Delay time
You can use this parameter to set the delay time in order to delay the issuing
of the event message.
Reaction
You can use this parameter to set the behavior of the device if the measured
value is higher than the upper limit (> or >>) or lower than the lower limit (<
or <<). You can select the following options:
Setting Behavior
Off No reaction.
Auto blocking Automatic regulation is blocked.
You can continue to perform tap-change operations in
manual mode.
Auto/manual blocking Automatic regulation is blocked.
You cannot perform tap-change operations in manual
mode.

9.22.3 Power monitoring
For monitoring the transformer's current power, you can set the following
limit values:
Measured value Lower
limit 2 Lower
limit 1 Upper
limit 1 Upper
limit 2
Apparent power S<< S< S> S>>
Active power P<< P< P> P>>
Reactive power Q<< Q< Q> Q>>
Power factor (amount) |cos φ|<< |cos φ|< - -
Table 68: Limit values for power monitoring
You can set the following parameters for each limit value:
▪ Limit value: Absolute limit value
▪ Hysteresis limit value
▪ Delay time limit value
▪ Behavior limit value (only for devices with voltage regulation)
