The is far more than a digital document—it is the foundational reference for safety, reliability, and interoperability in instrument transformers. Whether you are designing a new substation, testing equipment in a lab, or writing a tender for a renewable energy project, this standard ensures that all stakeholders operate from a single, trusted source of truth.

This is a critical section for safety. It details power-frequency withstand voltage, lightning impulse tests, and partial discharge limits. The standard ensures that transformers can survive overvoltages without failing catastrophically. This is a critical section for safety

IEC 61869-1 applies to newly manufactured instrument transformers intended for use with electrical measuring instruments, protection relays, and similar devices in 50/60 Hz AC power systems (typically rated up to 800 kV and above). It covers: lightning impulse tests
