METHOD FOR MEASURING OF DIELECTRIC PENETRABILITY OF LIQUID AND FLAT SOLID DIELECTRICS

摘要

FIELD: the invention refers to measuring technique. ^ SUBSTANCE: the method for measuring of relative dielectric penetrability of liquid and flat solid dielectrics is based on application of reactive resistance of flat air condenser in the result of filling its clearance with investigated dielectric. Alternate electrical voltage is applied to the electrodes of the flat air condenser with a regulated clearance equal to the thickness of the sample. The condenser current is converted into voltage for example with the aid of an operative amplifier, this voltage is regulate to receive its value numerically equal or multiple to dielectric penetrability of air. The sample is placed tightly between the electrodes of the condenser and the value of relative dielectric penetrability is determined on the indexes of a registering device for example of a voltmeter. ^ EFFECT: this method for measuring is sufficiently simple and accurate. ^ 1 dwg
