PLANT FOR INVESTIGATION OF STATIONARY ELECTRIC FIELD Russian patent published in 2013 - IPC G09B23/18 

FIELD: electricity.

SUBSTANCE: plant comprises: a switch for two positions for connection to a voltmeter with high input resistance or a single probe, or a double probe with a pointer, a set of detachable various pairs of conducting buses, which model various flat electric fields; screws with nuts installed on a pad with electroconductive paper for fixation of a pair of detachable conductive buses; a central screw with a nut, installed on a pad with electroconductive paper in the middle between the pair of detachable conductive buses; a template from a dielectric with a working edge corresponding to the profile of the bypass contour, fixed on the pad with electroconductive paper with the help of the central screw with the nut; a set of detachable various templates from dielectric, which model various bypass contours. A movable ruler with one end is fixed on a runner moving along a fixed stem in parallel with an axis Y, and its second side lies on the fixed ruler. Besides, the plant comprises a pad with a document sheet and a system of coordinates similar to the one installed on the pad with electroconductive paper.

EFFECT: increased accuracy of performed experiments.
