Power Quality

Power quality directly affects the reliability, efficiency and lifetime of electrical equipment. Harmonics, voltage variations and transients can cause overheating, insulation stress, malfunctions and premature failures.

Power quality analyser connected to a low-voltage switchboard

EWP provides power quality analysis and measurement services to help you identify problems, understand their root causes and put effective improvements in place.

Simulation and network studies

We carry out harmonic studies and network calculations to evaluate distortion levels and their impact on transformers and connected equipment.

On-site measurements

On-site power quality measurements capture real operating conditions and reveal anomalies that theoretical analysis alone cannot detect. Our analysis covers:

  • Harmonic distortion and resonance phenomena
  • Voltage and current variations under normal and disturbed conditions
  • Transient events: slow, fast and very fast transients

When needed, we also carry out special measurements, including non-electrical quantities, to understand complex phenomena affecting system performance.

From analysis to solutions

Based on the issues identified, we define practical mitigation strategies: system configuration changes, filtering solutions or operational improvements, to restore acceptable power quality and protect critical assets.
