Power quality facts from

the Power Electronics team

Ever seen the TV show Mythbusters? If you're a science buff, it's a must-watch; the team tests the validity of various myths, rumours, movie scenes, and urban legends using scientific methods and experiments. The path to achieving optimal power quality is no different; it's riddled with myths that can lead even the most informed engineers astray.

With that in mind, we've decided to take a leaf out of the Mythbusters playbook and debunk the most common and misleading myths around power quality. So if you're grappling with power quality issues in your electrical systems, download this white paper and learn the truth behind these eight power quality myths:

• Myth #1: The assumption that power correction solves all power quality issues - it's essential to go deeper into power quality management beyond mere power correction to ensure comprehensive solutions and optimal system performance
• Myth #2: Overlooking the impact of non-linear loads - engineers often underestimate the potential of non-linear loads to introduce harmonics and other disturbances
• Myth #3: Ignoring grounding and bonding issues - the consequences of neglecting these critical considerations extend beyond safety concerns
• Myth #4: The assumption that power quality issues only occur externally - it's actually quite rare that power quality disturbances stem from the external power supply
• Myth #5: Thinking power quality is a one-time design consideration - it's actually a dynamic phenomenon that can evolve over time
• Myth #6: Believing power quality is only about the power triangle - neglecting factors such as EMC and RFI can have significant implications
• Myth #7: Not recognising the impact of poor power quality on efficiency - this can result in increased energy consumption, elevated operating costs, and diminished overall system reliability
• Myth #8: A centralised power quality system will solve everything -there’s so much more to it than that

This white paper is aimed at busting these myths, so that you and your team can focus on a comprehensive understanding of power quality. You'll be better placed to address issues proactively, enhance system efficiency, and ensure operational reliability.
