Topscomm transmission distribution fault indicator consists of two parts, namely, the Acquisition Unit and Collection Unit.

Acquisition Unit

The Acquisition unit is the core sensor of the whole transmission distribution fault indicator system. Relying on the small current self-taking technology and wireless communication technology, the acquisition unit is able to report real-time monitoring data to ensure the utility staff can keep tracking of the line conditions.
