HI_WAVE Study Module
HI_WAVE simulates resonance and harmonic distortion in industrial, commercial, and utility power systems. 
Harmonic current and voltage sources may be defined at multiple locations in the power system. Capacitor banks, single tune filters and high pass filters may be included in the voltage and current distortion evaluation, impedance resonance scans, and in harmonic load flow results. 
Any type of system design, with any combination of voltage levels may be evaluated with this highly interactive, user friendly software. 
With HI_WAVE, new power systems may be examined before they are built and the harmonic effects addressed during the design. Existing power systems may be studied and corrective filter designs evaluated before they are installed. Every bus and branch in the power system may be quickly evaluated for harmonic content and for resonant impedance characteristics.

A downloadable version of the HI_WAVE brochure is available in PDF format via a link at the bottom of this page.

  • Save time and money by trouble-shooting harmonic problems and evaluating alternative solutions quickly. 
  • Improve power system reliability by identifying potential resonance conditions and minimising harmonic distortion. 
  • Minimise I2R heating losses and increase equipment life. 
  • Save money and improve designs by predicting resonance, distortion and filter effectiveness before the system is built.
