TECHNICAL DATA

Usage

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

Work environment

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

Communications

Bluetooth, 4G/5G or LoRaWAN

Communication cycle:

– 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.

Installation guide

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.
