Installation of generator
General provisions for installation
Important
y
A cooling air feed above 40 °C can lead to power restrictions;
in extreme cases it can cause damage to the generator.
►
The temperature of the supplied cooling air should not
exceed 40 °C.
►
Observe the necessary minimum clearances.
6.3
General provisions for installation
The basic requirement for safe, reliable and fault-free operation, electrical
and mechanical safety is a technically and materially correct installation of
the generator.
Generally the generators run clockwise. In this case, the output voltage has
a “clockwise field of rotation”. Dual-bearing generators can also be operated
in anticlockwise rotation; the rotary field of the output voltage then switches
to “anticlockwise rotation”.
y
The drive system must have sufficient power reserves for the dynamic
processes when switching electrical consumers on and off. Its control
system must have reliable command over these processes.
Important
y
Single-bearing generators are damaged if operated in an
anticlockwise direction of rotation.
►
Never drive single-bearing generators in the anticlockwise
direction of rotation.
►
Before commissioning, ensure the direction of rotation is
correct.
