Advantages over analogues: Принцип совместной передачи и приема сигналов высокочастотных защит и дискретных команд, использующий частотное кодирование с частотной манипуляцией, защищен патентом РФ на изобретение. Используется отдельная полоса частот для передачи сигналов в каждом направлении. Расположение полос смежное, каждая шириной 2 кГц, результирующая ширина полосы для 2-х концевых линий 4 кГц, для 3-х концевых - 8 кГц. Постоянный контроль текущего запаса по затуханию на приеме. Возможность компенсации времени распространения сигнала по линии в режиме ДФЗ для устранения асимметрии фазной характеристики. Возможность установки стабильной величины перекрытия импульсов в режиме ДФЗ во всем диапазоне входного напряжения манипуляции. Full symmetry of the pulse rise and decay at the reception on their transmitters and remote mode DFZ.

The development stage readiness: Introduced in production

Description of the development:
()
The functionality of the transceiver AVANT RZSK: Transmission and reception of signals and commands relay protection (RP) for 2-D and 3-terminal lines. Signaling defenses and commands can be performed either separately or simultaneously. The transmission of up to 4 teams in each side of the channel. Can be used as a transceiver signals only defense or only teams. In the latter case can be transferred to the 8 teams in each direction. Interfaces, RF parameters, EMC and immunity in the transmission of commands RH comply with all existing requirements for HF communications equipment for the RE and PA. There are half-duplex intercom between the ends of the protected line during the RF channel setting. AVANT RZSK can work together with all kinds of existing protective relays, made to: Electromechanical relays. Semiconductor element base. Microprocessor-based terminals. Examples of use Signaling RF protection. The transfer of commands and RH PA (UPASK). Authorizing the transfer of command of the current backup protection in addition to directional signals of the main protection. Additional use of the main channel of protection for the emergency control transfer instructions (SAON, breaker, ALARA, AR, ACHR, etc.). Reservation of the major defenses to double circuit transmission lines to allow cross-signals (commands) on parallel channels. Duplication of the RE teams passed through the UPASK. At the 3-terminal lines with the installation of security at all or only at the two ends, and signaling transfer trip to otpaechnoy substation and at her. Certificate of Federal Agency on Technical Regulating and Metrology for compliance with Transceiver signals and commands RH AVANT RZSK (serial production) with the requirements of normative documents ROSS RU.AYA55.N06194 number 0175749.
