FIELD: service of distribution of 6-10 kV electric networks.
SUBSTANCE: indicator can be used for finding damaged parts in distribution network at short circuit breakdown. Indicator is installed in distribution and transformer stations and has plate made of material having paramagnetic, diamagnetic or ferromagnetic properties, vertical axis of rotation and horizontal arm. Top and lower ends of plate are bent to one side at angle of 90 deg and have several pairs of holes disposed symmetrically to adjust torque. Plate is mounted with selected pair of holes onto vertical axis of rotation which has lower end fixed to horizontal arm. Arm is attached to vertical member of bus.
EFFECT: simplification of design; reliability of operation.
