What is BS EN 61000-4-4 - Electromagnetic compatibility about?
BS EN 61000 is a series on electromagnetic compatibility. Electromagnetic compatibility (EMC) is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment, by limiting the unintentional generation, propagation and reception of electromagnetic energy which may cause unwanted effects such as electromagnetic interference (EMI) or even physical damage in operational equipment. BS EN 61000-4-4 relates to the immunity of electrical and electronic equipment to repetitive electrical fast transients. BS EN 61000-4-4 gives immunity requirements and test procedures related to electrical fast transients/bursts and defines ranges of test levels and establishes test procedures.
The object of BS EN 61000-4-4 is to establish a common and reproducible reference for evaluating the immunity of electrical and electronic equipment when subjected to electrical fast transient/bursts on supply, signal, control, and earth ports. The test method documented in BS EN 61000-4-4 describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon.
Who is BS EN 61000-4-4 - Electromagnetic compatibility for?
BS EN 61000-4-4 on electromagnetic compatibility is useful for:
- Telecommunication equipment manufacturers
- Electrical equipment manufacturers
- Design engineer
- Quality control personnel
- Research and development facilities
Why should you use BS EN 61000-4-4 - Electromagnetic compatibility?
The goal of electromagnetic compatibility is the correct operation of different equipment in a common electromagnetic environment. It is also the name given to the associated branch of electrical engineering. BS EN 61000-4-4 discusses the repetitive fast transient, which is a test with bursts consisting of several fast transients, coupled into the power supply, control, signal and earth ports of electrical and electronic equipment. Significant for the test is the high amplitude, the short rise time, the high repetition rate, and the low energy of the transients.
The test as described in BS EN 61000-4-4 is intended to demonstrate the immunity of electrical and electronic equipment when subjected to types of transient disturbances such as those originating from switching transients (interruption of inductive loads, relay contact bounce, etc.).
BS EN 61000-4-4 defines test voltage waveform, range of test levels, test equipment, verification procedures of test equipment, test set-up, test procedures. BS EN 61000-4-4 gives specifications for laboratory and post-installation tests. Using BS EN 61000-4-4 you can understand immunity requirements and test procedures related to electrical fast transients/bursts and define ranges of test levels and establish test procedures.
What’s changed since the last update?
