Smart products from EFEN for smart energy grids

The challenges of the future pose major challenges for all those involved in electrical power distribution. From the shortage of skilled workers to increasing cost pressure, those involved must find solutions to ensure their success. Rittal’s new busbar system – RiLineX – has created a platform to meet these challenges.

RiLineX offers a modular, manufacturer-neutral, and license-free busbar system platform suitable for a wide range of applications – from the process industry to renewable energies and IT infrastructures. The platform enables quick, easy, and secure installation, thus significantly contributing to increased efficiency.

As an official technology partner, EFEN GmbH, with its renowned and tested quality, complements the range of products and services with NH Fuse-Switch, vertical design for the 60 mm busbar system.

With the simple and secure hook connection to the IP2x system in RiLineX, installation is quick and safe. The proven and well-known NH Fuse-Switch, vertical design of the E³ series offer a high switching category and proven parallel isolation, which underscores their safety. The various cable connection options support speedy installation.

With the E⁴ series, EFEN offers a standardised range of devices for energy distribution, which provide the basic requirements for a smart energy distribution network. The core element of intelligent energy networks is the recording and evaluation of power data. The E⁴ products enable you to record this data easily and conveniently.

Years of experience and technical specifications have been incorporated into the development of this series in order to achieve the optimum result in terms of technical values and safety.

The changes in the energy supply grid mean new challenges for everyone involved. New energy sources are making the generation of energy more remote, volatile and decentralised. The current grid status values must be combined in line with demand due to the strongly fluctuating energy flows and, with increasing e-mobility, higher consumption peaks for charging processes, in order to smartly combine supply and demand. Here, the intelligent utilisation of the existing grid structure is opposed to grid expansion and it is important to measure the grid at various neuralgic points. With the measured value acquisition module 1, EFEN offers you a space-saving option – for more intelligence in your grid.

The requirements for energy distribution are changing rapidly and comprehensively in terms of utilisation, functionality and structures. To ensure reliable operation, supply network operators, industrial companies and facility management increasingly require up-to-date measured values and information about the load on their distribution networks. This information needs to be provided almost in real time in order to be able to take appropriate control measures, particularly in hot spots such as local grid stations.

The smartisation of energy distribution grids is a practical solution for the systematic measurement of energy values: simple and interruption-free installation in existing systems, flexibility with regard to the number of measurement points and handling without the need for extensive training. With the Smart Grid Interface Module Comfort, EFEN offers a modular system for recording electrical and other physical measured variables in distribution cabinets and cable distributors.

Individually configurable

Thanks to its compact design, the SGIM Comfort fits into the spare space in the cable distribution cabinet and offers a wide range of possible applications. With just one device, you can carry out 3-phase monitoring of up to 14 low-voltage connections. Upgrades with measuring and communication modules complete the modular system.

Simple installation

Uninterruptible ‘plug & play’ installation under voltage on a 185 mm busbar system. In conjunction with the Rogowski coils, you have a quick and easy way to integrate the complete current measurement into your existing system at a later date – freely configurable according to your requirements. We recommend our pre-assembled E³-NH fuse-switch with integrated current transformers for a new installation.

Integrated safety

The integrated CAT IV overvoltage protection safeguards your devices. You can also rely on the protection of an integrated firewall, so that your network analysis data is protected against attacks and secured in accordance with modern transmission protocols.

The ongoing energy transition is leading to ever larger and more powerful photovoltaic systems. For greater efficiency, PV systems on commercial buildings, industrial and ground-mounted systems are increasingly being designed for higher output voltages. String inverters with 800 V AC are progressively being used, especially in the medium power range.

The higher AC output voltage places higher demands on electrical safety. EFEN offers optimized solutions for 800 V string inverters. The E3 and E4 fuse-switch-disconnectors have powerful contact devices that enable reliable disconnection of the arc at this voltage level. The compact EFEN NH fuselinks for 800 volts reliably protect the system from damage. The innovative fusible link design in the compact standard NH housing offers low power loss and a high rated breaking capacity.
