Description
A 19-inch version is available for the substation building, and a compact version for the switchyard. Time synchronization is done via 1PPS or IEEE 1588. Network redundancy is supported through PRP and HSR. This allows existing instrument transformers to be connected to a digital substation without replacing them.
