Analysis Software

EDSA Micro Corporationcs Analysis program is designed to assist electrical engineers in solving harmonics problems. Using any network created for analysis, the program is capable of performing Frequency Scan, Total Harmonics Distortion (THD) and Telephone Interference analysis along with automatic filter sizing, tuning and placement. The software is capable of calculating the impedance frequency responses (Frequency Scan) of all buses with respect to a harmonics source at a given location (bus) and with respect to positive, zero or negative sequence network to identify possible resonance situations. The Frequency scan can be plotted in Ohms or Per Unit, phase angle in degrees. It can also calculate bus voltage THD for all buses, and branch current THD for all branches of a power system when a harmonics source, or several harmonics sources are presented. Branch current RMS values and transformer K-factors can be obtained. The simulation results are presented in time-domain waveform and in frequency-domain spectrum. They can be displayed in text or graphic formats.
