A new version of DAPPER (Distribution Analysis for Power
Planning, Evaluation, and Reporting) can handle transient motor
starting analysis, allowing you to predict the effects and
power dropoff of an electrical system when a large motor
starts. DAPPER is a set of programs for the design and analysis
of industrial and commercial distribution power systems.
 
According to SKM, DAPPER 3.4's Concurrent interface provides a
two-way communication channel between it and any CAD program
that accepts a DXF transfer file. DAPPER 3.4 produces load
schedules and generates automatic one-line diagrams. It can
handle feeder and transformer sizing, load flow, and fault
studies. It generates reports for three-phase, single line to
ground, line to line, and double line to fault duties. You can
scroll through windows and organize information with a project
manager.
 
DAPPER 3.4 runs on the IBM PC XT with 640K bytes of RAM, any
graphics adapter, and a hard disk drive.
 
Price: DAPPER 3.4 for 100 nodes, $3950; for 300 nodes, $6395.
