DESCRIPTION

The High Voltage Digital Ammeter, HVA-2000,
measures line current on overhead and underground
secondary voltage, distribution voltage and
transmission voltage distribution systems up to 500kV.

The HVA-2000 measures current from 1 Amp up to 2000
Amps and current is displayed in the large easy to read
four digit display.

The HVA stores the four most recent current readings,
typically three individual phase currents and a neutral
current for easy review after making measurements.
