Current clamps for AC current Pinces ampèremetriques pour courant AC B SERIES The only model in the B series, the B102 is designed to measure earth leakage currents caused by insulation faults. It enables the fault to be located and diagnosed before failure occurs thus avoiding installation shutdown. It is designed specifically for locating low-current faults on high-current circuits. The B102 measures differential or leakage current from 500 μA upwards and may be used to measure currents up to 400 A in continuous use (400 A max.). As a leakage current detector, the B102 can be used on single or multiphase systems whether the currents are in or out of phase, balanced or unbalanced. The B02 may be used simply as a high-precision clamp-on current probe. With its 115 mm jaw opening and dynamic measurement range from 500 μA to 400 A, the B102 is a versatile instrument, highly useful in the analysis of unbalanced circuits, leakage currents and earth loop currents. When operated in conjunction with an artificial neutral, the B102 can also be used to measure fault currents on 3-phase circuits with no neutral. The B102 has two measurement ranges, 1 mV/mA or 1 mV/A. (1) AN1 artificial neutral box (see capter 13) Non-contractual document

Current clamp for AC current Pinces ampèremetriques pour courant AC Model B102 (clamp for leakage currents) Current DESCRIPTION The B102 clamp measures leakage currents or residual currents as low as 500 µA and can be used with multimeters equipped with a calibre in mV AC. The B102 clamp measures the currents flowing in earth loops as well as leakage currents. It can be used on live installations to detect insulation faults on the earth circuits of single and three-phase networks. For three-wire three-phase systems, use the artificial neutral box.
