When a circuit breaker is used, the VirtualMonitor technology also enables to detect and count trips. A trip is detected if
the 2 following conditions are met:
• the sensor records an opening of the protective device
•
the sensor records an overcurrent ≥ 120% In(*)
(*) It is important to configure the nominal current correctly in the “Loads” configuration menu for the VirtualMonitor
technology to work.
Several protection counters are also accessible thanks to the VirtualMonitor technology:
Protection counter type
Description
Total operation counter
Number of times the protective device was opened
Low-load operation counter
Number of times the protective device was opened when load current was ≤ 5% Inom
On-load operation counter
Number of times the protective device was opened when load current was [5% Inom –
100% Inom)
Overload operation counter
Number of times the protective device was opened when load current was ≥ 100% Inom
Trip Counter
Number of times the protective device has tripped (only available if the protective
device is a breaker)
The VirtualMonitor technology allows to detect several successive openings of a protective device if the interval
between 2 openings is greater than or equal to 200 ms.
Make sure Earth is connected on the DIRIS Digiware U module to use the VirtualMonitor technology.
For the voltage detection (hence the VirtualMonitor technology) to work properly when using iTR current sensors,
make sure the section of live conductors are above the minimal sections given in the table below:
