Monitoring the instantaneous or half-wave values
You can enable the following functions:
● Voltage swell (Page 116)
● Voltage dip (Page 118)
● Voltage peaks (Page 121)
● Current peak value (Page 127)
● Overcurrent value (Page 129)
The results are mapped in the phase-specific data records DS 147 (Page 248), DS 148
(Page 251) and DS 149 (Page 254) and in the power quality analysis data record DS 160
(Page 259).
In addition, you can incorporate the results using IDs in the measured value data record of
the user-defined data record DS 151 (Page 258) and in the user data variants 1/2.
You can monitor the results for limits (Page 77) and generate hardware interrupts.
