Three-phase AC current probe

21 January 2009 Test & Measurement

The PRO-flex ACP3003_3 is a new three-phase AC current probe from Proflex. 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, are 30 A, 300 A and 3000 A, with output sensitivity of 100 mV/10 mV/1 mV per amp. The probe boasts accuracy of ±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, recorders etc., via safety BNC connectors.
