Filed: 1952-03-04
Abstract: 725,141. Testing for earth faults. APPS, R. E. March 3, 1953 [March 4, 1952], No. 5699/52. Class 37. [Also in Group XXXVII] Apparatus for indicating the existence of an earth fault on a laid cable comprises a magnetic circuit with an air-gap in proximity to which is mounted an armature C, the unbalance current which flows in the cable Y, as a result of an earth fault thereon, inducing flux in the magnetic circuit and causing the attraction of the armature. When this occurs the arm D, which normally holds up the flag E, is disengaged from the armature, and the flag E falls under gravity, thus indicating the existence of the fault. The setting screw G serves to adjust the sensitivity of the indicator. Arm J is manually moved to reset the indicator after the fault has been cleared. The loop B which clips on to the pole pieces A is removable to allow the loop to be placed around the cable, and may be reversed before replacement to obviate the effects of residual magnetism after a heavy fault current has flowed in the cable.
