An electrical meter with integral AC current clamp is known as a clamp meter, clamp-on ammeter, tong tester, or colloquially as an amp clamp. A clamp meter measures the vector sum of the currents flowing in all the conductors passing through the probe, which depends on the phase relationship of the currents. Only one conductor is normally ...
Fluke Corporation is an American manufacturer of industrial test, measurement, and diagnostic equipment, including electronic test equipment. It was started in 1948 by John Fluke while he was employed at General Electric .
Clamp meters clamp around a conductor carrying a current to measure without the need to connect the meter in series with the circuit, or make metallic contact at all. Those for AC measurement use the transformer principle; clamp-on meters to measure small current or direct current require more exotic sensors, such as; hall effect based systems ...
The measurement of the electric current can be classified depending upon the underlying fundamental physical principles such as, Faraday's Law of Induction; Magnetic field sensors; Faraday effect; Transformer or current clamp meter, (suitable for AC current only). Fluxgate sensor, (suitable for AC or DC current).
Current clamp: Measures current without physical connection Curve tracer: Applies swept signals to a device and allows display of the response Cos Phi Meter: Measures the power factor Distortionmeter: Measures the distortion added to a circuit Electricity meter: Measures the amount of energy dissipated ESR meter
Megohmmeter M1101M. A Megohmmeter or insulation resistance tester, is a special type of ohmmeter used to measure the electrical resistance of insulators. [1] Insulating components, for example cable jackets, must be tested for their insulation strength at the time of commissioning and as part of maintenance of high voltage electrical equipment and installations.
