IEC 61936-1: Power Installations Exceeding 1 kV AC and 1.5 kV DC – Part 1: AC

  1. Design and Planning: The standard requires that high-voltage electrical installations be designed and planned with safety, reliability, and efficiency in mind.
  2. Safety Precautions: The standard specifies safety precautions that must be taken during the installation, maintenance, and operation of high-voltage electrical systems.
  3. Electrical Equipment: The standard sets out requirements for the selection, installation, and testing of electrical equipment, including high-voltage switchgear, transformers, and cables.
  4. Insulation Coordination: The standard requires that insulation coordination be considered in the design and installation of high-voltage electrical systems to ensure that the system can withstand electrical stresses.
  5. Testing and Commissioning: The standard specifies testing and commissioning requirements for high-voltage electrical installations to ensure that they are safe and functional.
