Innovations and Best Practices for Temperature Monitoring in Hydropower Stations

Jul 18, 2024
Operations and Maintenance

This presentation delves into best practices and recent innovations in temperature measurement technology from a field installation/operations perspective. A vast majority of the temperature measurement applications in a hydropower station tend to be on rotating equipment (pumps, compressors, turbines, generators). Field installations for temperature instruments (mechanical and electronic) can have various levels of complexity depending on the application. Beyond installation of the instrument, there are nuances to configuration of the device that can help improve performance characteristics. Factors relating to potential causes of failure as well as possible steps to mitigate and/or improve instrument life are discussed.

The presentation derives most of its data based on findings and experience gained from the hundreds of field instrument surveys at hydropower stations across North America. The most common causes of failure for temperature instruments in a hydropower station and potential steps that can be taken to mitigate some of the causes of failure are discussed. Calibration approach for temperature elements is also reviewed to ensure longevity and reliability.
