A device for full control of your electricity grid

A device for full control of your electricity grid

There are 6 available device configurations depending on your voltage and current measurement needs

Voltage connection
Current connection

Installation is possible outdoors regardless of temperature and weather



Key installation aspects in comparison:

Our approach
Installation process takes at least 2 hours
Set up in 15 minutes
Power supply must be disconnected
Power supply doesn't have to be disconnected
Electrical installation is modified (wires to be cut)
Electrical installation doesn't have to be modified
Readings are taken from time to time
Complete data analysis available on-line

The GRIDLINK accessory device conveniently and quickly enables the system to determine the status of fuses in transformer stations. For example, you can instantly see that there are no problems with wiring, but an outgoing line to the factory or a household has a broken fuse


Combination with GRIDLINK, using PowerLine
Monitoring of max 15 outgoing connections
IP67 body
