From production downtime to penalties on the bill, the effects directly involve operating costs and loss of competitiveness.
Voltage and frequency variations outside the regulatory limits affect your installation’s operability and safety.
› Damage to electronic equipment and PLCs
› Unplanned service interruptions
› Reduced productivity
› Increased repair costs
Inductive or capacitive reactive energy reduces efficiency and generates increasing monthly surcharges on the electricity bill.
› Penalties on the electricity bill
› Increased current in lines
› Power transformer saturation
› Reduced network capacity
AC/DC converters generate harmonics that distort the network, causing overheating, insulation failures and interference.
› Overheating of conductors and motors
› Unwanted tripping of protections
› Premature capacitor deterioration
› Shorter useful life of LED lighting
To optimise your installation, you need to act on both the energy you receive and the energy you consume. Circutor offers certified solutions for both dimensions.
Analyse the parameters of the power supplied by the distributor: voltage, frequency, harmonics, flicker and quality events as per EN 50160 and IEC 61000-4-30 Ed.3.
Measure and correct the problems caused by your own loads and generators: current and voltage harmonics and interharmonics, inductive and capacitive reactive energy consumption, voltage fluctuations (flicker) and current and voltage unbalances.
Class A certified analyzers as per IEC 61000-4.30 Ed.3 with automatic reports according to the EN 50160 standard, guaranteeing reliable data for decision-making purposes.

› Harmonics up to the 50th order with selectable frequencies
› Inductive and capacitive reactive energy compensation
› Balancing of two-phase currents in three-wire networks
RECOMMENDED USE
Passive reactors and filters
Passive solution for stable loads such as motors with frequency converters. Especially suitable when the current is constant and the variability is minimal.
› LCL filter: THD(I) < 5% in 6-pulse converters
› LRZ up to 63A · LRBZ up to 600A
› LRZ/LRBZ: reduces THD from 40–50% to ~20%
› Complies with EN 61000-4-3 and IEEE 519 standards
› Installation on the mains side or load side of the transducer
RECOMMENDED USE
Reactive energy is essential for motors, transformers and coils to operate, but an excess of this energy leads to increasing penalties on the bill and losses in the distribution lines.
Compensating the reactive energy reduces circulating currents, unloads lines and transformers and eliminates monthly surcharges due to low power factor.
› Direct reduction in the energy bill
› Unloading of lines and transformers, lower losses
› Voltage regulation and stabilisation in the installation
› Reduction of CO2 emissions due to lower kVA demand
