Space charge measurements: electrode effects and prebreakdown

[1992] Proceedings of the 4th International Conference on Conduction and Breakdown in Solid Dielectrics, 2003
The authors discuss the measurement of space charge in insulating polymers using a nondestructive method called the thermal step method (TSM). The principles of the TSM are first described. Using this method, the authors study the influence of semiconducting electrodes which assure the electric contact between the insulating polymers and metal ...

Space charge measurement by a simple induction method

Measurement Science and Technology, 1990
An induction method for space charge measurement is compared with the usual current measuring method. Its working principle is straightforward and no protective measure has to be taken to safeguard the measuring equipment. The device has been calibrated both theoretically and by an electrolytic tank method.

LIPP and PEA space-charge measurements on LDPE

Proceedings of 1995 IEEE 5th International Conference on Conduction and Breakdown in Solid Dielectrics, 2002
Several methods of measuring directly the spatial distribution of space-charge in an insulator have been developed during the last decade, e.g. laser induced pressure pulse (LIPP), piezo-electrically induced pressure step (PIPS), pulsed electroacoustic (PEA), thermal pulse (TP), thermal pulse step (TSP) and laser induced modulation (LIMM).

Measuring the Net Charge Density of Space Plasmas

2023
Space plasmas are composed of charged particles that play a key role in electromagnetic dynamics. However, to date, there has been no direct measurement of the distribution of such charges in space. In this study, three schemes for measuring charge densities in space are presented.

Electric Space Charge and Potential Gradient Measurements

Nature Physical Science, 1971
THE two most widely used methods for the measurement of space charge in the lower atmosphere involve either filtration of the air and direct measurement of any charge trapped by the filter, or measurement of potential gradient in the atmosphere at different levels and use of Poisson's equation to obtain values of the space charge1.
