Partial discharge. VII. Practical techniques for measuring PD in operating equipment

IEEE Electrical Insulation Magazine, 1991
For 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

Internal Loss Measurement Technique for Optical Devices Equipped with Fiber Connectors at Both Ends

Applied Optics, 1995
This paper describes a convenient technique for measuring the loss of optical devices that have connectors at both ends. The technique can provide both bidirectional internal and values temporal connector loss by the mathematical solution of four normalized power measurements. Accuracy of the internal loss measurement is limited by the need to use four

Measurements in opera houses: comparison between different techniques and equipment

1998
In room acoustics many objective parameters to quantify subjective impressions have been introduced. These quantities can be measured by using a wide variety of powerful tools and equipment. The results can be influenced by the measurement techniques and instruments used.

Noise-rejection techniques for impedance and dielectric spectrometers using ubiquitous test and measurement equipment

Review of Scientific Instruments, 2007
This work encompassed the development for a frequency-domain impedance and dielectric spectrometer using ubiquitous test and measurement equipment, i.e., signal generators and digital oscilloscopes. Various methods of amplification, noise rejection, and computations were employed to achieve the desired goals.

New equipment and new technique for measuring activity coefficients and Henry's constants at infinite dilution

Review of Scientific Instruments, 2011
New equipment is presented along with various experimental procedures and setups to cover a large range of applications. It represents a considerable improvement in terms of speed, accuracy, and simplicity with respect to classical gas stripping methods known as “dilutor techniques.” Furthermore, range of conditions of its use is larger in terms of ...
