Remote monitoring and advanced analysis of power grids and surge arresters above 1 kV
Measurements and perception
Resistive component from 0 to 3 mA (± 10%)
Arrester measurement standard: IEC 60099-5
Detection: failure, fire, voltage, counter counter, device temperature, ambient temperature, slope, location
Measuring cycle: 1 hour
Frequency range: 48 to 62 Hz
Temperature range: -40 ° C from + 85 ° C
Housing and assembly
Ingress protection: IP 67
Housing material: Thermoplastic V-0 (UL 94), stainless steel A2 or A4
Bluetooth, 4G/5G or LoRaWAN
– In real time – all significant errors (fire, destruction of the arrester, exceeding the recommended measurements),
– Once a day – UDP package; for other measurements (with default settings),
– Once every seven days – MQTT package; for other measurements (with default settings).
Before delivery check
4G and 5G mobile network:
• the presence of a mobile network signal at a standstill and,
• eligibility for data transfer with the mobile operator.
Read the user manual carefully before starting the installation.
It can be found on the back side of the packaging. The RAM-1 device must be installed on the grounding side of the surge arrester. There must not be a direct connection between the grounding side of the surge arrester and the RAM-1 device without and intermediate grounding. The metal plate of the RAM-1 device must be turned towards the grounding point. If the device is installed incorrectly it will not work properly. The installation guide for the installation on poles/towers are not necessary. The device must be installed in the top third of the pole/tower.Installation guide
