Reading Measured Values and Metered Values

8.5.2
You can read measured and metered values on the device display or with DIGSI 5. You 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.
It is then explained later by example how you reach the individual measured values.

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
