Use the disturbance report to provide the network operator with proper information
about disturbances in the primary network. Continuous collection of system data and,
at occurrence of a fault, storing of a certain amount of pre-fault, fault and post-fault da-
ta, contributes to the highest possible quality of electrical supply. The stored data can
be used for analysis and decision making to find and eliminate possible system and
equipment weaknesses.
The function comprises several sub functions enabling different users to access relevant
information in a structured way.

The disturbance report is a common name for several facilities to supply the operator
with more information about the disturbances in the system. Some of the facilities are
basic and some are optional in the different products. For some products not all facilities
are available.
The facilities included in the disturbance report are:
•
General disturbance information
•
Indications
•
Event recorder
•
Fault locator
•
Trip values (phase values)
•
Disturbance recorder
The whole disturbance report can contain information for up to 10 disturbances, each
with the data coming from all the parts mentioned above, depending on the options in-
stalled. All information in the disturbance report is stored in non-volatile flash memo-
ries. This implies that no information is lost in case of loss-of-power supply
