Switchgear Fault Detector

ABB’s TVOC-2 Arc Guard System protects equipment and personnel from dangerous arcs, and prolongs equipment life. A safety device that detects faults in low- and medium-voltage switchgear, the system clears an arc in a short time, reducing the energy in the arc so that personal injury and equipment damage are kept to a minimum. The Arc Guard System is user-friendly, easy to install and flexible, with mounting options on a DIN-rail or directly on a panel wall on both new installations and old switchgear.

Arc Flash Relay

The AF0500 from Littlefuse is a microprocessor-based arc flash relay that limits arc-fault damage by detecting the light from an arc flash and rapidly tripping the feeder breaker. The unit is suited for switchgear, transformer and power-converter applications. Sensors, inputs and connections are health-monitored to ensure fail-safe operation. A secondary solid-state trip circuit provides a redundant trip path. A USB port is used for configuration and access to event logs. The relay includes an Ethernet interface and supports Modbus TCP communication. Zone-tripping, upstream breaker-tripping and tie breaker-tripping applications can be easily configured. Control inputs allow interconnection of multiple AF0500 units to form a system.

Guide to Arc Flash Hazards

“How to Reduce Exposure to Arc Flash Hazards” is a free, downloadable guide from GE Industrial Solutions that explains arc flash, its dangers, and company solutions to mitigate them. The solutions are part of the company’s ArcWatch set of technologies, WaveForm Recognition (WFR) and Instantaneous Zone Selective Interlocking (I-ZSI) which, when used in combination with one another, allow system design that does not require compromise between instantaneous protection from arcing faults and full (.01 second) selective coordination. ArcWatch technology is included in nine company products, also described in the guide.

IR Viewing Windows

Fluke Infrared (IR) Windows eliminate the need to open enclosures and expose technicians to arc flash hazard. They feature arc-resistant crystal optics that are engineered to withstand the extreme pressures and temperatures of an electric arc-fault event up to 50 kA. Their Kwik Twist magnetic security cover further protects the viewing pane from accidental external impact, and is locked in place with a security access key. For added convenience, the Kwik Twist cover magnetically sticks to the metal panel. The units’ AutoGround feature automatically grounds the Fluke IR Window upon installation, without additional steps or testing.

Arc Flash Protective Face Shield

The Weight-Balancing Arc Flash Protection Face Shield from Salisbury by Honeywell stows in a balanced, compact position, centered over the top of the hard hat when not in use. It has an ATPV rating of 20 cal/cm2, and uses nanotechnology to provide a clearer, more transparent window for improved visibility. The face shield unit includes ventilation ribs that allow a natural convection air flow through the top of the face shield. This reduces fogging of the visor, lowers CO2 levels and improves comfort.

Flame-Resistant Coverall

The Standard Coverall from Benchmark was developed primarily for arc flash protection. With an arc flash rating of 13 cal/cm, it is an acceptable coverall for HRC 2, single garment compliance. It can also be used to protect against flash fires. When tested on the instrumented mannequin, according to NFPA 2112 (50% body burn threshold), this coverall received a 7.38% total body burn.
