The following short descriptions are entered within the Email text (see address list):
<ul1min>
=
Minimum value of voltage in phase L1.
<ul2min>
=
Minimum value of voltage in phase L2.
<ul2min>
=
Minimum value of voltage in phase L3.
<tsu1minon_s> + <tsu1minon_m> = Start of short interruption in UTC time (S Milliseconds).
<tsu1minoff_s> + <tsu1minoff_m> = End of short interruption in UTC time (S Milliseconds).
The short interruptions are set to the actual values while creating the email. The minimum values have the average of
10 periods. More exact data are saved in the trigger memory (True RMS values over 128 periods) and can be read with
PSWbasic/professional. If the clock of the UMG507E/EP is synchronized by a NTP Server, the accuracy of the time
is about10 to 20ms. Three emails are required.
