Wide-Band Attenuator
Advantages of using with a terminated LILCO current transformer:
•Extended low frequency cut off point in Hz
•Reduced droop in %/ms
•Increased I-t capability in mA s
•Reduced output in V/A
•Extended low frequency cut off point in Hz
•Reduced droop in %/ms
•Increased I-t capability in mA s
•Reduced output in V/A
The ATT10BNCS attenuator is used to extend the low frequency cut-off point by factor 10, to increase I-t (product of current and time), and to reduce droop and output factor of PMK's terminated LILCO current transformers.
The attenuation of the output of a terminated LILCO current transformer is achieved by reducing it's output resistance of the current transformer. The LILCO current transformer's internal shunt resistor is normally 50 Ω. By applying ATT10BNCS to the output of the transformer it's output in V/A is reduced by the factor of 10.
