Vaisala DGA Monitors for Transformers

Dissolved gas analysis (DGA) is a critical component in preventing power transformer failure. Dissolved gas levels in transformer oil can indicate the existence of a fault and the rate of change in these levels can be used to determine its severity.

By giving you accurate, real-time trend data without false alarms, Vaisala DGA monitoring helps you spot problems early on. Vaisala DGA monitors simplify decision-making about when to service, upgrade, or refurbish your power transformers.​​
