Claim 1
Independent Claim
166 words
A DEVICE ATTACHABLE TO A PYLON FOR DETECTING FAULTY INSULATORS WHICH CAUSE SHORT CIRCUITS IN HIGH TENSION LINES CARRIED THEREBY, COMPRISING, A NON-MAGNETIC CASING ATTACHABLE TO THE PYLON, A PAIR OF SPACED FERROUS STRIPS POSITIONABLE ADJACENT TO A METALLIC ELEMENT OF THE PYLON TO FORM A LOW RELUCTANCE MAGNETIC PATH WITH SAID METALLIC ELEMENT; AN AIR GAP BETWEEN SAID FERROUS STRIPS IN SAID CASING, AN ARMATURE PLATE HAVING A PORTION OF FERROUS MATERIAL DISPOSED IN SAID AIR GAP, AN INDICATOR PLATE JUXTAPOSITIONED WITH RESPECT TO SAID ARMATURE PLATE AND SLIDABLE BY GRAVITY FROM AN UPPER NON-INDICATING POSITION TO A LOWER INDICATING POSITON, AND A LATCHING ELEMENT CARRIED BY SAID ARMATURE PLATE AND NORMALLY RETAINING SAID INDICATOR PLATE IN THE UPPER NON-INDICATING POSITION, WHEREBY WHEN A FAULT OCCURS IN THE INSULATORS OF THE PYLON, A MAGNETIC FIELD IS CREATED SUFFICIENT TO CAUSE SAID FERROUS STRIPS TO MOVE SAID AMATURE TO RELEASE SAID LATCHING ELEMENT, PERMITTING SAID INDICATOR PLATE TO MOVE DOWNWARDLY BY GRAVITY TO ITS INDICATING POSITION.
