What is BS EN IEC 61869 ‑ 10 – Instrument transformers about?
BS EN IEC 61869 ‑ 10 is an international standard that discusses additional requirements for low power passive current transformers for Instrument transformers. The purpose of the instrument transformer is to step down the voltage & current of the AC system because the level of voltage & current in a power system is extremely high.
BS EN IEC 61869 ‑ 10 is applicable to newly manufactured low-power passive current transformers with analogue output for use with electrical measuring instruments or electrical protective devices having a rated frequency from 15 H...
