Total Gas Pressure
Maximize your power transformer's operational life
Total gas pressure, or TGP, is a groundbreaking method for detecting air leaks into your transformer. Robust, reliable & intuitive, it helps maximize your power transformer's operational life. And the best part is that it comes as standard in the Vaisala Optimus™️ OPT100 online DGA monitor.
Robust, intuitive & reliable answer to air leaks
Transformers are sealed to keep ambient air and its oxygen from leaking in. Oxygen will prematurely age and weaken the paper in your transformer's windings, potentially shortening your transformer's operational life by years.
Total gas pressure is the answer to maximizing your transformer's operational life.
Measuring oxygen directly is not needed
While it seems like the obvious answer, using online oxygen measurement to detect air leaks is anything but simple.
If you have an oxygen-consuming reaction inside your transformer, a direct oxygen reading may look low and lead you to think your transformer is sealed. In reality, you could have both an air leak and a reaction that consumes the oxygen.
