Simulations
Solutions to power quality problems require accurate network analysis using reliable simulation software.
HARMONIZER performs studies of both low and high voltage networks with regard to:
- Harmonic resonances
- Effects of installing harmonic generating loads and filters
- Overloading of transformers, capacitors and other loads
- Network harmonic impedance
- Coupling transients
- Transient stresses in switches and across the insulation of cables, support insulators, capacitors, etc.
