The Seaward Halo Hook is a HV (high voltage) hook designed for measuring current flow on overhead (OHP) line systems up to 40kV (line to earth).
The sensing unit is encased in a moulded plastic housing and is fully screened against the effects of electrostatic fields. Extension rods can be added as an accessory to extend the operating length of the unit (sold separately).
The “Track” button switches on the instrument and in this mode will take a continuous measurement. The “Store” button will switch to a capture mode, and will store the highest reading measured – ideal for monitoring maximum demand over a period of time in electrical distribution networks.
The Halo Hook 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 from the LCD display. The jaws are large enough to accommodate up to 50mm conductors.
