Smart solutions for remote monitoring

1 1.1 Smart IoT Device RAM-1: Overview RAM-1 is an intelligent IoT device specially designed for real time remote monitoring and advanced analysis of surge arresters and power grids. By incorporating the RAM-1 device in to the power grids, they are elevated to a smart level, resulting in enhanced operational processes, improved reliability, and increased stability of electricity transmission and distribution networks. When connected to a gapless surge arrester with a continuous operating voltage above 1 kV, regardless of the manufacturer, the RAM-1 device will be able to extract the...

1 1.2 RAM-Center Application The authorized RAM-Center app by Izoelektro provides a comprehensive overview of installed RAM-1 devices, allowing for effective monitoring of surge arresters within power grids. RAM-Center presents in-depth graphical monitoring of measurements, an extensive log of previous measurements, and instant push notifications for alerts (such as fire, sudden tilt, damage or failure of the surge arrester) as well as predefined events (such as surpassing the leakage current threshold). The app also offers GPS coordinates for installed RAM-1 devices and facilitates direct...

1 1.3 RAM-1 Characteristics The RAM-1 Smart IoT device provides: • advanced machine learning capabilities, • simple and easy installation, • wireless communication: 4G, 5G, or LoRaWAN, • on-site reading and configuration function via the RAM-Center app (Bluetooth). RAM-1 reports the following parameters: • the resistive component of leakage current, • excessive ambient temperature (fire detection), • inclination/tilt or collapse detection, • power outage detection (presence of voltage), • lightning counter and detection of surge manipulations in the power grid, • surge arrester destruction...
