CASE STUDY: A stadium solves their unreliable lighting with an EnergyX Portable Power Quality Audit
Customer Challenge
Imagine 60,000 fans walking through stadium entrances, corridors, and cheering on their team from the stands when suddenly, the lights flicker on and off. The field goes dark, play is interrupted, and the stands go silent. This scenario was repeated regularly at a large stadium, causing embarrassment and concern to the stadium and team owners and disappointment to fans. After repeated unsuccessful attempts by electrical contractors to solve the problem, the lighting manufacturer contacted AZZO for assistance.
The Solution
AZZO deployed the EnergyX Portable which sent data to our EnergyX Cloud platform. With data from the EnergyX Portable, our power quality experts detected resonance at the 15th harmonic, which was causing the lights to fail. Due to our expertise with power quality issues, we identified that the resonance was a result of incomplete commissioning of harmonic filters two years earlier. After the harmonic filters were reconfigured, the lights never flickered again.
Customer Benefits
A fan’s focus should always be on the game, not on the grounds in which the game is being played. Thanks to AZZO’s EnergyX Portable, the stadium operations are no longer bigger news than the teams that play there.
AZZO EnergyX Portable
“The stadium harmonics project was challenging from the get-go as we had limited data from the
outset. However, by deploying one of our EnergyX Portable units, we closed this distance. We were
able to achieve a virtual presence through live remote access, empowering us to make informed
decisions which resulted in a constant feed of data every step of the way. Re-tuning the harmonic
filters resulted in stable lighting and mitigated power quality disturbances, ensuring no further
interruptions to the sporting events. Game on!”
