Doble Engineering & Maschinenfabrik to Enhance Online Monitoring for Gas Analysis

Source: 12/14/2023, Location: North America

Doble Engineering, a leader in power grid diagnostic solutions, today announced its collaboration with Maschinenfabrik Reinhausen GmbH (MR), a leader in global energy technology. Through the collaboration, MR will act as a re-seller of Doble's Calisto® R9 Dissolved Gas Analysis (DGA) monitor, providing early fault detection and lifetime-accurate DGA diagnostics to more asset managers worldwide. The collaboration also enables customers to purchase MR's holistic transformer control, regulation and monitoring system ETOS® and the Calisto R9 as an integrated system.

An industry-first, U.S.-patented system that uses water vapor as a calibrant, allows the Calisto R9 to deliver accurate gas readings over the long haul without the maintenance costs associated with cylinders of consumable gas. ETOS enables users to analyze, evaluate and record all relevant operating data of their power transformers based on the function Asset Intelligence. Beyond the broad sensor portfolio from MR, ETOS can also include sensors from other manufacturers and combine all the signals in a centralized, intelligent edge system. The integration of the Calisto R9 and ETOS is a logical next step, bringing two groundbreaking products together.

"The growing demand for digitization and monitoring of power transformers increases the number of ETOS systems worldwide and at the same time, the request from our customers for a wide solution range. Doble shares our commitment to providing utility teams with intelligent systems for a safe, economical and resilient power supply, making this collaboration a natural fit," said Roland Götz, Head of Innovation and Technology Automation at Maschinenfabrik Reinhausen (MR).

"Nowadays, creating synergies between partners is important in order to offer operators and manufacturers the best possible support and non-proprietary interfacing to meet the challenges of the energy transition," continues Wilfried Breuer, Managing Director at Maschinenfabrik Reinhausen (MR).

Calisto R9 reports hourly readings of all the key transformer fault gases. A new differential infrared photoacoustic spectroscopy (DIPAS) method provides accurate measurements of carbon monoxide (CO), carbon dioxide (CO2), methane (CH4), acetylene (C2H2), ethylene (C2H4) and ethane (C2H6). Hydrogen (H2) is measured using the sensitive and stable thermal-conductivity method that has been a differentiator for Calisto fault-detection monitors for more than 20 years.

"We are very proud that a century of knowledge in asset health and maintenance and deep experience in dissolved gas analysis made it possible to create a next-generation product that simplifies dissolved gas monitoring for utilities globally," said May Scally, Chief Operating Officer at Morgan Schaffer, a Doble company since 2017. "We look forward to being able to expand the reach of the Calisto R9 with MR and its pioneering monitoring system ETOS by offering it to more asset management teams worldwide."

"We're thrilled to collaborate with an established, trusted, leader in the space, whose products regulate 50% of the electricity produced worldwide, enabling us to expand our growing global footprint," added Matthew Carrara, President of Doble. "Together, we'll equip more asset management teams with the ability to identify and detect faults early through DGA and ultimately safeguard asset health and grid reliability."

Calisto R9 is produced at Doble's Morgan Schaffer facility in Montréal, Québec, Canada using world-class methodologies for lean-manufacturing and quality assurance. After-sales support and dedicated customer care will be available through certified MR representatives as well as Doble's international network of channel partners and affiliated companies.
