In April 2023, we expanded Company L's temperature monitoring system for 6.6 kV power cables between the receiving substation and the factory distribution room.

Additional optical channels were connected to the existing system. Four one-kilometer optical cable runs were installed to monitor the phases of two power circuits, providing temperature measurements at 50 cm intervals.

Company L now monitors approximately 100 km and 200,000 temperature points using four DTS units and 29 channels.

Functions include phase-by-phase high-voltage cable monitoring, distributed fiber optic temperature monitoring, power and industrial equipment monitoring, SMS alarm and event notifications, web clients, and accumulated temperature data analysis dating back to 2016.
