ABB’s New ANSI Medium-Voltage Digital Switchgear Offering Helps Customers Improve Safety, Efficiency, and Performance

ABB’s ANSI medium-voltage digital switchgear is a new member of the ABB Ability portfolio of connected solutions and is based on the optimized integration of current and voltage sensors into medium-voltage switchgear, combined with the latest Relion® protection and control relays and the capability of the IEC 61850 standard for communication. Offering the opportunity to integrate SwitchgearMD technology for continuous and remote condition monitoring of switchgear and its key components, this new technology for protection, control, automation and monitoring results in a solution that is continuously self-supervising with increased possibilities for error-detection.

“ABB’s medium-voltage, metal-clad digital switchgear helps create a safer and simpler system that reduces the lifetime cost of ownership and results in a more reliable system to provide consistent power distribution,” said Dick Jackman, Global Product Group Manager for ANSI MV+LV Switchgear, ABB. “It is a perfect fit for environments such as oil refineries, utility substations, and data centers, where a reliable power supply must be ensured and future-proofing the gear and its environmental impact is a concern.”

Safety by design

ABB’s digital switchgear benefits from safety by design. The use of sensors helps eliminate hazards associated with open current transformers and ferroresonance in potential transformers. The simpler electrical construction leads to fewer internal points of failure and creates higher reliability. This simplicity also helps reduce wiring errors and leads to faster installation. In addition, the reduced weight of all components makes handling of the gear easier.
