Electricity's Invisible Reach: Why Maintaining Safe Distances is Crucial

  • Did you know that electricity can jump through the air, especially in humid conditions? This phenomenon is called an electrical arc. 
  • Arcs can travel significant distances, making seemingly safe areas suddenly dangerous if they are near high-voltage power sources. 

Why are Arcs Dangerous?

  • Jumping the Gap: Contrary to what we might think, electricity doesn’t need direct contact to be dangerous. Under certain conditions, like humid environments, air becomes a conductor, allowing arcs to travel significant distances. This means even seemingly safe areas near high-voltage equipment can become electrified. 
  • Invisible Threat: The invisible nature of electricity and the speed of arcs make them especially dangerous. You might not see, hear, or feel the danger until it’s too late. 
  • Devastating Effects: Electrical arcs can cause severe burns due to the intense heat they generate. Additionally, the spark can ignite surrounding materials, leading to fires. 


Detecting electrical hazards in the air requires a compact, lightweight device which can detect hazard without contact. The small and portable nature of such devices enables efficient monitoring from a safe distance, preventing potential risks associated with electrical currents. Utilizing these compact devices enhances the ability to identify hazards promptly and take necessary precautions without compromising the well-being of individuals or equipment.
