GTL-845 mikrobilgisayar tabanlı Hat İzleme ve Koruma rölesi

GTL-845 Micro-computer Based Line Monitoring Protection Device, which is a digital protection unit for current and voltage protection, is mainly used in the industrial and mining enterprises and small current neutral grounding power systems of civil architecture in 10kV and below. It is a main and back up protection of vatieties of electical equipment and wires. GTL-845 use microprocessor and digital processing technology to give main and back up protection, aiming to replace traditional electromagnetic relay to achieve digital and intelligentized protection.

Charactristic

A. 4U standard aluminum chassis, combination of plug-in structure, after the plug case, each functional module design alone, electricity are completely separated, strong anti-interference ability, convenient field maintenance;
