TVOC-2 - Arc Guard SystemTM
Date: Jan 06, 2025Views:
Arc Guard System™
TVOC-2, ABB's Arc Monitor, builds on the well known TVOC design. Its new functions and features improve an already great product, putting even more focus on reliability, flexibility and simplicity.Arc Guard System™ protects people and equipment, and eliminates unnecessary production stops. Arc monitor type TVOC-2 is ABB's state-of-the-art solution for arc fault protection in all applications, providing functional safety.With over 35 years of experience, Arc Guard System™ has become an industry standard in several key markets, helping to protect personnel and businesses around the world. Typical applications include all low- and medium-voltage switchgears.
Reliability
• Certified according to functional safety (SIL-2) standard
• Over 35 years experience in Arc Guard Systems
• Pre-calibrated optical sensors
Flexibility
• HMI (Human Machine Interface) can be mounted
on the panel door
• COM Module operates in the same way as HMI. With added
ability to communicate with a remote station using Modbus
RTU
• Expandable with up to 30 optical sensors
• Configure the system according to various needs
Simplicity
• User-friendly start-up menu
• DIN-rail or wall-mounted
• Easy to expand as the switchgear functions are added
Arc Guard System™
Arc Guard System™ quickly detects an arc fault and trips the incoming circuit-breaker. Using light as the main trip criteria, Arc Guard System™ trips instantaneously. Thanks to this key functional advantage, it overrides all other protections and delays,which is crucial when reaction times need to be measured in milliseconds.
Arc Faults
Short-circuit faults in LV and MV switchgears are often accompanied by an electric arc. An arc fault always leads to considerable damage to equipment and injury to personnel unless it is detected very quickly. To avoid
serious damage and give the person involved a good chance of surviving the accident without severe injury, the fault should be disconnected as fast as possible, typically in less than 50 ms.
Arc Monitor
With its modular concept, the Arc Monitor is designed to fit all types and sizes of low- and medium-voltage switchgears.It is designed according to Functional Safety, and is SIL 2-certified according to IEC 61508 and IEC 62061 which puts full focus on reliability. This corresponds to performance level d according to EN ISO 13849-1. Safety functions are exclusively handled by hardware. In addition, the system, trip logs and user-interface are all microprocessor-monitored.
