About This Item
IEEE C37.90.2-1995 is a technical standard for the withstand capability of relay systems exposed to radiated electromagnetic interference from transceivers. It is relevant where protective and control relays may be affected by nearby radio-frequency emissions, helping define how these systems should respond under interference conditions. For engineers and buyers working with power, energy, and industrial applications, the document supports more consistent testing, design decisions, and acceptance criteria for electromagnetic compatibility.
What is IEEE C37.90.2-1995?
This standard addresses how relay systems are expected to withstand radiated electromagnetic interference produced by transceivers. In practice, IEEE C37.90.2-1995 provides a focused reference for evaluating susceptibility in relay equipment used in electrically active environments. It is part of the broader technical context of fields, waves, and electromagnetics, but its application is specifically tied to power-system relays and related control functions. The standard helps define a common basis for laboratory testing and performance assessment.
Where is IEEE C37.90.2-1995 used?
IEEE C37.90.2-1995 is commonly used around relay systems in substations, switchgear, protection panels, and other power-system control installations. It is especially relevant where transceivers or radio equipment may operate near protective relays and could introduce radiated interference. The standard may also be referenced during equipment qualification, procurement review, and EMC testing for utility and industrial power applications. It supports engineering teams that need predictable relay behavior in RF-exposed environments.
Why is IEEE C37.90.2-1995 important?
The value of IEEE C37.90.2-1995 is in reducing uncertainty when relay systems are exposed to radiated electromagnetic energy. By using a defined withstand reference, organizations can better compare equipment performance, support compliance reviews, and lower the risk of unwanted relay operation or missed operation. For procurement and design teams, the standard also improves consistency in test expectations and helps align equipment selection with the electromagnetic conditions present in power and industry installations.
