TVS T1 ~250 400 V
Filtering
The analog signal capture portion of the IC includes a
single pole filter that can be set externally with Cidf. This
provides an additional layer of protection against false
tripping under steady state noise conditions. High frequency
steady state noise is common with pumps, motors or other
cyclic noise generators.
Cidf = 220 nF = 1 KHz low pass.
Setting Trip Sensitivity
The CTresD resistor sets the threshold for the differential
current fault levels. Increasing CTresD causes the fault
levels to trip at lower differential currents. CT efficiency at
60 Hz must be considered.
. CTresD= 400*#Turns – Subject to CT efficiency at 60 Hz
