Bpl telecom offers the entire range of power line carrier communication equipment products designed & manufactured for power utility communication networks. As a part of tele-protection equipment transmits the trip signal from the protection equipment in power station and substations. Tele-protection links using power line carrier channels are the most economical way of performing all the tasks associated with transmitting tripping signals. Security, dependability and transmission time are the important characteristics of any tele-protection equipment. Interface on the communication channels should neither be interpreted as a trip command [security] nor in admissibly delay the transmission of genuine trip commands. Salient features are as follows:
1. available up to 4 commands
2. signal boosting for reliable transmission of every trip signal
3. no additional bandwidth required.
4. test facilities: local test, end to end test, loop test.
5. lcd based trip counters to indicated no of trips transmitted / received.
6. visual indications provided through leds to indicate presence of trip & guard frequencies.
7. audible alarm is provided to indicate system is in test mode.
8. test mode: actual test trip can be simulated.
