Transmission & Distribution

Contributing to smart grids with high class components

At Weidmuller, we know power utilities today face many challenges. The energy transition is a common goal around the globe, and electrical grids play a key role in the decarbonization targets of most governments. Renewable integration, distributed generation, self-consumption, electrical vehicles, etc. will only be possible if electrical grids become smart grids. Smart grids are only possible with digitalization, communications, cyber-security and analytics. Weidmuller's product portfolio includes first-class products ranging from "smart" connectors to Industrial Analytics. With these solutions, utilities can make their grids smarter while meeting extremely high requirements for reliability and availability.

As a valued partner for transmission & distribution, our customers can rely on:

Safety for maintenance personnel

Connections between protection & metering equipment and current transformers may cause incidents that threaten 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 the Power-Supply family (including UPS) that is used by international vendors in their solutions for automating secondary substations, etc.

Industrial analytics for higher added-value services

Smart Metering and Smart Grids deliver power utilities a huge amount of information about their grids. They can use analytics to make many improvements in terms of grid reliability, energy quality, cost savings, safety, etc.

Facing market challenges with innovation and passion

Smart Metering

Energy suppliers are increasingly replacing traditional electricity meters with smart meters. Because of this, we at Weidmuller, have developed many different customized 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 widely used to protect these newly installed electronic meters.

Distribution automation

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

Substation panels and MV switchgear

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

Energy Management

From the energy meter to measure power consumption in substation panels and MV switchgear to the IEC 61000-4-30 Class A Energy Analyzer to measure the quality of energy at the borders of the electrical grid: At Weidmuller 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.

In power substations, the connections between protection, control and metering devices with instrument transformers are critical because they impact the safety of personnel and devices. Our new TTB range of Klippon Connect transformer terminal blocks provides the perfect option for these connections by ensuring simplicity for any connection circuit and safety for people and assets.

Forced short circuit mechanism for 100% safe handling (make before break)
Unique lever mechanism offering maximum contact reliability and optimal visibility for the operator
Captive components (accessories) to increase reliability during installation and maintenance
Dedicated cross connection channel before and after the disconnect contact for maximum flexibility

More information

Substation Line

Ethernet Switches IEC 61850-3 compliant

Ethernet Switches are required in substation automation systems, so they are installed in the same cabinets as protection & control IEDs (Intelligent Electronic Devices). Accordingly, it is important that the Ethernet switches are also "substation hardened" from the perspective of immunity to EMI (Electromagnetic Interference). Our Substation Line perfectly meets all of the requirements for Ethernet Switches in T&D assets.

Compliance with 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 10 Gbit/s and IEEE 1588v2 (PTPv2) compliance to meet the requirements of the digital substation (Process Bus)
