The aim of power quality audits is therefore to monitor the interaction between the electrical system and the load system. This interaction must be considered in terms of the quality of the power supplied to the loads and the impact of the users on the supply system. On the one hand, electricity consumers are buyers of electricity of a certain quality, but on the other, the Customer’s own loads can impact negatively on the electricity system, and are therefore also subject to evaluation in terms of quality.
Harmonic pollution can also disturb equipment and compromise its performance, thus giving rise to the following problems:
• Sovratensioni e/o sovracorrenti nella rete elettrica
• Overvoltages and overcurrents in the electrical network
• Overheating of cables, transformers and generators
• Reduction of energy efficiency
• Overheating of electronic equipment
• Tripping of circuit breakers and protection relays
• Malfunction of control systems
• Voltage distortion and consequent power factor variation
• Damage to power factor correction units caused by resonance
• Imprecision of measuring instruments
• Interference in telecommunication systems
• Neutral overload
• Generation of braking torque in rotating machinery
• Premature ageing of electrical equipment
• Poor performance of inverters in photovoltaic systems, resulting in reduced production efficiency.
Cesit Ingegneria s.r.l. is a dependable consultant capable of performing power quality analyses and at the same offering the following targeted services:
• Voltage and current waveform deformation analysis (DC offset, harmonics, interharmonics, notching and noise)
• Monitoring of slow voltage variations (undervoltage, overvoltage, prolonged interruptions, fluctuations)
• Measurement of voltage asymmetry
• Monitoring of rapid voltage variations (voltage sags, voltage swells, interruptions)
• Monitoring of voltage and current transients
Thanks to the many years’ experience of its technical personnel, Cesit Ingegneria s.r.l. can also give you the right guidance for resolving possible problems, by adopting appropriate countermeasures or installing components and devices for eliminating disturbances, such as:
• Filtri passivi, attivi e ibridi per armoniche
• Passive, active and hybrid filters for harmonics
• Power factor correction filters for reactive power compensation
• Static VAr compensators (SVCs)
• Saturable reactor fault current limiters (FCLs)
