Title: A Comprehensive Guide to IEC 61000-4-13 and 61000-4-15 Standards

Introduction

IEC 61000-4-13 and 61000-4-15 are two of the most important international standards related to electromagnetic compatibility (EMC). These standards were developed by the International Electrotechnical Commission (IEC) and are widely recognized and adopted by manufacturers and regulatory authorities around the world. In this article, we will provide a comprehensive guide to IEC 61000-4-13 and 61000-4-15 standards, including their scope, requirements, and testing procedures.

IEC 61000-4-13:2019 - The Standard for Harmonics and Interharmonics

IEC 61000-4-13:2019, also known as the "Electromagnetic compatibility (EMC) - Part 4-13: Testing and measurement techniques - Harmonics and interharmonics including mains signalling at a.c. power port, low frequency immunity tests," is an international standard that focuses on harmonics and interharmonics, which are disturbances caused by non-sinusoidal electrical waveforms that can affect the performance of electronic devices and systems connected to the electric power network.

The standard defines a set of requirements for testing and measuring the electromagnetic compatibility (EMC) of electrical equipment and systems. The standard covers a wide range of topics, including the testing procedures for different types of equipment, the measurement techniques used to assess the EMC performance of equipment, and the criteria for determining the level of EMC interference.

One of the key requirements of IEC 61000-4-13:2019 is the requirement for equipment to have a low level of interference with other electrical systems and devices. The standard defines "interference" as any disturbance that is caused by a non-sinusoidal electrical waveform, including but not limited to electrical noise, over-saturation, and harmonic distortion.

To achieve this low level of interference, the standard requires equipment to have a specified level of immunity to interference from electrical noise and other sources. The level of immunity is determined by a measurement called "mains signalling," which involves the use of a test signal that is generated by a constant current source and then passed through the equipment being tested.

IEC 61000-4-15 - The Standard for Electrical Safety and System Protection

IEC 61000-4-15, also known as the "Electromagnetic compatibility (EMC) - Part 4-15: Safety requirements for electrical equipment - Essential safety requirements," is an international standard that focuses on electrical safety and system protection.

The standard defines a set of requirements for electrical equipment that are designed to ensure the safety of people and equipment in electrical installations. The standard covers a wide range of topics, including the requirements for electrical equipment to be resistant to electrical hazards, such as electrical fires and arc flash, and the requirements for electrical equipment to have a specified level of protection against electrical surges and other electrical abnormalities.

One of the key requirements of IEC 61000-4-15 is the requirement for electrical equipment to have a specified level of electrical isolation. The standard defines "electrical isolation" as the separation of electrical equipment from the electrical power supply, in order to prevent electrical hazards such as electrical fires and arc flash.

To achieve this level of electrical isolation, the standard requires electrical equipment to have a specified level of electrical isolation strength, which is determined by measuring the resistance of the equipment to electrical surges and other electrical abnormalities.

Conclusion

IEC 61000-4-13 and 61000-4-15 are two of the most important international standards related to electromagnetic compatibility (EMC). These standards provide a comprehensive set of requirements for testing and measuring the EMC performance of electrical equipment and systems, and for ensuring the safety of electrical equipment in electrical installations. By following the guidelines and requirements set out in these standards, manufacturers and other stakeholders can help to ensure that their products are compatible with the electrical power network and that they are safe and reliable for use.
