Introduction: What is IEC 255-22-2?
This document is an international standard that specifies how to test electrical protection equipment against static electricity.
The official title of the standard, IEC 255-22-2, can be broken down into its key components to understand its focus:
- IEC 255-22-2: The standard’s official number.
- Electrical relays: The general category of equipment it covers.
- Part 22: Electrical disturbance tests for measuring relays and protection equipment: The specific series of tests it belongs to, focusing on how devices handle electrical interference.
- Section 2: Electrostatic discharge tests: The exact type of disturbance this document details.
The core objective of this standard is to confirm that the equipment being tested will not malfunction when it is energized and subjected to an electrostatic discharge.
