EQUIPMENT FOR TELEPHONY, TELEMECHANICS, DATA TRANSMISSION, DISCRETE SIGNALS OF RELAY PROTECTION AND EMERGENCY CONTROL COMMANDS.

Digital equipment AKST RZPA "Line-C" - for organisation of HF channels of PM, TF, TM, PD, RZ and PA on power lines 35-1150 kV in information structures of TM, ASCUE, RZA, PA, dispatching and technological control of power systems. Built-in/removed in a separate device block of transmission/reception of RZPA commands.Communication with the remote terminal via OK; operation of the RZPA channel on 3 and 4 end lines; Euroconstruct 19", 6U; flexible configuration; high speed and multi-channel data transmission.Built-in protocol converter 101/104; modems with a special algorithm to eliminate information loss when adapting the speed. Stable work at noise bursts (up to 1s), and fast recovery (1-4s); power allocation per channel PD with a band from 5 to 12kHz on the principle of "1 modem - 1 channel"; flexible possibilities of frequency compaction; continuous monitoring of the characteristics of equipment and channels with the display in the form of graphs; recording oscillograms of RF input; log of user actions
