The global mains power supply is divided into two major voltage systems: 220~240V/50Hz is the mainstream, covering China (single-phase 220V, three-phase 380V), Europe (single-phase 230V, three-phase 400V), the United Kingdom (240V/415V), Australia and New Zealand, Southeast Asia and African. Electrical engineering is governed by a comprehensive framework of standards that ensure safety, efficiency, and interoperability across various systems and devices. These standards are established by international bodies and national organizations in major countries, each contributing to the. The International Electrotechnical Commission (IEC) is the leading global organization that prepares and publishes International Standards for all electrical, electronic and related technologies.
