Harmonic Analysis

Power Quality Analysis

The Power Quality Audit (PQA), is a service offered by Influx Power that checks the reliability, efficiency and safety of an organization’s electrical system.

The PQA uses network analysers, instruments specially designed to detect faults and deteriorations and record parameters and information that may be of use in locating the causes of electrical disturbance.

The data is collected and analyzed by Influx Engineers, who can then diagnose the problems and suggest the most appropriate solutions.

Harmonic Analysis :

This includes the usage of computer programs to recognize and forecast possible harmonic problems and reduction methods.

Detail scope of PQ study includes

• Site surveys, on-site power quality data logging and harmonic analysis.

• Detailed study of reactive power, power factor and existing harmonic pattern in the system.

• Simulation of electrical networks and systems and carrying out harmonic penetration studies.

• Solutions to improve power factor and mitigate harmonics as per IEEE 519 standards.

• Implementing the recommended solutions and verifying the results by doing re-analysis to ensure optimized system performance with fastest payback

• Installation, programming and commissioning of harmonic mitigation equipment such as active and passive harmonic filters.

• Design & recommend optimal solutions based on measured data
