Power Quality Measurement

The proliferation of electronically controlled drives has led to an increased utilization of non-linear receivers in electrical systems. Non-linear receivers introduce impulsive power consumption, resulting in voltage distortions within the electrical system—commonly known as harmonic distortion. While total harmonic distortion is a significant aspect, it is only part of the broader power quality issue.

Various factors contribute to poor energy power quality. A thorough analysis of electrical parameters provides crucial insights into whether machinery is being supplied with “clean” energy. Power Quality Analysis emerges as an invaluable tool for decision-making during new installations, replacement of malfunctioning machines, or the evaluation of existing configurations.

Power Quality evaluation involves on-site measurements conducted by the crew, industry personnel, or our service engineers. Our diagnostic centre scrutinizes the data for unusual events, assessing power quality in alignment with association guidelines, classification limits, and electrical best practices.

Through power quality monitoring, we can identify and address:

• Power interruptions
• Undervoltage and overvoltage
• Sags and swells
• Flickering and transient conditions
• Unbalance and Power Factor
• Harmonic distortions (THD)

Additionally, we gather vital information about voltage regulators, such as the speed at which they restore nominal voltage after the activation of large consumers. This comprehensive approach ensures a thorough understanding of the energy supplied to machinery, enabling informed decisions for optimal performance and longevity.
