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.
