More safety in power distribution grids

The requirements for energy distribution in terms of usage, functionality and structures are ever changing. In addition to grid loads due to highly fluctuating energy flows from regenerative energy producers, there will also be increased demands from charging stations for e-mobility in the future.

E⁴-NH-Fuse-Switches, vertical design and Fuse-Rails

The E4-series is a standardized device series for the power distribution offering the basic requirements for a smart energy distribution grid. The core element of those smart energy distribution grids is the recording and evaluation of performance data. The E4 products offer the opportunity to record the data easily and conveniently. Years of experience and technical specification have gone into the development of this series in order to achieve the optimum result in terms of technical values and safety. A perfect interface for your energy distribution which can be upgraded to the various requirements at a later date.

Preassembled NH fuse-switches, vertical design

Changes in energy distribution increasingly require the provision of measured values for energy management systems. To meet this challenge, EFEN offers convenient solutions with preassembled NH fuse-switches, vertical design, current transformers (xxx A/1 A) or low-power current transformers (xxx A/333 mV). These devices are completely designed for direct on-site installation and can be easily integrated into data networks by means of connection terminals. The installation dimensions of the switchgear remain unchanged, so there is no need for time-consuming system modifications.

Measurement Electronic Module (MEM)

Changes in the power supply network cause new challenges for all parties involved. Due to new power sources, energy generation will be more remote, volatile and decentral. It is crucial to combine the current status values to supply and demand as there are highly fluctuating energy flows and rising consumption peaks as a result of the charging processes of e-mobility. The intelligent use of the existing power network structures is opposed to network expansions which requires measurement of the grid at various neuralgic points.
With our Measurement Electronic Module EFEN offers a space-saving possibility – for more intelligence in your grid.
