IEC specifications for SCRs

[shipelec]

Hello, everyone,

I am replacing some Silicon Controlled Rectifier units that convert 600 VAC to 750 VDC for some DC propulsion motors. I would like to reference specifications for performance and testing. IEEE 45 (2002 edition) says it should comply with IEC 60146 and 61136. Somebody gave me IEC 92-501 (which is dated 1984). Is there someplace I can find out which specification applies? And does IEC 60146 replace IEC 92-501?

Have a look at

and you will find the upto date reference of the standard you need

I've already looked at a couple of IEC sites. Their history doesn't seem to go that far back. I was hoping there was someone on this forum that had some history and would know whether IEC 92-501 was replaced with IEC 60146.
