System Quality Signal
On this page we show the system quality signal (SQS).
On hourly basis the SQS shows the actual physical quality balance and therewith the use of quality conversion or reverse quality conversion. When the indicator moves from the green zone to one of the orange zones a physical quality problem could occur. Shippers causing this are responsible for regaining the physical quality balance by changing the relation between H and G gas. When the indicator moves into red we will takes action by giving floworders to the parties causing this.
It is possible that the SQS is not shown due to technical failure. In this case, the history file is not updated. The period in which this occurs does not show any value, these cells will be empty.
