Overhead fault monitoring
TS200MT/AT: fault detector for medium- and high-voltage lines
Detects temporary and permanent faults and the presence or absence of voltage and current at the point where it is installed, and reports them in real time with a timestamp.
What it is for
Know where voltage or current was lost
Reports, with a timestamp, the presence and absence of voltage and current, and temporary and permanent faults at the installation point.
Install it without field configuration
It installs without field configuration, on bare or covered cables of 6 to 33 mm, on conventional or compact grids.
No batteries, no maintenance
Solar panel and maintenance-free ultracapacitors. 40 hours of autonomy in normal mode and more than 20 in economy mode; a full charge in sunlight takes 20 to 120 minutes depending on the weather.
Versions are available for medium voltage up to 34.5 kV and high voltage up to 88 kV. A permanent-fault LED on the underside shows the event on the device. In economy mode the device suppresses temporary and permanent fault monitoring. Detection values can be configured at the factory.

How it integrates
Sigfox communication
Messages travel over the Sigfox network, with an integrated module and open frequencies, with AES-128 security and encrypted callback. Any change of state triggers an immediate timestamped message; with no events, it sends 2 keep-alive messages a day. With Sigfox, the customer's existing network is used.
Platform and SCADA
Packets are redirected to Habitat, which acts as a database and converts the information to DNP3 and IEC 104 for the operations SCADA server.
Factory values
