Q40 GFUVE Alternating Current Clamp On Current Transformer Ratio 500A / 5V 2.5 Meter Cable
The GFUVE Q40-2 Split Core Current Sensor has high frequency available for oscilloscope, excellent linearity performance. The distinct jaw shapes to be used for hooking or prying around the conductor.
In electrical and electronic engineering, a current clamp or 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 clamps are typically used to read the magnitude of alternating current and, with additional instrumentation, the phase and waveform can also be measured. Some clamp meters can measure currents of 1000 A and more. Hall effect and vane type clamps can also measure direct current.
GF438II PQA with Three 500A Clamp-On Current Transformers, 40mm Model: Q40 This Power power quality analyzer set comes with 4pcs Q40 clamp-on current transformers that have a 10mA to 500Arms measuring range and a 40mm diameter maximum conductor size.
The GFUVE clamp-on current transformer is very popular with our customers due to its fast and easy installation Produced with amorphous silicon core or permalloy core, this product features small size, high precision good stability and good anti-interference This product is widely used for measuring power and energy in the fields of electric power, communication and monitoring system. Besides the high precision and the small phase error this clamp-on current transformer can be used to measure a wide variety of electric parameters without disconnecting the exiting electric system.
