The Study of the Disturbance From Working Frequency and the Grounding in Electronic Measuring System
JI Yi-fei · 2004
Disturbing Voltage is estimated equivalently according to the measurement of the typical numerical values between the leakage voltage and leakage resistance from the equipment of the oscillograph and the millivoltmeter based on the working frequency disturbance model.It manifests the common-ground necessity of the equipment among the electronic measuring system.In addition,the applicable examples are introduced with the usage of common-ground link and AC bridge.
