Looking for IEEE or Industry Standards Supporting Use of Current-Limiting Devices

Hello everyone,
We are planning to install Current Limiting Protector (CLiP) devices at our substation and are looking for any industry standards or references that explicitly recommend or recognize the use of current-limiting devices to reduce fault current.

If anyone can point me to the applicable standard references, white papers, or technical documentation that support the use of CL devices in medium voltage system, I’d greatly appreciate it.

Thanks in advance for your help!
 
If you are a utility, you could use engineering judgement to apply it using the current limiting curves provided by G&W.

If you are not a utility and need to follow the NEC, then there is no such permission to use a current limiting device like the CLiP to reduce fault current without testing it with the downstream equipment to show it works as a combination. The NEC actually does not have any permissions like a series rating for low voltage OCPDs, but if it is factory tested as an assembly, most would allow it.

Other than magazine literature, I do not think there is any consensus documents like IEEE allowing or promoting this type of product.

We are utility. Thank you for the help.
