The smart RAM-1 device is intended for remote monitoring and advanced analysis of power grids. Power grids become Smart with the use of the RAM-1 device, which improves the operating process and the reliability and stability of the electricity transmission and distribution networks. If attached to a gapless surge arrester with a continuous operating voltage above 1 kV the RAM-1 device can measure the resistive component of the leakage current. This innovative method of extracting the resistive component of the leakage current conforms to the standard IEC 60099-5. The measurements can be tracked either via an online or mobile application. One RAM-1 device installed on a surge arrester is sufficient for monitoring a group of three surge arresters installed on one post.
The smart IoT device RAM-1 offers:
• Machine learning;
• Simple installation;
• Communication: 4G, 5G or LoRaWAN;
• Up to 20 years maintenance free and without communication costs.
RAM-1 tracks, analyses and immediately reports the following parameters:
• Excessive environment temperature (fire indication);
• Inclination/tilt or collapse of the pole/pylon/tower;
• Power outage (the presence of voltage);
• Lightning counter and detection of other surge manipulations in network;
• Destruction of arrester;
• Operation of disconnecting device;
• Location of event or fault (provides navigation to the location).
RAM-1 Versions:
• RAM-1 MV A2(A4)* – Voltage up to 110 kV and HV towers;
• RAM-1 HV A2(A4) – Voltage above 110 kV.
* Stainless steel quality A2 or A4.
