The IEC 61936-1:2021 link refers to the connection between the standard and its applications in the electrical industry. The standard is widely adopted by electrical power system operators, owners, and designers, who use it to ensure that their power installations meet the necessary safety and performance standards.
| Voltage (kV) | Min. phase-to-earth clearance (indoor, standard atmosphere) | |--------------|-------------------------------------------------------------| | 12 | 120 mm | | 24 | 180 mm | | 36 | 250 mm | | 52 | 360 mm | | 145 | 1.0 m (approx.) | Whether you are a power system engineer, a
The electrical power installation, as defined by the standard, includes, but is not limited to, the following equipment [6†L6-L9, 12†L18-L27]:
The standard continues to evolve. The ISO Central Secretariat has reported a CENELEC amendment, , intended to clarify and adapt requirements for power installations exceeding 1 kV AC and 1.5 kV DC. This highlights that the standard is a living document, with national and regional bodies issuing amendments to address specific concerns or local regulatory requirements.
