What specific are you utilizing (e.g., Current, Inductive Voltage, or Electronic)?

IEC 61869-1, titled "Instrument transformers – Part 1: General requirements," defines the common characteristics for all types of instrument transformers. This includes traditional inductive current transformers (CTs) and voltage transformers (VTs), as well as modern electronic instrument transformers (EITs) and low-power instrument transformers (LPITs).

The scope of IEC 61869-1 includes:

Sets guidelines for liquid insulation, gas insulation, temperature rise limits, and short-circuit capability.

Digital interfaces for instrument transformers. Core Principles and Scope

Applies to newly manufactured transformers for high-voltage applications (> 1 kV AC or 1.5 kV DC) with frequencies from 15 Hz to 400 Hz. Accuracy Classes: What specific are you utilizing (e

Historically, instrument transformers were governed by the IEC 60044 series. However, as digital technology evolved and power systems grew more complex, the IEC technical committee (IEC/TC 38) restructured these rules into the IEC 61869 series.

Operational limits up to 1,000 meters above sea level. Higher altitudes require insulation correction factors. The scope of IEC 61869-1 includes: Sets guidelines

Requirements for liquid, gas, and solid insulation; earthing; and mechanical robustness.
