: Now covers applications with rated frequencies from , as well as DC applications.
This part applies to newly manufactured instrument transformers (current, inductive voltage, capacitor voltage, electronic, etc.) used for electrical measurement and protection at frequencies from 15 Hz to 100 Hz. iec 61869-1 pdf free download
While official IEC standards generally require purchase, you can find various draft versions and regional adoptions like or the Russian ГОСТ IEC 61869-1-2015 available for free preview or download through regional standards portals. Deep Feature: The "Product Family" Restructuring : Now covers applications with rated frequencies from
This part of the series provides for instrument transformers. It serves as a "product family standard" and must be used alongside specific parts (like Part 2 for current transformers). IEC 61869-9:2016 Deep Feature: The "Product Family" Restructuring This part
A significant portion of IEC 61869-1 is dedicated to the verification of performance through rigorous testing. It defines three categories of tests:
The IEC 61869-1 standard covers various aspects of instrument transformers, including:
