1 Scope

In order to ensure the electromagnetic compatibility (EMC) of electrical and electronic equipment or systems used in industrial, commercial and residential environments, "Electromagnetic

This section of the Guidance on Capacity Building and Mitigation gives general requirements and guidance on mitigation methods. Suitable for those sensitive electrical or electronic equipment

And systems and installations that may have a high emission level that may degrade the overall ambient electromagnetic (EM) environment, users, and a range of

manufacturer. Mainly applicable to new facilities, but also to the expansion and improvement of existing facilities where economic conditions permit.

Suggestions for some specific issues are given elsewhere in the EMC Guide to Installation and Mitigation. For example. Grounding system

Including the design and implementation of grounded electrodes and grounded networks, the design and implementation of lapsing instruments or systems with earth or grounded networks, suitable cables

As well as the design and implementation of mitigation measures including shielding housings, high frequency filters, isolation transformers and surge protection devices.

The recommendations on EMC aspects of the facilities given in this section are neither safety nor the effective transmission of electricity in the facility

Lose side However, these two main aspects are also considered in the EMC recommendations. Increase installed sensitive devices or systems

EMC, these two aspects can be implemented simultaneously, and with the application of this section recommended practices and standards such as IEC 60364 [3] series

Those related safety requirements are not contradictory. Because each facility is unique, designers and installers are responsible for specific facilities

Choose the most relevant recommendations.
