Quality and uninterrupted supply of energy to industries and the population is a vital component of infrastructure provision. Often, power transmission lines are damaged, not always due to natural factors such as cable breakage or "swaying" due to freezing. Metal supports of power transmission lines (PTL) are an attractive target for petty criminals who then sell their elements as scrap metal, leading to serious consequences - power outage in entire villages and halting of operations at enterprises due to cable breakage caused by the tilting or falling of supports. Another issue is the search by customer teams specifically for the affected areas, which delays the restoration of power supply. The task set by the customer is to carry out prompt monitoring and provide immediate notification of vandalism on the supports, indicating the precise location and type of impact on the support.

As a result of studying structures of various types of PTL supports, key equipment requirements were approved: autonomous operation without a power source at any time of the year, outdoor enclosure design, compact size for inconspicuous placement on the support, receiving an alarm notification after the start of an impact on the support in no more than 1 minute. Our engineers have developed a device that detects vibration according to established algorithms depending on the support structure and remote configuration depending on the location and characteristics of the support. Special instant notifications were developed based on Fleetix software, indicating the location and number of the support where vandalism was detected. A pilot batch of devices was installed for a 3-month pilot project during the winter season, during which minor adjustments to the design were made, equipment firmware was updated, and trigger algorithms were adapted.

As a result of equipment development and software refinements, the customer received a solution for round-the-clock and year-round monitoring of the condition of PTL supports. Devices with autonomous power supply ensured continuous and stable operation of the equipment at any time of the year and provided prompt notifications within 30 seconds from the moment of impact detection on the supports. Through special algorithms, we taught the device and software to filter out false triggers, such as strong winds, snow, or birds. In the software, PTL supports were automatically displayed on an electronic map using a GPS receiver, with simultaneous visualization of problematic supports (not in communication or with alarm messages). The dispatch service and security service received a tool with instant notifications to form operational teams for responding to problematic supports or intercepting perpetrators depending on the distance to the nearest team.
