Arc Fault Detection

  There are many different forms of electrical fires, and today fires initiated by short-circuits, leakage currents, or lightning can be prevented thanks to circuit breakers, earth leakage protection devices and surge protection devices.

With all this protection there remains a significant threat from fires generated by electrical arcs in localised wiring. Commonly caused by a damaged cable or a poor connection, things like pulled-out sockets, cables squashed under furniture, and loose junction boxes may generate dangerous electric arc faults - causing fires.

Arc detectors monitor branch circuits to lower the electrical fire risk. Unlike anti-fire systems (smoke detectors, extinguishers, etc.) acting after the fire begins, arc detectors are designed to trip before cables or sockets experiencing arcing ignite.

This technology was developed more than 15 years ago for the North American market. Protection that has been mandatory in the USA for over 10 years has recently been added to European as well as Australian and New Zealand standards, although not yet mandated for use. Proven in the USA, these are the latest form of technology in New Zealand when it comes to fire protection in the home, and it is predicted they will become a mandatory device in the future.

Arc detectors are installed and wired in switchboards just like any other electrical protection device, and prevent electrical fires that were previously impossible to detect until too late.
