Seaward Overhead Halo Hook Ammeter

Description

The Seaward Overhead Halo’s designed for measuring current flow on overhead line systems up to 40 kV (line to earth). The sensing unit’s encased in a moulded plastic housing and fully screened against the effects of electrostatic fields.

The RMS reading digital display’s mounted in the fibreglass tubing of the instrument and has a measurement range of 0A-2000A. Using operator rods, the Halo’s hooked over the conductor, and after 5 seconds the reading’s stored and the instrument can return to ground level for the result to take place on record. The jaws are large enough to accommodate up to 50mm conductors.
