Power transmission and power distribution

Connecting energy intelligently – for tomorrow's grids

Operators face growing hallenges: fluctuating feed-in from renewables, rising loads and increasing demands on controll and security. Modern grids must remain flexible, scalable and secure, even under dynamic conditions. Weidmüller provides smart connection solutions that combine proven technology with digital functionality, enabling safe and efficient operation in critical grid environments.

Reliable solutions on which you can build – for secure connectivity in power distribution

Safety for maintenance personnel

The connections between protection & metering equipment with current transformers may provoke incidents that pose risks to the safety of equipment and personnel. Our aim is to ensure safety on the component side (make-before-break concept), avoiding human mistakes in these critical connections.

Reliable electronic products for harsh environments

We offer a wide range of products meeting the most demanding requirements of Power Utilities: IEC 61850 Ethernet Switches, Class A Quality Analyzers as per IEC 61000-4-30, or Power-Supply family (including UPS) that is being used by international vendors in their solutions for automation of secondary substations, etc.

Industrial analytics for higher added-value services

Smart Metering and Smart Grids allow Power Utilities to have a huge amount of information about their grids. The use of analytics may bring them many improvements in terms of reliability of the grid, quality of the energy, cost savings, safety, etc.

Facing market challenges with innovation and passion

Smart Metering

Energy suppliers are increasingly replacing traditional electricity meters with smart meters. At Weidmüller, we have therefore developed many different customised mounting rails that facilitate the replacement and testing of meters while ensuring the safety of equipment and personnel. We also have a comprehensive range of surge protection devices (Type I and II) that are being widely used to protect these newly installed electronic meters.

Distribution automation

Distribution automation is one of the crucial steps of power utilities towards smart grids. Monitoring and automation of secondary substations require reliable and compact products and the Weidmüller portfolio includes several of the key elements required at the “smart” secondary substations. We can provide the power supply back-up system, the LAN/WAN communications devices, surge protection as well as the necessary components for the internal connectivity.

Substation panels and MV switchgears

The protection and control system of a substation requires thousands of critical connections with the primary equipment. Weidmüller's full range of modular terminal blocks and markers offers the best alternatives to connect the different type of signals in a reliable and safe way. Our portfolio also includes a large product family of signalling relays. This enables us to provide the complete range of accessories required for the control cabinets in transformer stations.

Energy Management

From the energy meter to measure power consumption in aubstation panels and MV switchgears to the IEC 61000-4-30 Class A Energy Analyser to measure the quality of energy at the borders of the electrical grid: At Weidmüller we have Energy Management Solutions including not only the main field devices (energy meters and analyzers) but also current transformers, Rogowski Coils, management software, and analytics.

Substation Line

Ethernet Switches IEC 61850-3 compliant

Ethernet Switches are required in Substation Automation Systems and therefore are installed in the same cabinets as Protection & Control IEDs (Intelligent Electronic Devices). Accordingly, it is important that the Ethernet switches also become “substation hardened” from an EMI (Electromagnetic Interference) immunity perspective. Our Substation Line perfectly matches all the requirements of Ethernet Switches in T&D assets.

Compliance of IEC 61850-3 and IEEE 1613 standards
Several available models with different port arrangements; from compact DIN-rail to modular 19” rack devices
Redundant power supply in all models and wide operating temperature range from -40 to 85ºC
Interfaces up to 10Gbit/s and IEEE 1588v2 (PTPv2) compliance to meet the requirements of the Digital Substation (Process Bus)
