The digital switchgear developed by ABB can replace traditional current transformers ( CTs ) and Voltage Transformers ( VTs ) with advanced sensor technology . This shift allows for a more efficient monitoring and management system within mining operations . By utilising just two sensors capable of covering a wide current range , ABB significantly simplifies stock management in mining environments .
This innovative switchgear connects seamlessly to supervisory control and data acquisition ( SCADA ) systems or distributed control systems , facilitating real-time data access and management . The energy consumption associated with conventional CTs can be substantial over the life of switchgear ; in contrast , the sensor technology provides a millivolt signal , resulting in considerable energy savings over the lifespan of the equipment . These savings not only enhance operational efficiency but also contribute to miners ' carbon neutrality targets .
ABB also showcased a compact substation made from glassreinforced plastic , which offers superior insulating properties and increased fire resistance compared to traditional steel enclosures . This innovative material represents ABB ’ s focus on creating safer and more efficient solutions for the mining industry .

Digital switchgear : A leap forward ABB also invests heavily in R & D focusing on digital switchgear that can replace traditional components with sensor technology , enhancing efficiency and reducing costs . This innovation simplifies stockholding and transport logistics , saving energy and contributing to carbon neutrality goals . Quite a few of ABB ' s factories are already carbon neutral , with plans to complete all factories by 2030 . “ The company helps clients meet their carbon neutral targets by providing sustainable Solutions . While South Africans may not be fully aware of carbon taxes , exporters are , and ABB assists them in becoming more efficient to comply with these regulations ,” says Graham Abrahams , senior vice president , Electrification , Commercial Leader .
As the European Union implements carbon taxes , ABB is actively engaging with mining companies to help them navigate these challenges . While awareness of carbon taxes may vary across regions , larger mining companies are increasingly recognising the implications for their operations . “ ABB ’ s expertise and technologies aim to enhance efficiency and reduce emissions , thereby mitigating the financial impacts of carbon taxes ” concludes Abrahams . •
