation

• Analysis of harmonic conditions

• Assessments of transient events

• Identification of potential mitigation needs

Power quality issues are often interconnected. A structured evaluation process identifies the root cause of electrical issues, enabling facilities to take targeted corrective action and maintain reliable system performance.
