Abstract
A device comprises a circuit board, a Rogowski coil on the circuit board, persistent data storage on the circuit board, and a control circuit on the circuit board for collecting values representing current sensed by the coil, and storing the values in the persistent memory.
Claims7
A method, comprising:
- subjecting an aircraft structure to an electromagnetic effect (EME) event comprising an artificial source of EME current;
- detecting the EME event on the aircraft structure using EME current sensing devices provided on circuit boards fastened to the aircraft structure;
- storing EME current values for a first period immediately preceding the EME event;
- storing EME current values for a second period after the EME event has been detected;
- and
- constructing a full current waveform for the EME current values stored during the first and second periods, wherein the full current waveform includes a rise time of current induced by the EME event.
