Reading Measured Values and Metered Values
8.6.2
You can read measured and metered values on the device display or with DIGSI 5. You can find these values in
the respective function groups such as the Line function group. Take note that the scope of measured values
is determined by the type and number of assigned measuring points. If only one measuring point, for example
3-phase current, is assigned to the function group, then all measured values linked to the voltage (voltage,
power, energy) are omitted. These measured values are hidden automatically.
In the following, you will find an example how to reach the individual measured or metered values.
Reading Measured Values on the Device
You can read the measured values in the function group Line 1 as follows:
•
In the main menu of the device display, switch to
Main menu → Measured values → Line 1
The following measured-value group is displayed for you, and you can find the available measured and
metered values in
–
Operational measured values
–
Fundamental component/symmetrical components
–
Functional measured values (protection-specific measured values)
–
Minimum/maximum/mean values
–
Energy
–
User-defined measured values

C53000-G5040-C003-9, Edition 06.2018
Description
These metered values are determined for active and reactive energy. Restore
time, restore interval and counting mode are adjustable. Restoration can be
initiated via a binary input.
The following metered values are available:
•
Active energy Wp+ (export), Wp- (import)
•
Reactive energy Wq+ (export), Wq- (import)
The following statistical values are formed:
•
Number of initiated switching operations of the circuit breaker (opera-
tion counter); the contactor trips and switch actuations by the control
are counted.
•
Number of initiated switching operations of the circuit breaker, sepa-
rated by circuit-breaker pole
•
Sum of total primary breaking currents
•
Sum of the primary breaking currents, separately for each breaker pole
These metered values can be determined for any metered amounts received
via a binary input.
•
The unit and significance of a pulse, restore time, restore interval, and
meter mode can be set.
•
Restoration can be initiated via a binary input
