Event Analysis
CRSTT Use Case

We have observed significant sustained voltage oscillations on the ATC transmission system that were not visible in our SCADA data. These oscillations are normally in the 0.6 – 0.75 Hz range and are lightly damped. They can persist for weeks and then disappear for weeks and even months.
