Power Quality

Electric power quality, or simply power quality, involves voltage, frequency, and waveform. In other words, good power quality is about creating a perfect power supply that is always available, has a pure noise-free sinusoidal wave shape, and is always within voltage and frequency tolerances. However, increasing and varying energy demands from different loads and equally varying generation from energy sources, all impose disturbances on the grid, making deviations from these ideal conditions happen more frequently than ever.

We have experience from projects in the following areas among others:

  • UPS – Uninterruptable Power Supply
  • Low harmonic drives
  • PFC – Power Factor Correction frontends
  • Active harmonic filters
  • Passive harmonic filters
  • Utility grid monitoring and data logging
  • STATCOM – Static Synchronous Compensator
  • SSW – Static transfer switches
