Understanding Power Quality: Essential Steps for Facility Stability

Managing a facility involves more than the simple act of turning things on or off. It requires insight into the underlying quality of the electricity that powers your operations. At Faulkner Haynes & Associates, we know the unseen threats that poor power quality can pose, from raising utility costs to potentially halting production lines. To safeguard your investments and maintain operational continuity, it is vital to delve into the world of power quality.

Decoding Power Quality

The term “power quality” encompasses the consistency and cleanliness of the electricity supplied to your facility. Ideally, this electricity should flow smoothly in a perfect alternating current (AC) sine wave. However, issues occur when there are deviations—commonly known as “dirty power.” These irregularities manifest as sags, swells, surges, and harmonics, all of which can be detrimental to sensitive equipment.

Strategizing Against Harmonics

Harmonics are unwanted components in the electrical system caused by non-linear loads such as computers and Variable Frequency Drives (VFDs). Unlike linear loads that draw current in a smooth manner, these modern devices consume electricity in short bursts, creating distortion in the electrical wave. Over time, unchecked harmonics can lead to excessive heat and energy waste, shortening the lifespan of your facility’s equipment.

To counteract these effects, harmonic mitigation tools like specialized transformers can be deployed. These devices help reduce electrical noise by canceling out harmonic currents before they compromise the broader electrical system. This is crucial for maintaining a stable and efficient operation.

The Necessity of Harmonic Mitigation

Allowing harmonics to persist can severely impact your facility by creating excessive heat, which can damage wires, motors, and transformers. Furthermore, your facility may incur higher energy costs due to inefficient power usage. Implementing harmonic mitigation practices effectively addresses these concerns, enhancing both safety and cost-efficiency.

Managing Surges for Better Power Quality

Surges are brief spikes in voltage that can damage or destroy sensitive equipment. While lightning strikes are a well-known external cause, many surges originate internally from day-to-day operations. Each time heavy machinery or HVAC systems cycle on or off, micro-surges occur, slowly eroding the integrity of your systems.

Surge Suppression: A Necessary Defense

To prevent catastrophic failures, data loss, and cumulative damage from these electrical spikes, surge protective devices (SPDs) are essential. These devices act as safeguards, diverting harmful excess energy away from critical infrastructure. Implementing SPDs at various points within the electrical system provides robust protection against both large-scale and subtle, repeated surges.

Key Actions for Facility Managers

Power quality is a critical aspect of facility management that cannot be ignored. Investing in power quality solutions like harmonic mitigation and surge suppression not only prolongs the lifespan of your equipment but also optimizes energy consumption, reducing overall costs.
