What is IEC 62271-202?

IEC 62271-202, also known as High-voltage switchgear and controlgear – Part 202: High-voltage/low-voltage prefabricated substations, is a technical standard developed by the International Electrotechnical Commission (IEC). It provides guidelines and requirements for high-voltage switchgear and controlgear assemblies that are pre-assembled in a factory environment.

The Purpose of IEC 62271-202

The main purpose of IEC 62271-202 is to ensure the safety and reliability of high-voltage electrical systems. By setting clear guidelines for the design, production, and testing of prefabricated substations, this standard aims to enhance the performance and efficiency of electrical infrastructure.

Key Requirements of IEC 62271-202

IEC 62271-202 outlines several key requirements that prefabricated substations must meet to comply with the standard. These include:

Mechanical Strength: The equipment should be able to withstand mechanical stresses during transportation, installation, and operation.

Electrical Safety: The substation must provide adequate protection against electric shocks, short circuits, and other electrical hazards.

Environmental Conditions: The equipment should be designed to operate effectively in various environmental conditions, including extreme temperatures, humidity, and corrosive environments.

Functional Reliability: Prefabricated substations should be able to perform their intended functions reliably, with minimal risk of failure or malfunction.

Interchangeability: The components used in the assembly should be easily replaceable to simplify maintenance and avoid prolonged downtime.
