Abstract

PURPOSE: To enable measurement to be made highly accurately and easily without being affected by displacing currents by converting the gate current signal of a thyristor to a light signal, and transmitting and inputting this to a measuring device.
CONSTITUTION: The gate current signal of a thyristor 20 held at a high potential is converted to a light signal by a light emitting element 24. This signal is transmitted to a photodetector 36 via a light guide 38, and the light signal is again converted to an electric signal by this photodetector 36. Further this electric signal is inputted to a measuring device 30 held at a ground potential, whereby the gate current of the thyristor 20 is measured or observed.
