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.
The Guard System is suitable for equipment with 24- 48 volt DC ranges as well as 100-240V AC/DC. The new 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 the Emax 2 smart circuit breaker.
The system can be equipped with up to 30 optical sensors, enabling a single unit to cover multiple switchboard cabinets. Once installed, it is able to detect arc initiation and, in less than one millisecond, send a signal to an Emax 2 circuit breaker to open. This makes it a fast and effective system for reducing risks to personnel and equipment.
