3-phase AC current probes

April 2009 Maintenance, Test & Measurement, Calibration

The PRO-flex ACP3003_3 is a new 3-phase AC current probe utilising the Rogowski principle. It can be used to measure currents up to 3000 A from very low frequencies up to 10 kHz. The flexible and lightweight measuring head allows quick and easy installation in hard to reach areas and with large conductors.

Current ranges selectable by rotary switch of 30, 300 and 3000 A are selectable via a rotary switch, with output sensitivity of 100, 10 and 1 mV per amp. Accuracy is ±1% of reading and resolution of 0,1 A on a 30 A range, and 1 A on 300/3000 A ranges.

The three Rogowski measuring heads are connected to three integrators housed in a single enclosure. Three individual output cables are provided for connection to oscilloscopes or recorders via safety BNC connectors.
