Chauvin F407 Power Clamp

The Chauvin F407 harmonics clamp can be clamped around a conductor with just one hand. With a measurement range up to 1500A, their ability to measure AC or DC currents and their exceptional jaw opening capacity, these clamps are ideal for use on switchboards in small or large industrial installations. Equipped with a fast 12-bit TRMS digital acquisition system, F407 clamps offer particularly accurate measurements. Due to their large bandwidth and high crest factor, these clamps guarantee accurate measurements whatever the type of signal. They are particularly comfortable to read because of their backlit LCD display, offering contrasts and a viewing angle which are unprecedented for this type of instrument. Quick, Safe Implementation Users select the required measurement with the rotary switch and then clamp the conductor or hook up their measurement leads. To obtain further details on the measurement in progress, all you have to do is press the corresponding function on the front panel: HOLD, Min/Max, etc. Harmonics By monitoring voltage and current harmonics, it is usually possible to determine which loads are polluting the electrical network. With the F407 clamp, the harmonics mode enables you to: determine the harmonic currents produced by non-linear loads, analyse the problems caused by these harmonics, depending on their order (heating of neutral, motors, etc.). THD measurement (THD-f and THD-r) can be used to quantify the harmonics present on the network. Recording to detect even intermittent faults This is an important advantage for technicians in the field. In the event of random faults, they no longer have to wait for them to occur: the paperless recorder function enables them to record the relevant parameters over time at a rate which they can define. The instrument automatically stores the average, minimum and maximum values in all the modes (voltage, current, power, etc.). All the parameters will be stored in the instrument’s memory. The programmable acquisition rate allows users to define the recording duration possible on the instrument. All the recordings will then be available as trend curves for analysis.
