A Technique for Measuring Effective RFI Radiated from Electrical and Electronic Equipment
1967 IEEE Electromagnetic Compatibility Symposium Record, 1967A method of measuring the "effective" radio frequency interference radiated from electrical and electronic equipment is under investigation. The method* employs measurement of current in the power supply or ground leads of the interference source. It has been highly developed in France, but is little known in the United States.

Equipment and techniques for the measurement of radar reflections from model targets
WESCON/57 Conference Record, 2005One of the most important factors in radar system design is the radar cross section, or echo-area, of the target. To eliminate some of the difficulties of measuring this quantity with actual aircraft and radars, scale model techniques have been developed which permit a high degree of flexibility and accuracy in the determination of radar reflection ...

Measurement technique for EMC evaluation of military communications-electronics equipment
IEEE 1988 International Symposium on Electromagnetic Compatibility, 2003An integrated test methodology to evaluate command, control, communications, and intelligence (C/sup 3/I) systems in a combat electromagnetic environment is presented. The methodology allows the US Army to test and field major C/sup 3/I systems in less time, and with greater confidence in successful operation, than was previously possible. Modeling and

Improvement of measurement techniques in PD pulse detection in large HV equipment
Seventh International Conference on Dielectric Materials, Measurements and Applications, 1996Partial discharge (PD) measurement has been used as a tool to assess insulation integrity for many years. In terms of detection of PD pulses, a proper assessment of insulation integrity relies on accurate acquisition of the PD pulse signal. However, measurement errors may arise due to the measurement facilities involved. This paper discusses one aspect

Partial discharge. VII. Practical techniques for measuring PD in operating equipment
IEEE Electrical Insulation Magazine, 1991For pt.VI see ibid., vol.7, no.3, p.9 (1991) Online partial-discharge (PD) tests for monitoring the condition of the solid dielectric insulation in high-voltage equipment are discussed. Sources of external electrical noise are identified, as are attributes of PD and noise that are helpful in drawing distinctions between them. Methods for distinguishing
