Put simply, Teleprotection systems monitor transmission line conditions and coordinate tripping to quickly isolate faults.
Dewar have over 40 years’ experience in designing and manufacturing Teleprotection equipment in Australia. Their Teleprotection terminals have been the industry standard for over 30 years throughout Australia and New Zealand.
Dewar provide a 3U full Teleprotection unit with options of G703, VF or C37.94 compatibility and the new slimline version 1U full Teleprotection unit providing C37.94 compatibility.
The DM760 – Simple, speedy conversion of G.703 to C37.94 over long distances.
The DM760 Fibre converter, G.703 to C37.94 is intended for connecting Teleprotection equipment to multiplexers at substations.
The unit directly connects protection equipment and/or multiplexers, or microwave links to use C37.94 to interconnect with equipment that only supports G.703 interfaces.
