When a standard like ISO/HL7 61869-9 is implemented correctly:
Instrument transformers – Part 9: Digital interface for instrument transformers . 61869-9
IEC 61869-9 was created to succeed and expand upon the legacy 9-2LE guideline. It standardizes communication specifically for instrument transformers—including both legacy inductive types and modern Low-Power Instrument Transformers (LPITs)—while offering vastly superior grid flexibility.

To understand why this matters, we need to look at the "RIM" (Reference Information Model). The RIM is the backbone of HL7 Version 3. It is a rigorous, scientific model that defines every possible piece of data in healthcare (from a patient's name to a surgical procedure). IEC 61869 Sampled Values protocol - Typhoon HIL
that enables fully digital substations. It is essential for:
The standard specifies:
