Assembled measuring cases
Semi-permanent measuring or no space for a fixed power analyser?
Are you considering installing a meter temporarily, or is there limited space for a permanent energy meter in your setup? Fortop has a standard solution in the form of fixed measuring cabinets that are delivered completely assembled and tested. Simply connecting the measuring voltage and the current transformers is sufficient.
The cabinets can be fitted with a power quality analyser or a power analyser, both in a panel-mounted and a DIN-rail version. The cabinets are supplied with a drawing, a connection diagram and the coding of terminals and components.

Measuring cabinet readout
Reading via a Local Ethernet Network
The metering cabinets are equipped with an Ethernet connection, allowing them to be integrated into the local network. Direct connections can be made to the meter for reading the embedded web interface or using the GridVis application. The meters can be easily integrated into higher-level systems using standard protocols such as Modbus TCP and BACnet/IP.
Remote Access via the fortop VPN Service
If you want access to your metering cabinet independently of your own IT infrastructure, we can provide you with access to the energy meter through our VPN server. Through a VPN login on your laptop or workstation, you are guaranteed a secure and always available connection for a fixed monthly fee. The connection can be established via both a wired network and a 3G/4G/LTE network.
Data Logging and Web Reading via the fortop Cloud Service DCEM Cloud
For a fixed monthly fee, we handle data storage and web visualisation of key measurements, voltage sags and current peaks, power quality reports, and energy consumption. Even in the event of a data connection loss, no data is lost because of local data storage. The web visualisation includes an export function for all available measurements.
