2.2 Secondary Impulse Method
The IRG sends a low
voltage impulse into the
cable under test, it is
reflected positively by the
cable end. Not visible at
this first measurement is
the high resistive fault.
A high voltage impulse
released from the SSG
ignites an arc at fault.
The IRG again sends a
low voltage impulse.
This low voltage impulse
is reflected by the arc at
fault position negative.
