The protective monitoring system receives signals from the fault sensing components in the generator
output circuit and functions to cause the load to be disconnected from the generator if an abnormal
condition of voltage, frequency, or load develops.
b) Voltage Regulator
A microprocessor-type, adjustable voltage regulator provides automatic voltage regulation at the
aircraft. The regulated out is also adjustable for a variety of output cable sizes and lengths.
