ABB TVOC-2 Arc Guard System communication module

ABB has launched a plug-in communication module for its TVOC-2 Arc Guard System. The communication module provides operators with real-time status updates and instant information on the location of any arcs. When also connected with the ABB Emax 2 smart circuit breaker and its cloud-based services, the new module is an enabling technology for the Internet of Things, Services and People, allowing operators to take immediate action, wherever they are.

With arc flash protection, time is a critical factor in minimising injury risks and property damage and in maximising productivity. The communication module ensures that information regarding any trip and the status of the system travels faster, reaching the right people sooner.

The TVOC-2 Arc Guard System is suitable for equipment with 24–48 VDC ranges as well as 100–240 V AC/DC. The plug-in communication module replaces the standard TVOC-2 HMI, sending data via MODBUS RTU to any remote station or other intelligent switchgear technologies, such as ABB’s Emax 2 smart circuit breaker.

The TVOC-2 system can be equipped with up to 30 optical sensors, enabling a single unit to cover multiple switchboard cabinets. Once installed, the system is able to detect arc initiation and, in less than one millisecond, send a signal to an Emax 2 circuit breaker to open.
