PRODUCT


EN-GTF Series
summary
Active filter through the matching CT, real-time tracking and monitoring of the current load in the current and through the integration of the matrix SPD calculation, analysis of the harmonic load. The signal is transmitted to the IGBT by PWM, and the control inverter device generates a reverse current with the same direction as the core load harmonics, which is sent back to the grid. Implementation of the power grid in the harmonic offset, to filter out the purpose of harmonic.

Technical characteristics
