Belong to plate and the second metallic plate is arranged in parallel and loads burning voltage respectively and generates the device of uniform electric field to electric-field sensor progress
Calibration.In test process is demarcated, sensor is placed in caliberating device center plane location, to the first metallic plate and the second metal
Plate applies voltage V respectively0+With voltage V0, the spacing of two-plate is d0, at this time the theoretical electric field level in device be
Fig. 2 is the electric field distribution curve of Fig. 1.As shown in Fig. 2, it is nothing that the precondition of above formula, which is two metal polar plate sizes,
Limit is big, in actual caliberating device, since metal polar plate is finite size, and under the action of edge effect, point of electric field
Cloth is not uniform.Nearer apart from edge on central plane, electric field error is bigger.It can also be seen that electric field from curve
Can only be kept in the region of near center location very little relatively flat with it is consistent.So to ensure during the test, every
When applying equal voltage in secondary test, electric-field sensor present position electric field is consistent, it is necessary to which electric-field sensor is placed on
Center, to avoid the influence of edge effect.It therefore,, every time can only be due to the limitation of field uniformity every time in test
Central office portion place sensors.This is also resulted in high-volume electric-field sensor test process, can only often be surveyed every time
