Lessons learned: How one power utility averted disaster by executing real-time DGA

Our webinar will showcase how a large hydropower utility in South America, CTM Salto Grande, avoided a catastrophic failure of their GSU by executing real-time dissolved gas analysis (DGA) with a Vaisala OPT100 DGA monitor.

Transformers are a crucial component in power generation, and their failure can lead to a significant loss of generation capacity. Replacing critical assets is often time-consuming and expensive. A catastrophic transformer failure can result in even higher costs due to the longer period of energy loss and possible damage to adjacent assets. This could cost millions in lost revenue.
