features |
Apply to 3P3L system, filter was connected among three phase of power
grid, it is suited to power system with or without neutral line, it can filter
none-zero frequency harmonics, compensate reactive power and phase
unbalanced. |
Apply to 3P4L system, can filter
the harmonic through phase and
neutral line, include zero sequence
