multimeters, recorders, power analysers, safety testers etc.
Clamp-on CT's & Flexible AC Current Probe; Split Core CT's ( AAC to
AAC ) / (AAC to AAC) Flexible Current Transformer (FCT Series)
Clamp-On Current Transformer (CCT Series) High Precision CT's;
Clamp - On AC Transformer.
GFUVE Q8 Series of Clamp-On Current Transformer's are designed for
fast and easy installation. Clamp-On CT uses Permalloy Magnetic
Core or Silicon Amorphous Core, with characteristics of small size.
high precision, good stability and strong anti-interference
ability.
A common form of current clamp comprises a split ring made of
ferrite or soft iron. A wire coil is wound round one or both
halves, forming one winding of a current transformer. The conductor
it is clamped around forms the other winding. Like any transformer
this type works only with AC or pulse waveforms, with some examples
extending into the megahertz range.
