DIMAT's highly secure analog teleprotection terminal is designed to be used with any analog transmission channel such as PowerLine Carrier links over high-voltage lines, telephone cables, radio links...
The technology is based on digital signal processing (for the generation and detection of the signals) and microprocessors (for control and decision tasks). The use of a non-linear process for the reception of command tones enables TPC-2 terminals to keep these signals independent from the line noise, providing extremely high levels of security. It is designed and developed according to the IEC 60834-1 Recommendation for teleprotection systems.
TPC-2 terminals can be equipped to transmit and receive two or four commands. These commands can be used for blocking, permissive and direct tripping teleprotection schemes, achieving in each case an optimal combination of security, dependability and transmission time.
TPC-2 terminals register all alarms and events produced in the teleprotection link. To establish the date and time at which the alarms and/or events are produced, TPC-2 terminals have a real-time clock with the possibility of GPS synchronization by means of an IRIG-B interface.
