Do not obstruct air inlet openings. Do not obstruct
discharge openings. Coolant flow must reach these
openings. If t
he generator is exposed to harsh
environmental conditions, the generator can be
modified in the fieldinordertoaddfilters and
space heater
s. In addition, a more rigid periodic
maintenance schedule should be established.
Electrical Measurements
Measure the i
nsulation resistance of each winding
if the generator was exposed to the following
conditions:
•
Rapid changes in temperature
•
Freezing
•
Wet climate during shipment
•
Wet climate during storage
Note: These
tests should be conducted prior to any
power connections that are being made. These tests
should be conducted prior to any control connections
that are bei
ng made.
Refer to the Generator Maintenance section of this
manual in or
der to measure the following items:
•
Exciter field (stator)
•
Exciter armature (rotor)
•
Generator
field (rotor)
•
Generator armature (stator)
Alignment
After the generator set has been placed in the final
position, the generator must be aligned. Refer to
these publ
ications:
•
Special Instruction, SEHS7654, “Alignment -
General In
structions”
•
Special Instruction, SEHS7259, “Alignment of
Single-Be
aring Generators”
•
Special Instruction, REHS0177, “Alignment of the
Close Cou
pled Two-Bearing Generators”
Protective Devices
The output to th
e load of the generator should always
be protected with an overload protection device such
as a circuit breaker or fuses. Fuses should be sized
by using the lo
west possible current rating. However,
this rating must be above the current rating for full
load. A common recommendation is 115 percent
of rated curr
ent. Determine the size of fuses or
determine the size of circuit breakers in accordance
with NEMA, IEC, and Local Electrical Codes.
