BS EN 61800-3:2018+A1:2018, also known as BS EN 61800-3:2018+A1:2018, is a technical standard that specifies the requirements and test methods for adjustable speed electrical power drive systems (PDS) in terms of their electromagnetic compatibility (EMC). This international standard was published by the European Committee for Electrotechnical Standardization (CENELEC).
Electromagnetic Compatibility (EMC)
Electromagnetic Compatibility, commonly referred to as EMC, is the ability of electrical and electronic devices to operate in close proximity without causing or suffering from interference. Interference can occur when the operation of one device affects the performance of another nearby device.
The EMC of a PDS refers to its ability to function correctly in its intended electromagnetic environment without causing electromagnetic disturbances that could affect other equipment or being affected by such disturbances from other equipment. The BS EN 61800-3:2018+A1:2018 standard ensures that adjustable speed electrical power drive systems comply with specific EMC requirements.
Key Requirements of BS EN 61800-3:2018+A1:2018
The BS EN 61800-3:2018+A1:2018 standard outlines several key requirements that adjustable speed electrical power drive systems must meet regarding electromagnetic compatibility:
Immunity to electromagnetic disturbances from other equipment operating within specified limits.
Low emission of electromagnetic disturbances to prevent interference with other devices.
Maintenance of optimal performance when subjected to electromagnetic disturbances within specified limits.
Mitigation measures to minimize the possibility of malfunction or damage due to electromagnetic disturbances.
Test Methods for Compliance
The BS EN 61800-3:2018+A1:2018 standard also specifies the test methods to assess compliance with the EMC requirements. These tests include:
Radiated emission measurements to evaluate the level of electromagnetic radiation emitted by the PDS;
Conducted emission measurements to assess the level of conducted disturbances, including voltage fluctuations and harmonics;
Immunity measurements to determine if the PDS remains functional despite being subjected to various electromagnetic disturbances.
Based on the test results, the PDS is classified into different categories, indicating its ability to function properly in different operational environments.
In conclusion, BS EN 61800-3:2018+A1:2018 is an important technical standard that ensures adjustable speed electrical power drive systems comply with electromagnetic compatibility requirements. By adhering to this standard, manufacturers can guarantee that their products function correctly without causing or suffering from electromagnetic interference, thereby promoting safer and more reliable operation of these systems.
