Abstract
The apparatus for measuring pulse energy includes integration means and serves to measure high-current disturbances carried by a cable. The apparatus is characterized in that it further includes a current-to-voltage converter (2) mounted on the cable (1), attenuation means (3, 4) coupling said converter to the integration means (5, 6), and a processing and storage assembly (12) coupled to the integration means and to an output display (20). Application: monitoring lightning protection equipment.
Claims5
An apparatus for measuring pulse energy, the apparatus being designed to measure the energy from high-current disturbances carried by a cable, said apparatus including:
- a current-to-voltage converter delivering at an output end thereof a voltage that is proportional to the current in said cable;
- an analog measurement circuit connected at an input end thereof to the output end of said current-to-voltage converter;
- and
- a processing and storage assembly having an input end, coupled to an output end of said measurement circuit, and an output end coupled to an output display;
- said apparatus being characterized in that said analog measurement circuit comprises at least two measurement branches, each of which includes an input attenuator (3, 4) and an output integrator (5, 6) having an input end coupled to an output end of said input attenuator, the attenuators in said branches being of different attenuations and having respective input ends connected in parallel to said current-to-voltage converter (2).
