EL-DR DISCHARGE REACTOR

40E.003-60003

The increasing demand for shorter discharge periods cannot
be satisfied by traditional discharge means (fixed resistors).
The installation of additional fast discharge resistors at the
capacitor contactor results in an increase in material and in-
stallation costs. Our discharge reactor replaces the compul-
sory fixed resistors and additional rapid discharge resistors,
and at the same time it reduces the heat dissipation losses
inside the capacitor bank. It further avoids additional heating
of the capacitor terminals by standard discharge resistors.
Discharge reactors must NOT be used in combination »!« EL-DR DISCHARGE REAC-
with thyristor switches. Frequent switching and the
charging function of many switches will damage the
reactor. TOR
