SKM SYSTEMS ANALYSIS

SKM Systems Analysis, Inc. is a California-based corporation founded in 1972 by three progressive engineers with a desire to automate electrical design calculations. They originally developed the DAPPER power system analysis software on a mainframe at the UCLA Computer Center. By 1978, DAPPER was running in time-share mode on the Control Data Corporation mainframe, and being used by engineers both in the United States and internationally. The first PC version of DAPPER was released in 1981, foll... owed in 1983 by the CAPTOR time current coordination software. A_FAULT was developed in 1988 and IEC_FAULT in 1991, to provide ANSI and IEC-909 fault calculations, respectively. The dynamic simulation program I*SIM and the harmonic analysis program HI_WAVE filled out the DOS-based product line in 1992. In 1995, SKM released Power*Tools for Windows (PTW) - completely built from ground up using the latest Windows development tools. The new Windows PTW line of software offers the same powerful studies that have been available in DOS, but adds greater flexibility, enhanced ease of use, and graphical functions not available in DOS. PTW was first released in December 1995 with the base DAPPER and CAPTOR modules. A_FAULT, IEC_FAULT and TMS were added the following year. HI_WAVE was added in 1998, I*SIM in 1999, and the Device Evaluation module in 2000. The Ground Grid, Reliability and Single-Phase/Unbalanced 3-Phase studies were all added in 2001. Throughout the development process, the PTW interface has continually expanded and improved, to provide maximum flexibility and ultimate ease-of-use.More
