A distributed system of protection and diagnostics of support structural elements of high-voltage power lines (HVPL) on 500 kV voltage was developed at Karaganda State technical university: -current monitoring of leakage currents of bunches of suspension insulators; -detection ice-rime depositions; -cathode protection of underground elements of support constructions; -information transfer from the sensors placed on supports on the control office on telemetric channels; -creation of the passport of each support on SCADA -system basis.The system contains set of local subsystems of protection, measurement, processing and information transfer on support, communication links and a subsystem processing and information storage on the control offices. Power supply of local subsystems is provided by the directed energy of electromagnetic fields. Detection of ice-rime deposits is carried out by the indirect methods based on the current monitoring of the support response of wind and ice loads and also temperatures and air humidity. Sensors information allows to control integral values of a leakage current of industrial frequency and surface currents of the partial discharges proceeding through strings of insulators and also to define the time-point optimum for drop-out ice-rime deposits. Radio modem and cellular communication with an automatic choice of the communication channels in the conditions of the powerful electromagnetic fields have a significant effect on an opportunity and transmission quality of information are used for transmission the telemetric information to the control office. Tests with the positive results of the experimental samples of all components of system are carried out on the operating line and in laboratories. The developed system is a basis for methods creation and technical solutions on lowering the losses of the electric power in case of its transportation on 110 and 220 kV HVPL.

Currently, Kazakhstan and CIS countries no system diagnostics and protection elements of high-voltage power lines on the basis of local automation systems. At the same time a great need for cathodic protection systems of support elements, the system control leakage suspension insulators, sleet and snow build-up of deposits. The main obstacle to the establishment of such systems is the lack of energy sources. This paper is designed layout receivers electrostatic converters. Based on the developed equivalent circuits created a simulation model for the magnetic component of a resonant circuit.
