ABSTRACT:
A thyristor connection which includes a plurality of thyristors each parallel to a voltage divider and a test device for individual testing of the individual thyristors. The test device includes a feeding circuit and a device for measuring the leakage current in one thyristor. The voltage divider for each thyristor is provided with output terminals for connecting the feeding circuit across a part of the voltage divider during measurement. There is a measuring section in series with such part of the voltage divider for connection of the measurement device. The thyristor connection is provided with an outer voltage divider in parallel with the connection which is provided with an output for connection of a point of the voltage divider to a pole of the feeding circuit.
