If a ground fault causing a current above the G/F Trip Level but below the S/C Trip Level is already present 

when power is applied, the system trips just as soon as possible, regardless of the G/F Trip Delay setting 
(rationale: the fault may have been present much longer than the delay set time and should be cleared without 
delay). 

3

 The accuracy of the trip point refers to the value of the real world ground fault current (assuming a purely 

sinusoidal wave shape) that just causes a trip when slowly increased from zero. 

4

 The ground fault detection mechanism has a ‘thermal’ behaviour for greatly reduced noise sensitivity: the 

quoted delays are valid for sinusoidal currents exceeding the setpoint by >10 times; for reduced current 
excursions the delay increases as follows: 
 

current = 6 x setpoint: 

add 3 ms 

 

current = 4 x setpoint: 

add 8 ms 

 

current = 2 x setpoint: 

add 20 ms 

 

current = 1.2 x setpoint:   add 60 ms 

For IEC 60755 ‘pulsating DC’ currents, the delay increases by a further 50 ms maximum.
