- Analysis of the ratio of consumed active and reactive energy (cos φ)

- Development of engineering solutions for controlling cos φ, when it is necessary (if photos are available) - an active and capacitive cos φ

- Development of a short-acting cos φ  - Regulators (thyristor control)

- Analysis of the presence of harmonics and provide solutions for their compensation

- Monitor for proper load distribution by phases

- Monitor the voltage level
