Because of rapid technological growth of electrotechnical industry and a high degree of obsolescence, human resource requirements are also becoming more specific and fast changing in this field. Technical inputs to these requirements, come from various disciplines like electrical engineering, electronics and telecommunication, physics etc. and manpower inputs from academic on the job experience and competence etc. Many times depending on the maturity of technology, a gap exists between the output of academic institutes and the input requirements of industry and society certified for this skill, competency and knowledge by a credible independent third party. Application and implementation of electromagnetic compatibility (EMC) concepts is a highly skilled and knowledge based activity. Since the effectiveness of any application of EMC techniques and tool depends upon the capabilities of the persons who performs a procedure needs to be developed to provide a means for evaluating and documenting the competence of personnel whose duties require the appropriate theoretical and practical knowledge of the EMC. In this paper the author has focused the need for skilled and specialized certified electromagnetic compatibility (EMC) professionals.

This experimental study aims at collection of conducted transient data on a power line (DC 28 volt) due to switching actions created by number of electrical and electronics loads in a combat tank. Power quality in a combat tank calls for strict adherence to MIL STD 1275A as number of sensitive electronic subsystems and large current devices are connected in the same bus. A number of transient data captured and recorded are analysed in the paper. Improvements carried out to power quantity by means of controlling the transients and redesign of the power bus are also addressed. Malfunction of sensitive electronic equipment on account of these transients are avoided totally. The concept of distributed power architecture is prescribed for minimum degradation in power quality.

In this paper, basic principles of fractals and their application for analysing EM radiation from lightning discharges in the atmosphere are discussed. Attention is drawn to how fractals have been used for geometric modelling of lightning to take care of tortuosity and branching. EM radiation can be computed from these models to obtain time and frequency domain information, which can be useful in estimating interference levels and setting up EMC standards.

Due to the ever increasing amount of modern equipment, electromagnetic pollution is increasing in a complex manner. In this pollution dominating world the entire human society is living in an electromagnetic environment. The effect of radiation on human beings is now playing a vital role, which may sometimes become fatal. The users and other inhabitants of the vast computer community and others where the chances of the electromagnetic environment existing, have become aware that serious questions are being raised about the potential harmful effects of the electromagnetic emission from display monitors and other such equipment. The magnetic field at ELF, VLF and non-ionizing radiation may cause biological effects and finally may lead to pressure, ulcer, high blood pressure, coronary heart problems and cancer. For magnetic field lines of force that readily penetrate almost anything including the human body, the existence of such a field can be visualized by proper EMC measurements. This paper is a study of the magnetic field produced by visual display units and the preventive measures to minimize the ill-effects.

The basic objectives of a good electrical grounding system are for human safety, reliability of equipment operation, fault current return and to limit EMI/transient over voltages coupling. After satisfying all the above requirements, the effect of corrosion on the grounding installation must be considered for sustaining effectiveness of grounding. In this paper various types of corrosion and prevention mechanisms and its importance in grounding are described.

Proposed allocations by the ITU in the Ku and Ka frequency bands for facilitating induction of non-GSO (non-geostationary orbit) systems using satellite constellations in low Earth orbit have raised a host of contentious issues. The problem of sharing of the radio frequency spectrum by non-GSO systems with the existing terrestrial and GSO satellite systems is complex. Any decision without a complete study is like to lead to the imposition of serious constraints and inequitable allocations. Sharing studies are in progress under the ITU Forum. A Joint Task Group set up on the directions of WRC-97 has concluded its examination of various issues. Due to shortage of time and resources the issues could not be resolved and need to be examined further for ensuring equitable sharing of the radio frequency spectrum. The unresolved issues are discussed.

Transient over-voltages caused by lightning, couples on to data communication or instrumentation signal lines and introduce serious fault alarm conditions and damage instrumentation electronics. Protection circuits to minimise the transient over-voltage are commercially available for variety of installation requirements. However, if an electronic system designer intend to build a protection circuit, a custom design will be desirable as the interface or inter-connection could be more effective for the intended environment. This paper brings out the various designs approach for a number of applications from radio communication antennas port to data acquisition signal lines. Also, the design details for a hybrid protection circuit is provided along with the results achieved.

The Bulk Cable Current Injection (BCCI) testing, at equipment/subsystems/system level has been recognised as a promising technique in lieu of radiated susceptibility testing upto few hundreds of MHz. Although it is an efficient technique for the evaluation of electromagnetic susceptibility (EMS) of the system, but at the same time due to its instrumentation particularly bulky and heavy current injection and monitoring probes, put a restriction to the use of BCCI, in the integrated system testing. In this paper, the use of BCCI test facility for integrated aircraft testing has been critically analysed and discussed. Problems which may arise due to the generation of strong harmonic products up to HF band in BCCI testing also have been discussed with their solutions.

Summary form only given. As per ANSI C 63.4-1992, a Radiated Emission Test Site (RETS) shall be considered acceptable for radiated electromagnetic field measurements if the measured Normalized Site Attenuation (NSA), are within +4 dB of the theoretical NSA for an ideal site for both horizontal and vertical polarizations. ANSI C 63.4-1992 allows +4 dB NSA tolerance, which includes antenna/instrumentation calibration errors, measurement technique errors, and errors due to site anomalies. These errors are analyzed in ANSI C 63.6-1988, wherein it is shown that more than 50% of the total allowable tolerance is contributed by the antenna factors of the transmit and receive antennas used and the performance of a well-built site contributes only 1 dB. Experience has shown that antenna factor variations may be caused by the antenna height variations and polarization changes with respect to the ground plane, the use of measurement geometries, mutual coupling, and transmission line scattering for vertically polarized antennas. Also, in ANSI C 63.4-1992, a single-point NSA measurement is carried out which is insufficient to pick up all possible reflections from the site very accurately. In this paper a new methodology is proposed called the "Comparison Method", in which the uncertainty in antenna factors used for SA measurements is avoided. In this approach, instead of a comparison of measured with theoretical "NSA" as given in ANSI C 63.4-1992, the RETS is validated by comparing the SA's measured at different locations without changing the antenna path geometry, because only one reflecting surface (metal ground plane) exists.
只提供摘要形式。根据ANSI C 63.4-1992,如果测量的归一化站点衰减(NSA)在水平和垂直极化的理想站点的理论NSA的+4 dB范围内,则辐射发射测试站点(RETS)应被认为是可接受的辐射电磁场测量。ANSI C 63.4-1992允许+ 4db NSA公差,其中包括天线/仪器校准误差,测量技术误差和由于站点异常引起的误差。这些误差在ANSI C 63.6-1988中进行了分析,其中表明,所使用的发射和接收天线的天线因素贡献了总允许公差的50%以上,而精心构建的站点的性能仅贡献了1db。经验表明,天线因子的变化可能是由天线高度的变化和相对于地平面的极化变化、测量几何形状的使用、相互耦合和垂直极化天线的传输线散射引起的。此外,在ANSI C 63.4-1992中,进行了单点NSA测量,这不足以非常准确地从站点拾取所有可能的反射。本文提出了一种称为“比较法”的新方法,该方法避免了用于SA测量的天线因素的不确定性。在这种方法中,与ANSI C 63.4-1992中给出的测量与理论“NSA”的比较不同,RETS通过比较在不同位置测量的SA来验证,而不改变天线路径几何形状,因为只有一个反射面(金属接平面)存在。
