Dependable Data, no False Alarms
"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," said Product Manager Juhani Lehto at Vaisala Controlled Environment.
The Vaisala Optimus DGA Monitor for Transformers does not give false alarms. It carries an IR sensor based on Vaisala core measurement technology and components manufactured in an 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 a unique autocalibration functionality.
Installation in Less than Two Hours
The Vaisala Optimus DGA Monitor is designed to be installed in less than two hours - just by connecting the oil, power and communications. Browser-based user interface brings ease of use, as no additional software is needed. In case of a disturbance such as power outage, self-diagnostics enables automatic recovery.
The product withstands harsh conditions. The Optimus has a robust construction with stainless steel pipes and temperature controlled housing, and it is rated IP66. The hermetically sealed structure tolerates vacuum and pressure variation, and its magnetic pump and valves mean superb performance and durability in any environmental conditions. There are also no consumables to service or replace.
