PRODUCT SPECIFICATION
RV4140A
3
The value of R
SET
to meet nominal ground fault tip current
specification is:
Where:
R
SET
is in k
W
T is the time delay in ms
P is the period of the line frequency in ms
I
FAULT
is the desired ground fault trip current in mA
RMS.
N is the number of sense transformer secondary turns.
This formula assumes an ideal sense transformer is used.
The calculated value of R
SET
may have to be changed up to
30% when using a non-ideal transformer.
