To help supply all of Air Products Group’s power needs, Zigor equipped the plant with a medium voltage transformer
(PRWEB UK) 28 February 2013
Global uninterruptible power supply supplier Zigor is delighted to announce details of how it met the power requirements of a hydrogen production plant in Catalonia, Spain.
The factory, owned by Air Products Group – a worldwide supplier of industrial gases and equipment – supplies one of the most important oil refineries in Spain with hydrogen 365 days of the year.
The plant, based in Tarragona, is directly powered by a transport line but they were still suffering voltage dips of up to 50 per cent due to the heavy-duty motors at the refinery as well as occasional summer storms.
The motors work at medium voltage (6.6 kV) and their systems are sensitive to sags when the voltage drops below 12-15 per cent and are stopped for security reasons as hydrogen is highly explosive. The supply of hydrogen to the refinery would also be stopped causing high downtime financial losses as it takes three full days to restart the entire refining process.
To help solve this problem and supply all of Air Products Group’s power needs, Zigor equipped the plant, which has two feeders, with a medium voltage transformer of 2.1 MW 6.6 kV and included medium voltage motors at 6.6 kV to protect the hydrogen generation process.
Zigor also installed a medium voltage SET DVR of 2.4 MW nominal power which provide a stable voltage of 6.6kV (± 1%) even if voltage dips drop the 40 per cent of nominal voltage value. Now Zigor’s DVR continuously protects the whole plant (excluding non-critical services) for the production process against emergency stops due to voltage dips.
