ABB gas analyser replaces ancestor at underground substation
Process and Control Today, September 2008
The Dinorwig hydroelectric substation in Snowdonia chose an ABB AK100 gas analyser to replace a 30-year-old gas detection system originally supplied by Kent. The system is designed to check for leaks of sulphur hexafluoride (SF6) from high-voltage contactors, where the gas is used as an insulator. Leaks could lead to both suffocation and dangerous arcing in the switchgear.

Measuring Boiler and Furnace Temperatures
By Paul Aloia, Summit Controls
The conventional way of replacing thermocouples in a boiler or furnace requires shutting down the unit—an expensive proposition. Most companies will run with failed thermocouples until it’s time for a normal shutdown, and may suffer inefficiencies and lose their diagnostic capabilities. The solution—using flexible WORM temperature sensors—allows them to replace failed T/Cs from outside the boiler or furnace without shutting down.
