Overview
The content of this lecture is training
on
indication
and
location of
DC ground faults in a normally ungrounded
DC multi-feeder
distribution system.
The lecture
is design to provide the basic skills in
troubleshooting
DC ground faults with the GFAL-A/B
Method and Instrument
Includes theory of operation
on the different types of
commercially
available DC ground fault indicator and
locator
instruments, their advantage and disadvantage.
