Product Specification

Harmonic System for Industries:
During the last years there has been a large modernisation of the industrial production processes and a fast evolution in power electronics, especially in the field of power converters such as variable speed drives for DC motors, frequency converters, USP... All these equipments have a common characteristic which is the generation of harmonics currents that reduce the quaility of the electrical energy.

Naac completes its range of filtering inductors with a range of electromagnetic harmonic eliminating devices named Compensators. The functioning of these devices is based on the cancellation and compensation of magnetic fluxes. The main advantage of the Compensators in the absence of electronic components and capacitors. The Compensators are therefore maintenance free, have an extramely long lifetime compared with other types of filters and are compatible with any electrical installation.

Problems:

Malfunctioning and failure in electronic equipment.
Overheating and failure in transformers and cables.
Overload and failure in capacitor banks.
Low efficiency of transformer and cables.
Tripping of protections without apparent reason.
Interferences in communication networks.

Causes:

Low quaility electrical energy. Elevated harmonic distortion in the voltage.
Notches and transients in the voltage caused by power converters.
Elevated harmonic distortion in the current.
Resonance in capacitor banks.
Elevated true RMS current in the phases.
Low power factor due to harmonics.

Harmonic Compensator H2OF:
The H2 Of series Compensator achieves the highest protection level for industrial installations. An elevated level of filtering of the 5th, 7th, 17th, and 19th harmonic is obtained in combination with galvanic isolation of the entire load. In order to obtain in combination with galvanic isolation of the entire load. In order to obtain a correct filtering it is necessary to install as well a RTL line inductor with each DC converter or frequency converter. The H2OF Compensator consists of two secondary windings. Each secondary should supply 52 % of the load to be filtered. All harmonics are compensated in the secondary windings and do not circulate through of the electrical installation.

The H2OF provides additional advantages such as: reduction of electromagnetic disturbances, optional voltage adaption between input and output and the possibility use independence earths, as the neutral is isolated from the mains.
