What is BS EN 61800-3:2018+A1:2020?

BS EN 61800-3:2018+A1:2020, also known as European Standard for Adjustable speed electrical power drive systems - Part 3: EMC Product Standard, applies to electrical power drive systems (PDS) with adjustable speed, typically used in industrial applications. It provides guidelines and requirements for electromagnetic compatibility (EMC) of these systems, ensuring their safe and reliable operation.

Importance of BS EN 61800-3:2018+A1:2020

In today's technologically advanced world, the use of adjustable speed electrical power drive systems is becoming increasingly prevalent in various industries. These systems control the speed and torque of motors, allowing for efficient and precise control of machines and processes. However, their widespread use also brings challenges in terms of electromagnetic compatibility.

Electromagnetic interference (EMI) can cause malfunctions or failures in adjacent electronic equipment, leading to potentially hazardous situations or costly downtime. Therefore, compliance with standards such as BS EN 61800-3:2018+A1:2020 is crucial to ensure proper functioning of adjustable speed electrical power drive systems and to minimize the risk of EMI-related issues.

Key Requirements of BS EN 61800-3:2018+A1:2020

The standard encompasses a wide range of requirements to ensure electromagnetic compatibility of adjustable speed electrical power drive systems. Some key requirements include:

Limiting emissions: The standard specifies maximum allowable levels of conducted and radiated emissions to minimize the potential for interference with other equipment.

Immunity to external disturbances: PDS should be designed to withstand common electromagnetic disturbances, such as electrostatic discharge, fast transients, and voltage dips.

Harmonic content: BS EN 61800-3:2018+A1:2020 sets limits on the harmonic content of the electrical power drive systems to prevent excessive distortion of the power supply.

Protection against EMI: The standard requires appropriate measures, such as shielding, filtering, and proper grounding, to protect both the PDS itself and other nearby equipment from electromagnetic interference.

Benefits of Compliance

Complying with BS EN 61800-3:2018+A1:2020 offers several benefits to manufacturers, users, and society as a whole. Some key benefits include:

Reliable operation: By meeting the standard's requirements, adjustable speed electrical power drive systems are less likely to experience malfunctions or failures due to electromagnetic interference, ensuring their reliable operation.

Compatibility with other devices: Compliant systems are designed to minimize their impact on other electronic devices, allowing for harmonious coexistence in shared environments.

Reduced downtime and costs: Compliance reduces the risk of EMI-related failures, minimizing costly downtime and potential repairs or replacements.

Safety and environmental considerations: Adhering to the standard ensures that adjustable speed electrical power drive systems meet safety regulations and contribute to environmental protection by reducing overall electromagnetic pollution.
