TVOC-2-240 1SFA664001R1001

Product Description

The ABB TVOC – 2 – 240 1SFA664001R1001 is a sophisticated arc monitor module, playing a pivotal role in safeguarding industrial electrical systems. It is a key component within the TVOC – 2 arc guard system, designed to detect and respond to arc faults promptly.

1. High – speed Arc Detection

Equipped with advanced optical sensors, this module can swiftly detect the light emitted during an arc event. Once an arc is detected, it sends an electrical signal via fast IGBT contacts to a nearby breaker within an astonishingly short time of 1 ms. This rapid response is crucial as it enables the breaker to quickly cut off the power supply, thereby extinguishing the arc and preventing potential disasters such as fires, equipment damage, and harm to personnel. For example, in a large – scale power distribution substation, where high – voltage electrical equipment is in operation, any arc fault could lead to a major blackout and safety hazards. The TVOC – 2 – 240 1SFA664001R1001 module can effectively detect and address such issues in a timely manner.

2. Multiple Detector Inputs and Selective Tripping

It comes with 10 detector inputs, providing flexibility in sensor installation. This allows for comprehensive coverage of different areas within an electrical installation. Additionally, the module has the capability to trip up to three breakers with zone selectivity. In a complex industrial plant with multiple electrical zones, this feature ensures that only the breakers relevant to the area where the arc fault occurs are tripped. This helps in minimizing the impact of the fault on the overall operation of the plant, as non – affected zones can continue to function normally.

3. Expandable Configuration

Up to 2 extension units can be connected to the TVOC – 2 – 240 1SFA664001R1001. By adding these extension units, the number of light detectors can be extended from 10 to 30. This expandability makes it suitable for large – scale electrical systems, such as those found in manufacturing facilities, power plants, and petrochemical plants. These facilities often have extensive switchgear and electrical equipment that require thorough arc protection.

4. Human – Machine Interface (HMI) Integration

The module includes an HMI that can be conveniently placed on the outside of the electrical cabinet door. This HMI provides operators with real – time information about the status of the arc monitor, such as whether an arc fault has been detected, the location of the fault (if multiple zones are monitored), and the status of the connected detectors. It also allows for easy configuration and calibration of the module, enabling maintenance personnel to set parameters according to the specific requirements of the electrical system.

5. Compatibility with Diverse Electrical Systems

The TVOC – 2 – 240 1SFA664001R1001 is designed to be compatible with a wide range of electrical systems. It can operate with supply voltages of 100 – 250V DC or 100 – 240V AC at 50/60Hz. This wide voltage range makes it suitable for use in different regions and applications, whether in industrial plants with standard AC power supplies or in certain DC – powered systems.
