HVD1
High Voltage Disconnect
Module
Most electrical generators do not
have a means of preventing a
disastrous over voltage condition
from occurring that could destroy the
generator and or the load that it is
connected to.
The generator relies on a voltage
regulator to control its voltage and
all
voltage regulators will eventually fail in
one of three ways: No voltage, erratic
voltage or the worst of all, high and
uncontrollable voltage. Sometimes
grounded exciter fields will cause high
and uncontrolled voltage.
The
HVD1 High Voltage Disconnect
Module
is specifically designed for
protection from high voltage conditions
on voltage regulated generators. It is
universal and can be used with most
brands and types of voltage regulators
found in the industry today.
The HVD1 is installed in the incoming
voltage supply of a voltage regulator and
when the generator voltage exceeds a
preset voltage set point, it
instantaneously disconnects the power
to the regulator, which causes the
generator voltage to collapse. Once the
HVD1 has been activated by high
voltage, it can only be reset by pushing a
mechanical pushbutton located on its
disconnect relay.
