    Outage events Outage Events When PowerWatch records a sag of below 70Vrms for longer than a second it displays the event as an outage. The VDR will go into self-powered mode (battery) and will sample the voltage every eight seconds. As a result, the shortest outage it will record will be eight seconds.
