Event logging
Description
The event logging function allows the user to log each significant measured item (see list here below) since last clear-
ance:
– the maximum (or minimum) value
– the duration above (or below) the threshold.
Once a threshold has been set (see example below), the RVT starts recording the maximum (or minimum) value auto-
matically as well as the total duration until it is reset.
Threshold
Recorded values
The event logging function allows the user to record the time during which a measured value exceeds a threshold and
its maximum value for the following parameters : Vrms [V], Irms [A], P [kW], Q [kvar], S [kVA], THDV [%], THDI [%],
missing Q [kvar], frequency* [Hz], T1* [°C or °F] to T8* [°C or °F].
* Minimum values and duration below a threshold are also recorded for the frequency and the temperatures.
Example
Recording of information on Vrms. Voltage network: 400V.
STATUS
Approved
Total duration = t1 + t2 + t3
