As soon as there is no more free space in the event memory, the oldest val-
ues are overwritten by the new values measured. You can access informa-
tion about the current event memory content via the Info [► 125] menu.
Data recorder
The data-recorder module can be used to save the data listed below and
display and evaluate it either on the display or using the TAPCON®-trol visu-
alization software on a PC.
The following values are displayed:
▪ Measured values
– On-load tap-changer position
– Voltage
– Active current
– Reactive current
▪ Calculated values
– Active power
– Reactive power
– Apparent power
– Output factor
Calculation of the values stated depends on the measured values captured
and the parameters set, for example:
▪ Current measuring circuit
▪ Primary current
▪ Voltage transformer data from primary and secondary sides
A correct calculation can only be undertaken if you have correctly entered
the configuration data in full.
Setting undervoltage threshold
You can use these parameters to set the undervoltage threshold as a rela-
tive or absolute value. If the voltage falls below the set undervoltage thresh-
old, high-resolution measured values are saved for as long as this situation
prevails.
