applications with its electromechanical SPDT dry contact relays, now CSA-rated for 5 amps. The relay response time is now less than 100 milliseconds and the deadband can be set from 1 percent to 100 percent of the input spans for added flexibility to prevent false trips. The alarms accept input signal ranges of 0 to 20 mA dc and 0 to 1, 5, 20, 50 or 500 V dc. Models come with one or two relays for single- or dual-setpoint alarms that are adjustable for up to 115 percent of the input span. The al
The Northwest Power Group, which provides electricity for the northwest portion of the People`s Republic of China, plans to purchase a digital microwave-radio system from Harris Corp. The new system will transmit telecommunications signals including data, voice and video. Northwest Power Group plans to utilize the system to continue its expansion in the northwest region.
Dispatching for an electrical utility during power outages is one of life`s most difficult tasks. For most individuals whose job it is to handle telephones, dispatch crews and generally facilitate the restoration of electrical service, life is made up of long periods of normalcy liberally interspersed with periods of intense activity.
Remote power outage system from Scientific-Atlanta is designed to detect power outages in a home or business and automatically place a call to the utility and a customer or designated third party. The system also allows utilities to send a broadcast message to notify groups of customers of special circumstances and estimated time for power restoration.

CH-Analysis is an off-the-shelf application, written in a standard language, designed to be integrateable into all GISs. Leverages existing technology by using front and back end of the utility`s GIS.
New, high-intensity, wide-angle LED lamps in red, amber and green are designed to replace the most common, slide-based incandescent bulbs used in control panels. DDP 24L4 X1 will work in the GE ET-5, ET-6 or Westinghouse Minalite sockets.
New software automates electronic distribution of mapping databases. It makes data available to mobile and office workers for utilities with automated mapping systems. Data Bridge provides tools for extracting and transferring maps and related data for distribution to desktop and mobile PC users. It is designed to access intelligent mapping systems such as FRAMME or Byers EWO on a UNIX or PC file server.
Autodesk GIS market group has introduced AutoCAD Map which integrates mapping and GIS technology into AutoCAD. It offers accurate map creation and maintenance for AutoCAD users who need to create, view, present and distribute maps.
