The Transient Network Analyzer (TNA) is a collection of miniature models used to simulate the effects of switching events on power systems and to study various electromagnetic transient phenomena. This paper describes how a new microcomputer is used to serve as a high performance data acquisition system for TNA operations. The system provides high-speed, synchronous acquisition of multi-phase voltage and current waveforms as well as control of circuit breaker closing angles for statistical analysis. The computer interfaces with the TNA by means of plug-in boards containing analog-to-digital and digital-to-analog converters. The user interface is implemented with a graphical programming environment to provide controls and indicators on a front panel similar to those found on an oscilloscope. Application of the new technology to the system make it a compact, highly flexible, and powerful tool.
