Serveron TM3 On-Line Dissolved Gas Monitor

Brand: Qualitrol Company

The TM3 is Serveron®’s highly accurate and repeatable 3 gas online DGA monitor.

Based on an analytical platform built around a Gas Chromatogram (GC) the TM3 takes the recognized laboratory technology onto your transformer and used it to provide you with data capable of employing the globally recognized Duval triangle diagnostic algorithm.

The Serveron® Model TM3 is the only transformer condition alert system in its class that offers legitimate identification of the most critical transformer fault types via Duval’s triangle.
Features
  • Correlates 3 fault gases (acetylene, ethylene, and methane), moisture-in-oil, oil temperature and ambient temperature to transformer load
  • The combination of on-line DGA data automatically populating the Duval Triangle provides unprecedented insight into fault diagnosis
  • Our TM View software allows you to track and alarm on ppm and rate of change for the gases measured while at the same time providing for automatic diagnosis of developing faults using the powerful Duval Triangle algorithm
