| Summary: | To control the levels of electric fields, electric field
strength sensors are required. Currently, for these purposes, the most promising are dual electric induction
sensors, which are a constructive combination of two
double sensors into one whole. There are two types of
dual sensors with overhead, composite and separate
sensing elements. The output signals of such sensors
are electrical parameters such as charge, current and
voltage. Studies have shown that electrical charge has
the greatest advantage. To remove the charge from the
sensor, it is recommended to use a current integrator
(charge amplifier) as the primary measuring circuit.
Secondary measuring circuits of the dual sensors
considered in this work are used for averaging the
signals of double sensors in order to reduce the error
from the inhomogeneity of the electric field and form
an output signal proportional to the field strength. It
has been established in the work that sensors with
overhead and composite sensitive elements allow to
perceive the intensity of an inhomogeneous electric
field with an error not exceeding +4,6 % in the spatial
measurement range 0a1. The work also determined
the sensitivities of two types of dual sensors of the
electric field strength. |
