Fundamentals Of
Differential Protection
Differential Protection
Used where:
Protection co-ordination is difficult / not
possible using time delayed elements
Fast fault clearance is critical
Can be used on all items of plant in one form or
another (i.e. Generators, transformers, lines, cables,
busbars, motors) to form a defined zone of
protection dictated by current transformer location.
