Limitation reactor / current

MRI reactors are used to limit the inrush peak current
to less than 100 times the rated current of the bank of
capacitors.
The inrush current peak is due to the transitory pheno-
mena of high amplitude and high frequency that are
generated when the bank of capacitors cuts in on the
supply network; this peak is considerably accentuated
when a bank of capacitors is inserted in parallel with
other banks that are already energized.
The reactors are single phase with an air core and copper
winding. They are set in series with the bank of capaci-
tors. They can be made for either indoor installation (see
figure A1) or outdoor installation (see figure A2).
The reactors must be installed on post insulators with an
insulation class equal to or greater than that of the bank
of capacitors, considering the minimum distances for
the installation indicated in the figure W.
