This paper describes the distribution of surge currents inside a building during a direct lightning strike, on the basis of numerical simulations of building wiring, various loads, and five different combinations of metal oxide varistors connected inside the building as surge arresters and suppressors. The 10/350 ps wave with a peak current of 20 kA, which is widely accepted as a simulation of current in a direct lightning strokes, is used as the source. The network inside a building is modeled as eight branch circuits, each with a different resistive, capacitive, or inductive load and each with a different length. The results of this modeling is compared with the 8/20 and 10/1000 ps standard surge test waveforms. It is shown that the surge test waveforms in ANSIDEEE C62.41 have a peak current and duration that are both too small to represent the effects of a direct lightning strike to the mains. Instead of revising 052.41 to include larger stresses for the environment inside a building, it is urged that standards specify maximum allowable values of peak surge current and rate-of-change of current inside a building. Coordinated surge arresters and suppressors should be used to keep surge currents inside a building within the specified limits.

An electromagnetic interactions modelling tool which is based on a fuzzy logic representation of the electromagnetic attributes in a topological decomposition of a system is described. The purpose of this tool is to help determine any electromagnetic compatibility problems in complex systems. This tool is an extension of the HardSyslHardDraw software [l, 21 enabling it to handle a fuzzy representation of the electromagnetic interaction data. HardSys, a prototype system implemented in Prolog, is weld to propagate the electromagnetic information through the topology of the represented system. User interaction is through HardDraw, ,an electromagnetic topology drawing tool and an attribute interface. Introduction The adverse effects of electromagnetic interactions in electrical systems are of concern because of the increased pollution of the environment with electromagnetic emissions and because of the increasing susceptibility of system components. From a practical point of view, it is not a simple matter to ensure {he electromagnetic integrity of systems even for relatively small interaction problems. Non-algorithmic or heuristic techniques are used daily by engineers to solve electromagnetic problems in electrical systems. An attempt to formalize these procedures in the form of a computer tool called HardSys/HardDraw was described in [l, 21. The modification of the knowledge representation used in this prototype tool into a fuzzy form [3] is described, This allows the heuristics and uncertain information associated with an interaction problem to be modelled more realistically than was possible in the first version of the tool.

The volumes define the electromagnetic components involved in the interaction. The interaction sequence diagram keeps track of the interaction paths throughout the system.

描述了一种基于系统拓扑分解中电磁属性的模糊逻辑表示的电磁相互作用建模工具。该工具的目的是帮助确定复杂系统中的任何电磁兼容性问题。该工具是HardSyslHardDraw软件的扩展[1,21]，使其能够处理电磁交互数据的模糊表示。HardSys是一个用Prolog实现的原型系统，用于通过所表示系统的拓扑传播电磁信息。用户交互是通过HardDraw电磁式拓扑绘制工具和属性接口实现的。由于电磁辐射对环境的污染增加以及系统组件的易感性增加，电气系统中电磁相互作用的不利影响受到关注。从实际的角度来看，即使是相对较小的相互作用问题，要保证系统的电磁完整性也不是一件简单的事情。工程师每天都使用非算法或启发式技术来解决电气系统中的电磁问题。在[1,21]中描述了以称为HardSys/HardDraw的计算机工具的形式将这些过程形式化的尝试。本文描述了将原型工具中使用的知识表示修改为模糊形式[3]，这使得与交互问题相关的启发式和不确定信息能够比工具的第一个版本更真实地建模。通过将电气系统分解为相应的电磁屏蔽拓扑及其对偶图或相互作用序列图，可以隔离电气系统的电磁相关属性[4,5,61]。电磁拓扑由电磁区分体及其相关表面的描述组成。这些体积定义了相互作用中涉及的电磁分量。交互序列图跟踪整个系统的交互路径。相互作用序列图可以简单地从给定的电磁拓扑中推导出来。表示计算机简化拓扑的图形如图1所示。请注意字段节点、电路节点和交互路径节点的不同节点表示[1,2]。William H.

The response of 15 aircraft antennae to fast risetime EIW (FREMP) was determined by experimentally measuring their response to a surface electric field in the frequency domain, transforming the response into the time domain and convolving the result with the Bell Laboratories double exponential and a full amplitude step function. The step response could be 3 to 5 times as high as the double exponential response. Analysis of the measured antenna responses with respect to their physical dimensions showed that a reasonably good estimate of the antenna's transfer function could be obtained from its overall physical dimensions.
