How to test the Thyristors 2

[mannumss]

we have Disk type thyristors which are used to control the Reactor ( used in SVC circuit ), how to test the new Thyristor is it OK or not? Is it possible by multitester or any other method? this thyristor having 2 wires...any ideas are helpful for me thanks in advance.

Agree with Scotty...not enough current

My all thyristors are using in TCR ( Thyristor control reactor )high Voltage circuit and i dont know weather it is GTO or Not. but it should be latch as per my Knowledge. i used 12 VDC source as i mentioned through strong Battery charger and lamp is 12V, 21Watt. OR any other method to test the thyrsitor. can someone give me another circuit. i can give u thyristor type EGR03-05 , 250 v 1000 A
thank u
