Description

The registrar of arc short circuits of DOUG-au is intended for work together with the fiber-optical sensors (FOS). The registrar can be used in arc protection of distributing devices without DUGA-BTs-150 blocks, influencing digital devices of relay protection and automatic equipment (TsRZA).

The registrar of arc short circuits of DOUG-au provides transformation, transfer, storing and display of signals from fiber-optical sensors at emergence of arc short circuit, and also definition of the place of emergence of arc short circuit to within a compartment.

The registrar of arc short circuits of DOUG-au is intended for installation in cells on voltage of 0,4-35 kV, including on objects of nuclear power.

Overall dimensions of the registrar of arc short circuits DOUG-au - 115х116х61,7 mm (SHKHVKHG), weight unpacked - no more than 0,67 kg.
