Seaward Halo Hook Ammeter - 205A910

The Seaward Halo Hook has been designed for measuring current flow on overhead line systems up to 40000 volts (line to earth) with jaws wide enough to accomodate up to 50mm conductors. The sensing unit of this hook-on ammeter is encased in a moulded plastic housing and is fully screened against the effects of electrostatic fields. The RMS reading digital display is mounted in the fibre glass tubing body of the instrument and has a measurement range of 0 - 2000 amps. Using operator rods the Seaward 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.
