| description | The purpose of the study is to review the existing devices
and methods for diagnosing and monitoring the state of
high-voltage insulation, which plays an important role in
the criteria for the reliability of the power system. One
of the main methods for diagnosing insulators is a visual
inspection. At the moment, online methods have become
widespread, allowing to fix the process of destruction of
insulation under voltage. Despite the existence of various
methods and devices, the problem of timely detection of
insulation deterioration in the operating mode has not been
solved at the moment. This problem is solved by using
an additional shunt design. When the task is achieved,
the method of calculating the strength analysis of the
additional shunt is used, and the simulation of this process
is performed in the ANSYS program. Mechanical strength
sufficient for operation under voltage. Experimental tests
are carried out with the developed sample of the shunt. As
a result of the study, a number of experiments are carried
out with this design of the shunt, which have confirmed
its performance. Due to the presence of the shunt, it is
possible to fix leakage currents of the order of several tens of microamperes. Thus, the authors have proposed the
current sensor, which is made in the form of an additional
resistive shunt. |
