What is IEC 61000-4-78:2019 ?

IEC 61000-4-13:2019 is an essential standard for evaluating the electromagnetic compatibility (EMC) of electrical and electronic equipment. It is part of the IEC 61000-4 standard, which is a set of guidelines for testing and measurement techniques for EMC.

IEC 61000-4-13:2019 provides guidelines for conducting immunity tests, which are used to assess the performance of electrical and electronic equipment in the presence of electromagnetic interference. The tests are designed to simulate realistic electromagnetic environments and are conducted at a variety of frequencies and power levels.

The standard defines a set of conditions for conducting the tests, including the frequency and power levels of the electromagnetic interference, the duration of the exposure, and the testing procedures. It also provides guidelines for evaluating the performance of the equipment, including the measurement of key parameters such as the total impedance, the common-mode current, and the differential output.

The Testing Process

To comply with the requirements of IEC 61000-4-13:2019, manufacturers must conduct the necessary tests on their products. These tests typically involve subjecting the equipment to a series of electromagnetic interference sources, and then measuring the performance of the equipment in the presence of the interference.

The testing process typically consists of several steps, including the preparation of the test setup, the calibration of the test equipment, and the testing itself. The test equipment is typically designed to simulate the electromagnetic interference that the equipment is expected to encounter in real-world environments.

The testing procedure is defined by the IEC 61000-4-13:2019 standard, and it is typically conducted in an anechoic chamber or a controlled environment that is free from external interference. The equipment is then exposed to the electromagnetic interference for a specified duration, and the performance of the equipment is evaluated based on the guidelines provided in the standard.

Conclusion

IEC 61000-4-13:2019 is an essential standard for evaluating the EMC of electrical and electronic equipment. It provides guidelines for conducting immunity tests that simulate realistic electromagnetic environments. By subjecting their products to these tests, manufacturers can ensure that their equipment is capable of operating without being affected by electromagnetic interference from radio transmitters or other sources.
