The article presents previously unpublished results of the development of current sensors, designed on the basis of cold-cast possibilities of magnetic materials and their applications for measurement purposes in the field of electricity and power electronics. Listed are the fundamental characteristics of the magnetic alloy resin schematic draft sensor dI/dt of a core of magnetic material molded and the measurement results of the prototype produced industrially.

Classrooms, lecture, lecture, conference and convention halls can be considered as spaces in which there is sometimes one way, but more often two-way communication through the transmission channel. Equally important is the transfer of key information in voice alarm system.

The article presents the results of unpublished research on the new generation current sensors, designed on the basis of cold-cast magnetic materials. The development of current sensors with core cast focused primarily on the possibility of their application for the measurement of large currents and for the purpose of measuring the electricity and power electronics. The article presents the results of measurements of transmission characteristics of the prototype sensor, the sensing ampli­fier design and measurement results of the entire scanning unit.

The transmission channel mediates the flow of information (information transfer) between the source and the information received. In terms of examining the technical characteristics of the transmission channel is probably the most widely used model Shannon-Weaver model of communication, in-processes to technical blocks. From the perspective of media communications and generally assess the overall effect of the transmission of information via Lasswell communication model.
