Absorbing Clamps to measure EMI Emissions according to CISPR 14 orEN 55014
The absorbing clamps also known as ferrite clamps are used for measuring radio noise
power in lieu of radiated emissions measurements. These absorbing clamps meets
CISPR publication 14 (EN 55014) for the measurement of interference from household
appliances, electrical tools and similar apparatus. It measures radio noise power
generated and fed through the power cables of these products above 30 MHz.
The absorbing clamp consists of a calibrated ferrite current transformer operating in the
frequency range of 30-1000 MHz and two groups of ferrite rings. The ferrite rings acts as
an absorbers of energy and stabilizes impedance. One set of ferrite rings surrounds the
lead from the transformer to the EMI meter to minimize standing waves. The second
group of ferrite rings surround supply cable from the equipment under test. These rings
act as an absorber of energy and an impedance stabilizer to isolate the equipment under
test (EUT) from the external power source. These rings are made up of two halves.
Therefore, the power cable from the EUT can be placed inside the aperture of the rings.
Calibration
All Com-Power absorbing clamps are individually calibrated before shipment with
equipment traceable to National Institute of Standards and Technology (NIST). The data
and the certificate of calibration are shipped with each unit.
