2.4.2.

Current protection function dependencies

The current based protection functions are relative to I

mode

which is dependent of the application mode. In the motor

protection mode all of the current based functions are relative
to I

mot

and in the feeder protection mode to I

with following

exceptions.
I

> (46), I

>> (47), I

> (48), N> (66) are always dependent on

mot

and they are only available when application mode is in the

motor protection.

2.5.

Overcurrent protection I> (50/51)

Overcurrent protection is used against short circuit faults and

heavy overloads.
The overcurrent function measures the fundamental frequency

component of the phase currents. The protection is sensitive for

the highest of the three phase currents. Whenever this value
exceeds the user's pick-up setting of a particular stage, this

stage picks up and a start signal is issued. If the fault situation
remains on longer than the user's operation delay setting, a

trip signal is issued.

Three independent stages

There are three separately adjustable overcurrent stages: I>,

I>> and I>>>. The first stage I> can be configured for definite
time (DT) or inverse time operation characteristic (IDMT). The

stages I>> and I>>> have definite time operation
characteristic. By using the definite delay type and setting the

delay to its minimum, an instantaneous (ANSI 50) operation is

obtained.
Figure 2.5-1 shows a functional block diagram of the I>

overcurrent stage with definite time and inverse time operation
time. Figure 2.5-2 shows a functional block diagram of the I>>

and I>>> overcurrent stages with definite time operation delay.

Inverse operation time

Inverse delay means that the operation time depends on the

amount the measured current exceeds the pick-up setting. The
bigger the fault current is the faster will be the operation.

Accomplished inverse delays are available for the I> stage. The

inverse delay types are described in chapter 2.23. The device
will show the currently used inverse delay curve graph on the

local panel display.
