The E-lert device can be used by Linesmen, Electricians, Maintenance workers and machine operators to alert of unsafe proximity to sources of electricity. The device is integrated to a hard hat and alerts when the user is within the exclusion zone of H.V. electrical conductors. The device uses patented sensing technology to analyse electrical fields and determine hazardous proximity. The device is designed to complement existing methods of isolation and testing of electrical apparatus by providing a ready indication while working should the supply be unexpectedly energised.
The Safety E-lert is clipped into a JSP AZ/NZS1801 compliant hard hat, without affecting the normal usability of the helmet.
The device uses an inductive sensing circuit and a smart filtering circuit which filters unwanted interference from radio frequency and other sources, minimising nuisance alerts. Patented technology looks for sources of 50hz and 60hz, indicating presence of power. The sensor is designed to activate from 5Kv at a distance of 2 metres.
