Inrush Restraint

When applying the protection device to transformers where high inrush currents are to be expected, the 7SJ61 
can make use of an inrush restraint function for the overcurrent elements 50-1, 51, 50N-1 and 51N as well as 
the non-directional overcurrent elements.

Inrush restraint is only effective and accessible if address 

122

 

InrushRestraint

 was set to 

Enabled

. If this 

function is not required, then 

Disabled

 is set. In address 

2201

, 

INRUSH REST.

 the function is switched 

ON

 

or 

OFF

 jointly for the overcurrent elements .

50-1 PICKUP

,

51 PICKUP

, 

50N-1 PICKUP

 and 

51N PICKUP

The inrush restraint is based on the evaluation of the 2nd harmonic present in the inrush current. Upon delivery 
from the factory, a ratio 

I

2f

/

I

f

 of 15 % is set. Under normal circumstances, this setting will not need to be 

changed. The setting value is identical for all phases and ground. However, the component required for re-
straint may be adjusted to system conditions in address 

2202

 

2nd HARMONIC

. To provide more restraint in 

exceptional cases, where energizing conditions are particularly unfavorable, a smaller value can be set in the 
aforementioned address, e.g. 12 %. Irrespective of parameter 

2202

 

2nd HARMONIC

, rush blocking will only 

occur if the absolute value of the 2nd harmonic is at least 0.025 * I

Nom,sec

.

The effective duration of the cross-blocking 

2203

 

CROSS BLK TIMER

 can be set to a value between 0 s (har-

monic restraint active for each phase individually) and a maximum of 180 s (harmonic restraint of a phase 
blocks also the other phases for the specified duration).

If the current exceeds the value set in address 

2205

 

I Max

, no further restraint will take place for the 2nd har-

monic.

Manual Close Mode (phases,ground)

When a circuit breaker is closed onto a faulted line, a high-speed trip by the circuit breaker is usually desired. 
For overcurrent or high-set element the delay may be bypassed via a Manual Close pulse, thus resulting in 
instantaneous tripping. This pulse is prolonged by at least 300 ms. To enable the device to react properly on 
occurrence of a fault in the phase elements, address 

1213

 

MANUAL CLOSE

 has to be set accordingly. Corre-

spondingly, address 

1313

 

MANUAL CLOSE

 is considered for the ground path address. Thus, the user deter-

mines for both elements, the phase and the ground element, what pickup value is active with what delay when 
the circuit breaker is closed manually.
