Abstract
PURPOSE: To prevent damage to a test piece or a malfunction by using the primary coil of a pulse transformer, which is connected to the transmission line in series, to function as inductance.
CONSTITUTION: The transmission line 22 is connected to the primary coil 24a of the pulse transformer 24 in series, and the resistance 26 by which current in the secondary coil is adjusted and the DC power supply 27 are connected to the secondary coil 24b in series. When the secondary coil 24b is opened by the switch 25, a self-inductance of the primary coil 24a is produced in the transmission line 22. On the other hand, the self-inductance that develops in the transmission line 22 can be reduced to the extent that it may be disregarded by closing the switch 25 to feed a required current to the secondary coil 24b.
