Site safety systems around power lines
Made signal-detection products for utility and construction work keep operators safe by monitoring the fields and electrical phenomena around medium and high-voltage electric lines
Every year, many on-site accidents occur because of the proximity of high-voltage electric lines causing injuries, sometimes fatal Made combines engineering and design expertise in electronics, telecommunications, signal treatment, and computer science for producing signal-detection products for industrial fields such as construction and utility work

CD based 'Hazardous Area' training course released
Abhisam Software has just released a new CD based training course on Hazardous Area Instrumentation: this is available as either a stand alone single user license or as a multi-user license
Since the company start-up in 1991, it has collaborated with the French national electric company, EDF, to develop, test, and validate its products in real environment.
Two of its benchmark products for signal detection will be at the ICUEE 2007 trade show from 16 to 18 October in Louisville, Kentucky: these will be SkyRadio for overhead high-voltage line detection on construction sites, and the Nadir system for pre-identifying live low-voltage cables and feeders for electrical utility work.
Designed for use on construction sites, the Made SkyRadio system helps detect high-voltage electrical lines overhead.

At ACHEMA, demand on the part of exhibitors remains stable: exhibitors will only just fall short of the record numbers at ACHEMA 2000, thus making it the second best result in its history
It includes one-to-eight wireless sensors on the high point of the equipment, such as the boom on a concrete pump, and corresponding transmitter/receiver modules that communicate with the central processing unit.
The sensors measure the electrical field around a medium or high-voltage line and, if a sensor is inside a risk zone (within 3 meters for a medium-voltage line; within 5 meters for a high-voltage line), the system indicates which sensor is "at risk" by a visual and audible signal to alert the operator.
This system is also available for smaller machines like aerial lifts, or scissor lifts.
When working in trenches with many cables, electricity-utility workers need to quickly and correctly identify cables to make sure they are working on the right ones.
The Nadir system has two components to identify live low-voltage cables under load in a trench or substation exit.
A transmitter is connected using crocodile clips between two phases, or between a neutral phase downstream from the point of interest.
The transmitter signal does not disturb communications systems.
The second component, the hand-held receiver, incorporates a display for signal-level readout and push-button controls connected to a transducer for cable identification or to a flexible Rogowski coil for phase/core identification.
In addition to SkyRadio and Nadir, Made produces a wide range of products for use with concrete/construction work, electrical utilities, and gas utilities.
