The members of a maintenance team at a Danish power station were fed up getting error messages and false system alarms from one of the boiler’s temperature surveillance systems. The problem occurred when the ambient temperature approached 60˚C. The solution to the problem did not seem straight-forward, but after a talk with a sales engineer they decided to do a test set-up with a isolated TC converter like DRST-FR – and that solved the problem — also at 60˚C.
The power station generates electricity for the Nordic electricity market and supplies heat to more than 85,000 Danish households and industries, including horticultural greenhouses. Today the station is owned by one of Europe’s largest electricity producers.
System errors and false alarms in connection with ambient temperature fluctuations
The station used to get false system alarms and error messages from one of the boilers’ temperature surveillance systems. The problem occurred when the ambient temperature hit 60˚C in the boiler room, which often happened in summer. The team at the power station then agreed to do a TC converter test set-up.
The test set-up delivered stable system monitoring from day one
DRST-FR are designed to operate within a temperature range of -25˚C to 70˚C. To test their ability to solve the problem, 12 DRST-FR were installed in the panel ‑ a cost-efficient solution that delivered stable system monitoring from day one.
