Theory
In electrical and electronic engineering, a current probe is an electrical device with jaws which open to allow clamping around an electrical conductor. This allows measurement of the current in a conductor without the need to make physical contact with it, or to disconnect it for insertion through the probe. Current probes are typically used to read the magnitude of alternating current (AC) and, with additional instrumentation, the phase and waveform can also be measured. Some clamps meters can measure currents of 3000 A and more.
Applications
The Q125B is a high performance clamp on AC Current Probe with excellent transformation and low phase shift. The high quality magnetic core and uniform windings provide for accurate measurements up to 1000A AC/2000A AC/3000A AC. The Round jaw permits 125mm cable positionings. Provide excellent TRMS capabilities and reliable signal reproduction.
