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.

The pick-up activation of the function is not directly equal to the START signal generation of the

function. The START signal is allowed if the blocking condition is not active.

Read-only parameters

The relay's

Info page displays useful, real-time information on the state of the protection function. It is

accessed either through the relay's HMI display, or through the setting tool software when it is

connected to the relay and its Live Edit mode is active.

Displays the status of the protection function.

Function blocking

The block signal is checked in the beginning of each program cycle. The blocking signal is received

from the blocking matrix in the function's dedicated input. If the blocking signal is not activated when

the pick-up element activates, a START signal is generated and the function proceeds to the time

characteristics calculation.

If the blocking signal is active when the pick-up element activates, a BLOCKED signal is generated and

the function does not process the situation further. If the START function has been activated before the

blocking signal, it resets and processes the release time characteristics similarly to when the pick-up

signal is reset.

The blocking of the function causes an HMI display event and a time-stamped blocking event with

information of the startup current values and its fault type to be issued.

The blocking signal can also be tested in the commissioning phase by a software switch signal when

the relay's testing mode "Enable stage forcing" is activated (

General

→

Device).

The variables the user can set are binary signals from the system. The blocking signal needs to reach

the device minimum of 5 ms before the set operating delay has passed in order for the blocking to

activate in time.
