About This Item
C37.90.2-2024 defines radiated electromagnetic interference withstand capability requirements and tests for power, energy, and industry applications. In practical terms, it helps engineers evaluate whether equipment can continue to operate as intended when exposed to radiated electromagnetic interference. This makes C37.90.2-2024 important for design verification, product qualification, and compliance-focused testing where electromagnetic compatibility and disturbance immunity are relevant to field performance.
About C37.90.2-2024
This technical document focuses on withstand capability against radiated electromagnetic interference, with test requirements aimed at confirming that equipment can tolerate external electromagnetic energy without unacceptable degradation. It is most relevant where electrical and electronic systems must remain dependable in demanding operating environments. C37.90.2-2024 is therefore useful as a reference for defining test methods, assessing immunity-related performance, and supporting consistent engineering decisions during development and acceptance activities.
Where is C37.90.2-2024 used?
C37.90.2-2024 is commonly used for equipment in power, energy, and industrial settings where radiated interference may affect control, monitoring, or protection functions. It may apply to devices installed in substations, utility automation systems, industrial control panels, and related electrical apparatus. The standard is particularly relevant when testing products that must operate reliably near switching equipment, communication systems, or other sources of electromagnetic disturbance.
Importance in practice
In practice, C37.90.2-2024 supports more consistent compliance testing and clearer acceptance criteria for interference withstand capability. It helps reduce the risk of unexpected behavior caused by radiated electromagnetic exposure, which can affect performance, availability, or operational confidence. For manufacturers, specifiers, and test labs, the standard can improve design control and procurement decisions by providing a defined technical basis for verification. C37.90.2-2024 also helps align test results with real-world operating expectations.
