No more false alarms
10 August 2016
"Approximately 50 percent of power transformer faults can be detected with the right online monitoring tools, meaning that severe failures can be prevented. But nobody wants monitors that give false alarms or require regular maintenance. So we created a product that does not," explains Vaisala Controlled Environment product manager Juhani Lehto.
The Vaisala Optimus(TM) DGA Monitor for Transformers carries an IR sensor based on Vaisala core measurement technology and components manufactured in their in-house cleanroom. It uses vacuum gas extraction, which gives a fully representative sample and means no data fluctuation due to oil temperature, pressure, or type. Hermetically sealed and protected optics prevent sensor contamination, and long-term drift is eliminated with an autocalibration functionality.
