Halo Hook Ammeter
Halo Hook-On Ammeter for overhead lines.
The Halo has been designed for measuring current flow on overhead line systems up to 33 KV. The sensing unit, encased in a moulded plastic housing, feeds a circuit utilising solid state devices in a fibre glass tube.
Using operator rods the Halo is hooked over the conductor, after 5 seconds the reading is stored and the instrument can be returned to ground level for the result to be recorded.
