IEC TR 61000-2-1 is a technical report (part of the IEC 61000 series) titled "Electromagnetic compatibility (EMC) - Part 2: Environment - Section 1: Description of the environment - Electromagnetic environment for low-frequency conducted disturbances and signalling in public power supply systems". It provides information or description on the various types of disturbances that may occur in public power supply systems. The document considers various disturbance phenomena, including the following:

Harmonics;
Inter-harmonics;
Voltage fluctuations;
Voltage unbalance;
Voltage dips and short supply interruptions;
Main signaling;
Power frequency variation;
d.c. components.

This report also outlines the basic definition of key EMC-related terms, such as Electromagnetic compatibility (EMC), Electromagnetic compatibility level, Electromagnetic disturbance, disturbance level, limit of disturbance, Immunity level, and Electromagnetic susceptibility. IEC TR 61000-2-1 serves as a reference document for those associated parts that specify compatibility level values.
