<p>Damage can be prevented even when a large current and high voltage load is imposed. A current generation device (1) uses the power supplied from a power supply device (2) to supply, to a test piece (9) under lightning protection test, current that simulates current flowing when lightning occurs. The current generation device (1) comprises: an electric double-layer capacitor that stores power supplied from the power supply device (2) and discharges the stored power; a semiconductor switch (3) for switching whether the power stored on the electric double-layer capacitor is supplied to the test piece (9) or not; and a protection portion (4) connected between the semiconductor switch (3) and the test piece (9) and used for, when current having a predetermined value or more flows through the semiconductor switch (3), disconnecting the connection between the semiconductor switch (3) and the test piece (9).</p> |
