SCR Gate-to-cathode Resistance
One test that can be performed on SCRs that cannot be performed on SGCTs is
a Gate-to-cathode Resistance Test. Performing a Gate-to-cathode resistance
measurement will identify damage to a SCR by revealing either an open or
shorted gate-to-cathode connection. To test an SCR from gate-to-cathode,
disconnect the SCR gate leads from the self powered gate driver board and
measure the gate-to-cathode resistance on the SCR firing card Phoenix
connector as shown in
