| Summary: | Measurement and control of the intensity levels of
inhomogeneous electric fields with high accuracy is quite
a difficult task. The solution to this problem is connected
both with the development of new sensors and methods
for measuring the electric field strength. The creation
of new high-precision electrical induction sensors has
exhausted its capabilities at the current level of technology
and technology. Therefore, new ideas are needed for
solving the problems of high-precision measurement
of the electric field strength. One of these ways is the
development of new measurement methods. Existing
measurement methods characterized by the complexity
of the measurement processes, suitability in some cases,
and unsuitability in others, do not provide the desired
metrological characteristics. Therefore, the work related
to the development of methods for measuring the intensity
of inhomogeneous electric fields does not stand still, and
is relevant. The aim of the study is to create a new method
for measuring the strength of electric fields using known
sensors, which makes it possible to significantly reduce the error in measuring inhomogeneous electric fields.
The idea of constructing a new measurement method is
formed. The idea of the method is that in the presence
of two physical quantities measured with different sign
values of the error, the average value of the physical
quantity will always be closer to the true value. Based
on this, a new method for measuring the intensity of
inhomogeneous electric fields is proposed, associated only
with the original measurement process. The measurement
method id named «Average value method» (MSZ). The
estimation of the error of this method shows a decrease
in the measurement error to +5 % with the full spatial
measurement range 0a1. Using the «Average value
method» it is possible to achieve a significant increase in
the accuracy of measuring the strength of inhomogeneous
electric fields in a wide spatial range of measurements in
comparison with known methods. |
