ELECTRIC SPARK PULSE-TYPE CONTINUITY DETECTOR Russian patent published in 1997 - IPC

FIELD: electric measuring instruments, in particular, devices for monitoring the metal-based dielectric coating continuity. SUBSTANCE: the detector uses accumulator power supply 1, spark gap unit 2, sync pulse generator 3, AND gate 4, output transformer 5, probe electrode 6, signal/noise discriminator 10. After holding of a breakdown in the memory the logic "zero" from the inverted output of the memory location blocks the accumulator discharge; as a result, the energy loss is reduced at an arc discharge and ground fault of the probe electrode. EFFECT: enhanced efficiency. 1 dwg
