SINAF 2.0 ACTIVE FILTER
Description
The SINAF 2.0 active filter is equipment designed to solve the faults which may occur in a three or four wires, three phase installation. It includes the following functions:
Harmonic filtering.
Phase current balance.
Power factor correction.
This is the ideal solution for installations with a large amount of single-phase and three-phase loads generating harmonics such as computers, UPC, lights a lifting equipment.
The SINAF 2.0 filter allows the selective removal of harmonics using the configuration of its DSP controls. SINAF corrects both the existing third harmonic component in neutral and the unbalanced current itself at 50 Hz achieving practically neutral currents (3 phases/4 wires).
Connecting the SINAF 2.0 filter must be in parallel with the loads to be corrected. The filter can operate in three wire systems (with or without neutral).
The correction capacity of the SINAF 2.0 is expressed as the RMS current value. The available capacity may be used for any three functions: filtering, balancing or correcting reactive. The SINAF has two different correction capacities:
RMS current which the equipment is capable of injecting into phase conductors
RMS current which the equipment is capable of injecting into the neutral conductor, regardless of the phase.
The available correction capacity in the conductor is 1.5 times the phase capacity. This allows systems with high third harmonic content to be corrected.

Harmonic Filters
These filters are used when the main objective is not the reactive power compensation at the fundamental frequency, but to reduce the harmonic distortion in the supply system.
Among the problems caused by harmonics and which may make their suppression necessary, are the following:
Interferences in telecommunications.
Distortion on the mains voltage.
Disturbances in electronic systems.
Erratic operation of control and protection relays .
Failures in transformers and motors, due to overheating caused by losses on the core.
Overheating of protective fuses to the point where a minor spike on the line causes them to blow.
It should be pointed out that the impedance of all the filters is capacitive below its tuning frequency, whereby they also contribute, even if in a small scale, to the reactive power compensation at the fundamental frequency.
Installation of filters produces a modification on the topology of the electrical supply system. For this reason, the design of filters must be done with regard to an accurate analysis and study of the whole system.
According to the application, there are different types of filters:
3rd harmonic filter HBF-T
Isolation filter
Absortion filter HAF
High pass filter HPF
Active filter SINAF 2.0
