High Voltage Digital Ammeter

The HALO^® is a high voltage digital ammeter for use on power distribution systems designed to take True RMS AC current measurements. Its open-core design allows the user to quickly hook it over a conductor from the end of a hotstick and obtain a current reading in amperes. The HALO can be used to take spot load measurements on a single phase, as well as take readings on all three phases to determine load balance.

There are two models, the HALO I and the HALO II. The HALO I has a peak-hold mode so the reading is stored on the display until reset. The HALO II includes the peak-hold mode and also a tracking mode that allows the user to view continuous changes on the display. The unit can be used on any voltage up to 69kV system voltages. It is available with either a hook-style or fork-style sensing head. The HALO can be used over insulated cable. However, it cannot be used over shielded cable, such as the concentric neutral.
