Abstract: The feasibility of accurate monitoring a high voltage is investigated, which based on measuring a current through a capacitor, which is already installed in the grid. A current clamp based ...

If you want to measure AC or DC current with an oscilloscope, a current clamp is a great way to do it. The clamp surrounds the wire, so you don’t need to break the connection to take your measurements ...

Fluke once again has solar power engineers in mind with a pair of instruments, both true-RMS, CAT III and rated to 1,500V: the 283 FC digital multimeter and the a283 FC wireless ac and dc current ...

The patch clamp technique underwent continual advancement and developed numerous variants in cardiac electrophysiology since its introduction in the late 1970s. In the beginning, the capability of the ...

Historically, researchers impaled giant squid, snail, and frog axons with electrodes to study nerve function by measuring ion channels. Today, electrophysiologists have enhanced their ability to ...

Abstract: This brief presents a high-voltage low-noise current clamp circuit for patch clamp electrophysiology systems. The circuit includes a novel programmable bidirectional current source spanning ...

Current clamps let you perform emissions and immunity measurements in signal and power cables. Unfortunately, clamps absorb some energy from the circuit under test in order to make a measurement. Thus ...

When you need to measure current flow through a wire, the normal method is to insert an ammeter in series with the cable. Using a clamp-on ammeter, or “Amp-clamp,” you don’t need to break the circuit.
