DCH Techology, Inc. Sensor Successfully Used in Transformers
|An SI Board Since February 1998|
SHERMAN OAKS, Calif., Feb. 17 /PRNewswire/ -- DCH Technology, Inc. (OTC Bulletin Board: DCHT - news) a Sherman Oaks, California based manufacturer of new generation hydrogen monitoring equipment, announced the successful testing of the Robust Hydrogen Sensor in transformer oil.
Power distribution transformers, which can be seen on power poles across the country, are typically cooled with mineral oil. During operation, hydrogen gas is naturally generated inside the transformer. When transformers begin to function abnormally, the rate of hydrogen gas production increases.
A FORTUNE 100 manufacturer of power distribution transformers has purchased DCH sensors to monitor the amount of hydrogen gas produced by their equipment. The sensors provided by DCH were placed into the transformer oil which was heated to 100 degrees C (212 degrees F) to reflect a typical internal operating temperature. Conventional hydrogen gas sensors cannot operate reliably in these harsh conditions.
The DCH sensors, however, operated exceptionally well. Plans are now being made to expand the qualification of DCH sensors for broad installations. This could lead to the specification of DCH sensors on new transformers as well as retrofits to equip transformers already in use around the world. Transformers equipped with DCH hydrogen sensors will operate safely for longer periods.
DCH Technology is a sensors and safety engineering firm which has developed its hydrogen sensor for use in manufacturing, aerospace applications (including a NASA Space Shuttle flight in October 1998), industrial gas production and storage, fuel cell technologies (for automotive and energy generation uses), and other hydrogen-related applications.
