Power Quality

Power interruptions, voltage sags or surges, harmonic distortion and other power quality problems can disrupt your facility operation and can even damage equipment. We can help you address these challenges with a comprehensive array of products and consulting/diagnostic services.

Even brief power fluctuations can result in lost production, higher operating costs, lower product quality, lost business, safety hazards and environmental releases. One momentary power disruption could shut down an entire manufacturing process, endanger a hospital’s patient care or crash a data processing system and keep it down for hours.

When we investigate a power quality problem, we start by thoroughly understanding the problem. This is accomplished by conducting a site investigation or by interviewing facility personnel. Often we will install monitoring instruments to capture electrical anomalies. When we identify the root cause of the problem, we recommend a cost-effective solution. Examples of services we provide are:

PQ Services

• Equipment sensitivity and nuisance shut down assessment
• Temporary power monitoring
• Continuous power monitoring with internet access
• Power Factor analysis
• Voltage regulation and unbalance assessment
• Wiring and grounding assessment
• Transient fault analysis
• Harmonic analysis
• Assessment of electric utility service performance
• Assessment of manufacturer’s equipment deficiencies
• Education and training seminars with Continuing Education Unit credits

We use a variety of high quality suppliers to apply state of the art, cost effective solutions. Often our cost is minimal, such as merely configuring equipment to take advantage of existing equipment capabilities. When other solutions are required, typical power conditioners that we commonly use include:

PQ Conditioners

• Uninterruptible power supplies
• Constant voltage regulators and line conditioners
• Isolation transformers
• Harmonic filters
• Transient voltage surge protectors
• Power Factor correction equipment
• Emergency generators
• Solid state switches
• Line reactors

PQ Monitoring

We can provide a continuous power monitoring system. Information can be made available to you in several forms (e.g. at the load center, personal computer, or through the internet and by personal pager). We can provide systems that enable our customers to quantify any power quality event that occurred at the facility. Also, data is stored historically, enabling large volumes of data to be presented in easily-understood formats.

We match the power quality problem with an optimized solution based on the work scope desired by you. This scope can include design, project management, mitigation equipment, installation, startup, and including a turnkey project. There is no risk or cost to explore what we can do to solve your facility’s power quality problem.
