Monitoring Weather Data Critical for Electrical Substation Management

The Imperial Irrigation District in Southern California installed an Orion™ Weather Station at a remote substation that is regularly impacted by wind storms, flash floods, and extreme summer temperatures.

Bethany Villero visited the site on a recent trip and spoke with IID Communications & Control Technician Mizael Huereque, who explained how engineers utilize on-site weather data for critical substation operations. These reasons include:

  • Preparing to supply power from secondary substations to sustain increased load by monitoring high temperatures in the summer months.

  • Anticipating and preparing for fallen trees and power lines by monitoring wind speeds during storms.

  • Adjusting transmission line ratings for efficiency and equipment damage mitigation by factoring temperature, wind speed, and solar radiation data.

School Invests in Weather Station for Hands-On Learning

Image
We are always excited when educators invest in giving their students hands-on knowledge of how weather works, how it’s measured, and how it affects them. South River High School in New Jersey does just that. Last year, the school installed a  Capricorn FLX Weather Station  on one of their buildings. The Climate Change Club uses the data to report hourly weather readings to the National Weather Service. According to their website: “This will make South River High School a weather hub for pilots to collect current weather conditions of our area. The information that the club collects will also be archived for climate change data.” Administrator Kamila Miazio added that the club “provides a weekly forecast, satellite imagery of CONUS, and severe weather updates. The advisor is working to teach students METAR code (the weather code that pilots use to see current weather conditions for the area), report an hourly automatic observation with the weather equipment, record the data and...
