摘要：
We have developed the wide band electronics for SQUID and measured short pulse currents simulating a signal in a degraded power electric cable. The SQUID driving electronics had a bandwidth as wide as 1.4 MHz and it could successfully detect currents of 3 μA with the width of 120 nsec. These results suggested that SQUIDs can be applied to the partial discharge measurement of power cables.
