Transient Surge protection for Transmitters

07/18/2015 12:32 AM

The transmitters by various vendors provide ranges of voltage for surge protection limit. Eg: 1kV, 4kV
What i learnt is For low voltages surge protection in accordance with ANSI/IEEE C37-90A-1974.Can anyone please share the standard.. details are not available on google and vendors informed that ranges are as per there own standard. i need to cross-check with ranges which vendors provide.
Pls. share if any one known about selection criteria for transmitters of 24Vdc shall fall in..
P.S- Lightning arrestors are already provided for complete power plant!

Here it is.

IEEE Guide for Surge Withstand Capability (SWC)

Ask vendors to respond to your request for quote after you figure out what it is that you want.
Only you know what you need. We don't and suppliers don't until you tell them what it is.

Maybe you can deduce some values from the graphs on this app note from Dataforth (signal conditioners).
