EMC evaluation of a new induction equipment. A case study

With the growing density of electrical and electronic systems onboard contemporary naval platforms, electromagnetic interference and compatibility aspects have acquired matters of great significance. A large number of equipment, emitting signals over a wide range of the electromagnetic spectrum, have to co-exist with sensitive surveillance systems covering the very same spectrum onboard a warship with limited real estate area. Further, in the process of continuous upgrading and modernisation of a warship required to keep abreast with emerging technologies, state of the art equipment are installed from time to time to augment/retrofit existing systems in the already dense EM environment onboard. This paper discusses the salient aspects of the evaluation process adopted for induction evaluation of new electrical/electronic equipment from the EMI/EMC point of view. A case study for evaluation of a new generation high power HF (1.5-30 MHz) transmitter has been illustrated to highlight the various inter-linked aspects in the evaluation process.
