Seaward Halo Ammeter

The Seaward Halo has been designed for measuring current flow on overhead line systems up to 40 kV (line to earth). The sensing unit 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 0A - 2000A. Using operator rods, the Halo is hooked over the conductor, and after 5 seconds the reading is stored and the instrument can be returned to ground level for the result to be recorded. The jaws are large enough to accommodate up to 50mm conductors. FEATURES Automatic latch-in at highest monitored current. Simple to use membrane switches.
