摘要

In general, the effectiveness of in-line devices for protection of electric initiators from radio frequency electromagnetic hazards depends upon absolute parameters of the loaded devices plus parameters of the external electrical circuits. The absolute parameter 'minimum insertion loss' has been defined and its determination has been derived. This parameter is independent of generator source impedance. Definitions and methods of measurement of transfer functions and impedances required for its calculation are described. The application of each of the device parameters to assist in making a choice among available protective devices is described, and examples of use of the parameters are given, illustrating the direct comparison of protective devices for worst-case application. Appendix I contains a derivation of an exact solution for the critical source impedance which produces minimum insertion loss for a given loaded protective device at a given frequency. Appendix II contains a description of a simple graphical method for determining minimum insertion loss. (Author)
