Current clamps Pinces ampèremétriques pour courant AC Current measurement Série MN A modern method for measuring electrical currents Several Chauvin Arnoux® clamps are patented for their unique circuitry and design. Circuit magnétique Iron core Conductor input This same principle is applied to a current clamp (ﬁgure 2). The articulated magnetic core holds the coil B2 and clamps onto a conductor where the current I1 is ﬂowing. B1 is simply the conductor where the user is measuring the current with the number of turns N1 equal to one. The current sensor clamped around the conductor provides...

Current clamps Pinces ampèremétriques pour courant AC Current measurement Série MN A modern method for measuring electrical currents µ0.n di x S. 2π.r dt µ0 = vacuum permeability S = surface area of a turn n = number of turns r = core radius • Theory of Operation (Hall effect) Unlike on traditional AC transformers, AC/DC current measurement is often achieved by measuring the strength of a magnetic ﬁeld created by a current-carrying conductor in a semiconductor chip using the Hall-effect principle. When a thin semiconductor (ﬁgure 6) is placed at right angles to a magnetic ﬁeld (B), and a...

Current clamps Pinces ampèremétriques pour courant AC Current measurement Série MN A modern method for measuring electrical currents SELECTING A CURRENT PROBE Answering the following questions will help you to select the appropriate clamp for your applications: Other factors you may want to consider: • What is the working voltage of the conductor to be measured ? 1. Determine if you are measuring AC or DC (DC current clamps are categorized as AC/DC because they measure both). • Chauvin Arnoux clamps must not be used above 600 volts (see speciﬁcations). 2. What is the the maximum current you...

Current clamps for AC current Pinces ampèremetriques pour courant AC MINI series Serie MN MINI SERIES Small, compact and particularly resistant, this range of miniature clamps is designed for measurements from a few milli-amperes to 150 A AC. Their shape makes them very practical in conﬁned spaces, such as circuit-breaker boards, control panels or control boxes. They are ideal for use with multimeters. There are two types of MINI clamps. The ﬁrst type operates like a traditional current transformer and provides a current output (mA) which can be used with multimeters, loggers or instruments...
