Protection against minimum frequency (function UF)
This protection intervenes by generating an alarm or making the circuit-breaker
open after the adjusted time-delay (t9) when the frequency varies below the
set threshold f12.
It is used above all for installations supplied by generators and co-generation
plants.
Protection against maximum frequency (function OF)
This protection intervenes by generating an alarm or making the circuit-breaker
open after the adjusted time-delay (t10) when the frequency exceeds the set
threshold f13.
It is used above all for installations supplied by generators and co-generation
plants.
Protection against overtemperature (function OT)
This protection allows signaling of the presence of anomalous temperatures
which might cause malfunctioning of the electronic components of the trip
unit.
If the temperature reaches the first threshold, (70°C), the trip unit shall advise
the operator through the lightening up of the “warning” led; should the temperature reach the second threshold (85°C), besides the lightening up of the
“warning” and “alarm” leds, the circuit-breaker would be tripped (by enabling
the proper parameter).
Overload protection with curves according to IEC60255-3
This protection function against overload finds its application in the co-ordination
with MV releases and fuses.
In fact it is possible to obtain a co-ordination among the tripping curves of
the circuit-breakers by getting nearer to the slopes of the tripping curves of
MV releases or fuses, so that time-current selectivity between LV and MV is
obtained. Besides being defined by a current threshold I1 and by a trip time
t1, the curves according to Std. IEC 60255 are defined by the parameters “K”
and “a” which determine their slope
