ABB Ability Circuit Breaker Upgrade for MV

The VD4 Digitup modernization solution makes any existing medium voltage switchgear ABB digital compliant.

VD4 Digitup combines the latest medium voltage circuit-breaker with sensors and IEC 61850 based Relion® protection relays. The scope of this solution is switchgear modernization with the implementation of IEC 61850 station and process bus.

Key benefits

  • Permanent supervision of all analog and digital data on the process bus enables optimized maintenance and fast actions in case of failures
  • IEC 61850 standard compliance enables efficient system upgrade in the future.
  • Asset management is ensured with second-by-second analysis of circuit breakers performance.
  • The system is cyber secure.
  • Electrical shock risk is reduced by substituting copper wires with fiber cables.
  • Consumption and dissipation reductions support energy efficiency programs.

Key features

  •  Any existing panel can be completely modernized regardless of the age, design and brand, becoming ABB digital compliant.
  • VD4 Digitup allows a quick and easy implemention into a truly digital switchgear also when the panel designs are not set for the application.
  • VD4 Digitup is a core enabler to increase flexibility, efficiency, safety, productivity and reliability for plant operators and to lower cost of operation.
