August 30, 2012 — Battle Ground, WA — Delta Computer Systems, Inc. announces that it will be exhibiting the second generation Step and Touch safety monitor at the iP Safety Conference held in Vancouver, WA during September 25-27, 2012 . The event is the utility industry's leading education event for safety, training and operations professionals.

The SNT was an innovation of the Bonneville Power Administration to improve worksite safety for line crew personnel. The BPA and Delta worked together to design this sealed, battery-powered, voltage monitoring and alarming instrument that has been helping ensure the safety of BPA line crews since 2003. The second generation SNT-02 Kit has been enhanced based upon field experience and now includes the practical, field-proven instrument and improved accessories in a rugged enclosure for easy transport, setup, and use.

De-energized lines that are bonded to equipotential ground system can pick up induced energy from parallel lines. This electromagnetic coupling can result in dangerous voltages if the ground system is poor (high resistance). Known as Ground Potential Rise, this safety hazard is particularly dangerous since it can change rapidly due to factors such as drying soils, varying power levels on adjacent lines, and circulating currents due to multiple ground connections. The SNT-02 instrument continuously monitors for Step and Touch potential, and provides visible and audible alarms, improving job site safety.

SNT-02 kit (above) includes the SNT instrument, ground rod with slide hammer, clamps and other accessories.

The SNT-02 continuously monitors for and warns against Step and Touch voltages, improving job site safety. "The need for this capability has become more important over the last decade as more power corridors have increased in complexity - often driven by growth in green energy", stated Steve Nylund, CEO of Delta Computer Systems. "The BPA, contractors and investor owned utility customers have found the SNT to be very valuable and Delta is pleased to bring this product to the general market." Nylund added.
