摘要：

A device is described which is capable of measuring the charge density carried by an insulating fluid. The monitor relies on the principle of charge relaxation in two tandem chambers in such a way that the measurement is independent of residence and relaxation times. It is robust, has no moving parts, and is also able to monitor the conductivity of the fluid in applications for monitoring the streaming electrification in power transformers. Performance, accuracy and applications are outlined. © 1990 IEEE
