Trip Blocking and Time Delay Disable 

Trip Blocking

 inputs can be programmed into Time and Instantaneous Overcurrent elements, 

which disable element trip if input is activated before trip is generated. If input is activated after 
tripping, trip is reset. Trip blocking inputs must be programmed before this blocking logic can be 
used. 
 
Another  programmable  input  exists  that  can  turn  a  given  Time  Overcurrent  element  into 
instantaneous. Said input is called 

Timer Disable

 and is available for all time-delayed elements. 

6.2 

Breaker Failure 

The Breaker Failure function is designed to detect the failure of a circuit breakers response to 
trip  commands  from  protection  elements.  It  also  generates  a  trip  signal  to  open  adjacent 
breakers  capable  of  isolating  the  fault.  The  operation  of  this  function  is  shown  in  the  block 
diagram of the following figure. 
 
The 

Breaker  Failure  Initiate

  signal 

(

I_FI

)  is  activated  through  a  Trip 

Command  generated  by  the  terminal 
unit  Internal  Protection  elements 
(

DISP

)  or  an  External  Protection  Trip 

input  (

APE

).  Once  the 

I_FI

  signal  is 

activated  and  current  is  still  detected 
by  the  terminal  unit  (

P_INT

  signal), 

the 

Breaker  Failure

  signal  (

P_FI

starts  the  counter  for  the 

Breaker 

Failure  Time  Delay

  (

T_FI

).  If 

T_FI

 

times  out  before  either 

I_FI 

resets, 

indicating  that  the  conditions  which 
initiated Breaker Failure are no longer 
present,  or 

P_INT

  resets,  indicating 

that there is no current  detected  by 
the terminal unit, the 

Breaker Failure 

Output

 (

FI

) is activated. 

Figure 6.6 

Breaker Failure Element Block Diagram. 

 
 
The reset of either the 

I_FI

 or 

P_INT

 signal causes the 

T_FI

 timer to reset and stop the Breaker 

Failure process. 
 
The 

P_INT

 signal, which indicates the presence of current, is active whenever any of the units 

pickup  levels  are  exceeded.  These  fast  reset  current  level  detectors  are  intended  to  stop  the 
timer as soon as the breaker is open and current has disappeared to insure that the 

FI

 signal is 

not triggered inadvertently. 
 
In order to activate the breaker failure element from an external protection trip input, one of the 
terminal unit Status Contact Inputs must be configured as an 

External Protection Trip Input

 

(

APE

).  If  an  input  is  not  assigned  as  an 

External  Protection  Trip  Input

,  the 

APE

  signal  will 

default to a logic “0”. 
 
Additionally,  one  or  more  of  the  Auxiliary  Contact  Outputs  must  be  configured  as  a 

Breaker 

Failure Output

 (

FI

) to produce a contact output for initiating backup tripping.
