In analog CTs, the load on the secondary (the burden) had to be carefully calculated. Too much burden? Saturation, errors, heating. In IEC 61869-9, the "burden" is irrelevant. The digital output is identical whether the relay is 5 meters away or 5 kilometers away. a Comparative Review of IEC61850-9-2 and IEC 61869-9

Yes, you read that correctly. In the analog world, you couldn't "spoof" a CT – you'd have to physically inject a current. In the digital world, a compromised merging unit could inject false fault values. So the standard includes provisions for authenticity and integrity (e.g., using a digital signature or MAC). We are now signing amps and volts as if they were blockchain transactions. The IEC 61869 (IEC 61869 – Communication Networks

: Its primary goal is to ensure that a Merging Unit from one manufacturer can "talk" seamlessly to a protection relay from another. 2. Key Technical Features
