Measured input

The function block uses analog current measurement values and always uses calculated positive and

negative sequence currents. In the broken conductor mode (I2/I1) the function also uses the RMS

values of all phase currents to check the minimum current. Zero sequence and component sequence

angles are used for fault registering and for fault analysis processing. A -20 ms averaged value of the

selected magnitude is used for pre-fault data registering.

General settings

The following general settings define the general behavior of the function. These settings are static i.e.

it is not possible to change them by editing the setting group.

are supervised or whether only the negative sequence is used in detecting

unbalance.

Pick-up

The setting parameters

set

and I2/I1

set

control the the pick-up of the I2> function. They define the

maximum allowed measured negative sequence current or the negative/positive sequence current ratio

before action from the function. The function constantly calculates the ratio between the

set

and the

measured magnitude (

). The reset ratio of 97 % is built into the function and is always relative to the

xset

value. The reset ratio is the same for both modes.
