Overview
IEC TR 60725:1981 is a technical report published by the International Electrotechnical Commission (IEC) focusing on the considerations for reference impedances used in evaluating the disturbance characteristics of household appliances and similar electrical equipment. This report documents the rationale and data behind the reference impedance value of 0.4 + j0.25 ohm, which has been incorporated into the related standard IEC 60555.
As a technical report rather than a mandatory standard, IEC TR 60725 provides important background information and guidance on selecting and applying reference impedances to ensure consistent and reliable measurement of electrical disturbances such as conducted emissions.
Key Topics
Reference Impedance Definition
Explanation of the complex impedance value (0.4 + j0.25 ohm) used as a benchmark in disturbance measurements, combining both resistance and reactance components.Basis for Impedance Selection
Factors and historical data that influenced the establishment of the reference impedance, including network characteristics and typical installation conditions for household appliances.Disturbance Characteristics Assessment
How the reference impedance impacts the measurement and interpretation of conducted disturbances emitted by electrical equipment.Technical Report Status
Clarification that IEC TR 60725 serves as an informative document supporting standards like IEC 60555 rather than specifying mandatory requirements.
