1.5.2 

Tripping mode - selection of single or three phase tripping 

This selects whether instantaneous trips are permitted as Single pole, or will always be 3 
pole.  Protection elements considered as “instantaneous” are those normally set to trip with 
no intentional time delay, i.e.: Differential, directional earth/ground DEF aided scheme and if 
fitted, Zone 1 distance and distance channel aided scheme.  The selection 

1 and 3 pole

 

allows single pole tripping for single phase to ground faults.  The selection 

3 pole

 converts 

all trip outputs to close Trip A, Trip B and Trip C contacts simultaneously, for three pole 
tripping applications. 

In the case of the P544/P546, the tripping mode can be set independently for the two circuit 
breakers controlled. 

Logic is provided to convert any double phase fault, or any evolving fault during a single pole 
auto-reclose cycle into a three phase trip.  Two phase tripping is never permitted.  This 
functionality is shown in Figure 12 for P543/P545 and in AR Figure 63 (logic diagram 
supplement) for P544/P546 models.

1.5.3 

Pole dead logic 

Pole dead logic is used by the relay to determine when the circuit breaker poles are open 
(“pole dead”).  This indication may be forced, by means of status indication from CB auxiliary 
contacts (52a or 52b), or internally determined by the relay.  When no auxiliary contacts are 
available, the relay uses lack of phase current (Setting: CB FAIL & I</UNDER CURRENT/I< 
Current Set),

 

and an undervoltage level detector (pick up fixed at 38.1 V - drop off fixed at 

43.8 V

 

to declare a “pole dead”.   

Note:

  

If the VT is connected at the busbar side, auxiliary contacts (52a or 
52b) must be connected to the relay for a correct pole dead indication.  
The logic diagrams, Figure 13 and Figure 14 below show the details:
