Houston Hobby Airport
OVERVIEW
An existing solar photovoltaic system installed at Hobby Airport in Houston, TX was frequently going offline due to voltage spikes from the grid power. An active method was unavailable onsite to identify when the spikes occurred and under what conditions. Claraxio was installed and integrated into the Schneider Electric power meter connected to the switchgear at the site. Since the switchgear is located in a remote basement without internet access, a live data stream was established using a cellular network to monitor the voltage passing through the power meter. The reported data helped to pinpoint voltage spikes and hold the utility provider accountable for not providing the rated voltage.
IMPACT
- Robust implementation to support any shortcomings of operational data.
- Use isolated data transmission using a cellular network for remote sites.
- Uninterrupted data transmission and monitoring.
METRICS
- 13 points trending at one second interval to identify voltage spikes.
- Six voltage spike incidents have been identified and reported to the utility provider thus far.
