Title: IEC 61000-4-13:2019: A Technical Article on Electromagnetic Compatibility and Interference
Introduction:
IEC 61000-4-13:2019 is an essential standard for evaluating the electromagnetic compatibility (EMC) of electrical and electronic equipment. This international standard, also known as "Electromagnetic compatibility - Part 4-13: Testing and measurement techniques - Harmonics and interharmonics including mains signalling at a.c. power port, low frequency immunity tests, " is developed by the International Electrotechnical Commission (IEC) and 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.
In this article, we will provide a technical explanation of IEC 61000-4-13:2019, its purpose, and the testing process.
What is IEC 61000-4-13:2019?
IEC 61000-4-13:2019 is an international standard that defines a set of conditions for simulating realistic electromagnetic environments. It provides guidelines for conducting electromagnetic interference (EMI) tests, including the frequency and power level of the radio transmitters, as well as the expected level of interference. The standard focuses on immunity tests for electrical and electronic equipment against electromagnetic fields caused by radio transmitters.
The Purpose of IEC 61000-4-13:2019
The main purpose of IEC 61000-4-13:2019 is to define a set of conditions that simulate realistic electromagnetic environments. By subjecting electrical and electronic equipment to these tests, manufacturers can assess the performance and susceptibility of their products to electromagnetic interference from radio transmitters or other sources. The standard aims to ensure that products are capable of operating without being affected by electromagnetic interference from radio transmitters or other sources.
The Testing Process
The testing process for IEC 61000-4-13:2019 involves a series of steps, including:
1. Preparing the equipment: The first step is to prepare the electrical and electronic equipment for testing. This includes connecting the equipment to a power supply, grounding the equipment, and ensuring that it is in a stable and secure environment.
2. Calibrating the equipment: The next step is to calibrate the equipment to ensure that it is operating within the expected parameters. This involves setting the frequency and power level of the radio transmitters, as well as the expected level of interference.
3. Conducting the test: The equipment is then placed in the test chamber and the test is conducted. The test chamber is designed to simulate the electromagnetic environment in which the equipment will be used.
4. Measuring the interference: Once the test is complete, the equipment is measured to determine the level of interference it has experienced. This is done by measuring the voltage and current of the equipment, as well as the frequency and power level of the radio transmitters.
5. Evaluating the results: The results of the test are then evaluated to determine the performance and susceptibility of the equipment. This includes measuring the immunity to electromagnetic interference, as well as the level of interference experienced by the equipment.
Conclusion:
IEC 61000-4-13:2019 is an essential standard for evaluating the electromagnetic compatibility of electrical and electronic equipment. By subjecting equipment to these tests, manufacturers can ensure that their products are capable of operating without being affected by electromagnetic interference from radio transmitters or other sources. The testing process involves preparing the equipment, calibrating it, conducting the test, measuring the interference, and evaluating the results..
