Internet of Things (IoT) isn’t just about flashy gadgets. Affordable modules, networks, and technology offer innovative and cost-effective new systems in the backend and infrastructure that can protect properties and human lives.

South Korean startup Nare IoT Lab’s Prevention System for Electrical Arc Fires is one such example that will be on the rise. Nare’s system can distinguish between a harmless electrical arc and a dangerous arc that can cause fires in livestock farms.

Protecting livestock from arc fires

An arc fault is a high-power discharge of electricity between two or more conductors. Conductors, which are supposed to be isolated from each other, can meet due to damage to wires or loose connections, common in outdoor settings such as livestock farms.

The discharge translates into heat, which can break down the wire’s insulation and possibly trigger an electrical fire. According to the National Fire Data System run by South Korea’s Ministry of Public Safety and Security, out of 42,135 fires in the country in 2014, 22 percent were caused by electricity. Out of the 9,445 fires caused by electricity, 76 percent were caused by arc faults.

Nare’s ArcLow module detects the formation of arcs. If it deems the arc to have high heat –enough to cause fire — it sends a warning to the owner’s smartphone, and he or she can choose to turn off the power grid in the area where the arc has formed. An alarm also goes off in the area, and each incident is saved on a big database for future reference.
