DGA, Oxygen and Total Gas Pressure: getting the best measurements for protecting your power transformer

Substation at night
Power Generation and Transmission

How to detect if your power transformer is leaking ambient air in? That's the big question in today's DGA webinar. 

In this webinar, Vaisala's Senja Leivo will discuss the methods and means of detecting oxygen ingress reliably, and outline an improved method – a best of both worlds – combining Total Gas Pressure (TGP) and direct O2 measurement. 

 

Key takeaways:

  • Oxygen & power transformers – where does it come from and why does it matter?
  • Methods of detecting oxygen ingress and their merits
  • Is detecting active oxidation processes possible?
  • Total Gas Pressure & direct O2 measurement – how to get the best of both worlds
  • Quick look at what the OPT100 online DGA monitor brings to the table
  • Q&A session
