Q70 CE UL Split Core Clamp-On Current Transformer 0 - 3000A AC Busbar For Power Analyser
The model Q125 current clamp on measuring instrument can be used for a current vector for the copper bar or the power aluminum bus bar on-line detection.
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.
Clamp-on Current Transformer Current Clamp is a high-precision AC current converter, and can meet a variety of measuring instruments, It can be used along with many kinds of instruments and devices, such as energy meter spot calibrator, multifunctional meter, oscilloscope, digital multimeter, dual clamp Ground resistance tester, dual clamp phase volt ammeter.
GFUVE Current transformer clamp meters are equipped with rigid jaws of made of ferrite iron. The jaws are individually wrapped by coils of copper wire. Together, they form a magnetic core during measurements. Their basic operation is like that of a transformer. It works with one primary turn, or winding, which in nearly all cases is the conductor .
