In America’s biggest cities, hundreds of manholes catch fire or explode every year, with the consequences ranging from serious injury to fatality. Even in the UK, more than 50 incidents a year are reported according to statistics supplied by the UK Health and Safety Executive.
Overhead power lines are used to transmit and distribute electrical power across long distances, forming a power or national grid. Steel tower structures, pylons or wooden poles suspend electricity-carrying conductors across a range of operating voltages.
UK engineering and design consultancy, Plextek has been working with US-based CNIguard to develop a new IoT-based system to prevent manhole explosions, primarily caused by bad weather and flooding interacting with aging underground power infrastructures.
Con Edison innovates to protect public safety and reduce manhole explosions in New York City by deploying CNIguard’s Sentir remote sensoring system using the alias SOS (Structure Observation System).
Drones are un-piloted aircraft or missiles controlled by an operator from the ground. They were originally designed for military reconnaissance purposes, away from the public eye.
Regions that regularly or seasonally experience temperatures below the freezing point of water will have their roads treated with halite, more commonly known as rock salt.
Most gases fall into one or more categories of inert, flammable, oxidizing, toxic or cryogenic. Those that are classified as inert or reactive generally don’t undergo chemical reactions under particular conditions and include nitrogen and argon.
Stray voltage appears where there is electric potential between two objects that would normally not have any voltage difference between them. Metallic electrical equipment enclosures or street furniture may possess large voltages due to a variety of faults in the electrical distribution system.
Gas sensors are available in a variety of technologies, each having distinct advantages and limitations for their individual applications. Some of the more common types are electrochemical, catalytic bead, infrared and metal oxide. CNIguard’s Chief Technology Officer, Ian Courtney, examines the relative merits of the different gas sensors available.
Narrowband IoT (NB-IoT) is a category of low power wide area networks (LPWA) designed to support the deployment of Internet of Things (IOT) devices. The specification was developed by the Third Generation Partnership Project (3GPP), consisting of seven telecommunications standard organizational partners.
