Actual value of the measured quantity
The actual value of the measured quantity is available locally and remotely. The
measurement is continuous for each measured quantity separately, but the reporting of
the value to the higher levels depends on the selected reporting mode. The following
basic reporting modes are available:
• Cyclic reporting ( Cyclic )
• Magnitude dead-band supervision ( Dead band )
• Integral dead-band supervision ( Int deadband )
Cyclic reporting
The cyclic reporting of measured value is performed according to chosen setting
(
XRepTyp ). The measuring channel reports the value independent of magnitude or
integral dead-band reporting.
In addition to the normal cyclic reporting the IED also report spontaneously when
measured value passes any of the defined threshold limits.
