Megger
Murray loop
test
Electro-dynamometer
Ohm-meter
Murray loop
test
Murray loop
test or Blavier test or Varley loop test or fisher loop test- This test is used
to find 1 fault location in an underground cable by making wheatstone bridge in
it and by comparing the resistance we shall find out the fault location.
