Arc light protection optical fiber

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 to solve such problems?

Arc protection at the speed of light:

Protect people and equipment

• Technology and overcurrent detection

• To reduce the likelihood of injury

• Reduces arc incident energy levels by up to 88%

• To increase safety and minimize equipment damage

• Safely detect arc flash by using a combination of light sensors

• Install into new systems or retrofit into existing equipment for everyone

• Detect arc events and send trip signals in as little as 2 ms

Benefits of Arc Flash Protection

1. High speed trip:

Relays reduce the risk of arcing by reducing overall troubleshooting time.

2. Reduce accident energy:

The faster the arc flash event disappears, the lower the incident energy. The relay detects an arc flash hazard and sends a trip signal to the circuit breaker within 2 ms.

3. Improve security:

Arc-flash detection reduces fault clearing time, reduces arc-flash hazards, and improves safety. To verify arc-flash protection performance, a series of tests were conducted in a high-current laboratory. During these tests, the arc flash

Using technology, incident energy levels were reduced by 88%.

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 dis

Above is the switchgear contactor after a 5 kV arc flash event, during which conventional overcurrent protection was applied. Damage requires replacement of contactors, fuse clips, copper busses, cables, control wires, disconnects and hardware.

Shown here (before any cleanup is done) is the inside of a switchgear protected by SEL light sensing and overcurrent protection during a 6.6 kV arc flash event. Damage is limited to arcing on the cable termination bolts.

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.

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.
