Electromagnetic compatibility design of power field service terminal

In this paper, many kinds of electromagnetic interference radiation sources of power field service terminal are analyzed. When each module of terminal is designed, electromagnetic compatibility is considered, requirements of test standards and the experience of practical solutions in the course of electro magnetic compatibility (EMC) design, some effective methods to restrain electro magnetic interference (EMI), such as surge, electrical fast transient burst and electro static discharge (ESD), are discussed in detail, combined the testing results. The results show that the design and anti-interference measures presented are easy and effective. Electromagnetic compatibility of terminal is improved overall.
