What is an arc flash?
Human safety is critical to utilities and industries, including oil, gas, water, wastewater, and metals and mining.
Arc flash is a hazardous situation with a release of energy.
The energy from an arc flash event can cause injury.
How is the arc generated?
Arc flashes occur when the insulation or air separation between energized components within a circuit is compromised. Arc flash events can be caused by a number of factors, such as a two-phase short circuit, which can cause phase-to-phase faults. Common examples of causing phase-to-phase failures include dropped tools, accidental contact by maintenance personnel, build-up of corrosion or conductive dust on conductors, and the presence of pests, such as rats, or snakes, that come into contact with energies.
Danger of Arc Flash
Arc flash events can result in dangerous and potentially lethal heat, ultraviolet radiation, explosion pressure, flying shrapnel, and deafening sound waves.
4. Reduce damage to switchgear:
With Arc Flash Hazard Protection, equipment damage can be minimized during an arc flash event, allowing affected equipment to be restored faster and at a lower cost. In addition, the availability of the power system is maximized.
5. Maintain selective coordination:
Arc flash events trigger immediate response while coordinating with external protection for downstream faults.
6. Stay outside the danger zone:
Get metering, event and maintenance information remotely from the relay via Ethernet or serial communication to maintain a safe distance. An optional delay circuit breaker trips or closes at the push of a button, allowing personnel to move to a safe distance.
Arc protection solutions
Bare fiber sensors detect light from arc flashes over the entire length of the fiber loop. This type of sensor is used for large areas.
Easy-to-install point sensors such as busbars detect light from arcs. This type of sensor is used in areas such as closed circuit breaker rooms.
Shenzhen Jinzhi Optoelectronics Technology Co., Ltd. provides induction series products for arc protection solutions
1. Jinzhi provides: light detection point sensor
Model:KINZ-CG01&KINZ-CG02
Plastic Fiber Optic Connectors for Point Sensors
Describe:
KINZ-CG01 is an optical point sensor with self-supervision function.
The light that meets the point sensor is captured and fed into a plastic optical fiber (POF). The self-supervision function is achieved through the built-in coupling between the two fibers.
KINZ-CG02 is a miniature connector
For connecting duplex POF cables to point sensors. The special sensor design based on POF allows system engineers to avoid any galvanic contact between the arc flash area and the detection electronics.
Both KINZ-CG01 and KINZ-CG02 are part of a comprehensive arc inspection product portfolio. In combination with sensor transceivers, they are designed to detect arc flash events in electrical grids.
