ABB Unveils ABB Ability Digital Switchgear for Secondary Distribution Networks

With the launch of ABB Ability AIS for MV – UniSec Digital – the portfolio of MV digital switchgear is prolonged to include supplementary power distribution needs as well.

As a part of the ABB Ability portfolio of linked digital solutions, digital switchgear helps customers gain operational effectiveness and brings unparalleled flexibility, driving the fourth industrial revolution.  With digital switchgear, customers can be helped by a technology which will deliver elevated flexibility, stability and safety, and also reduces switchgear weight and footprint.  Digital switchgear supposedly has as much as a 30 percent shorter delivery time in contrast to conventional switchgear and installation and commissioning time is reduced by 25 percent. Because of sensor technology, safety is further improved during installation and operation.

Digital switchgear is dependant on the incorporation of current and voltage sensors into medium-voltage switchgear, coupled with ABB’s Relion protection and control relays, and the capacity for the IEC 61850 standard for communication.  With digital switchgear, changes are simple to put into action, when electrical loads are changed or added, or a requirement for variation is recognized late in the switchgear project.  The new generation of switchgear enables versatility and growth of the switchgear lineup without resorting to complex additional wiring.

Digital switchgear is definitely modified, as changes can be created using software logic in the protection relays, using the idea of interoperability in the IEC 61850, the state-of-the-art communication standard for the challenges in connected Industry 4.0 ecosystems.  Digital switchgear exploits the potential for cyber-physical systems to enhance efficiency, productivity and serviceability.  Furthermore, with digital switchgear, it may be straightforward to apply energy and power management solutions which help guarantee higher availability and excellence of power to ensure continuity and reduce downtime. These new capabilities of Industry 4.0 lead to smart grids, smart energy, smart cities and smart industrial plants.

UniSec is ABB’s established AIS product family for secondary power distribution.  UniSec Digital is suitable for applications up to 24kV.
