Overload protection (49)

The overload function protects the stator winding against

thermal overload. The thermal stress of the stator can be
supervised by means of a thermal image, which can be

calculated from the standard heating expression according to
IEC 60255-8:

where:

τ

I

= generator heating and cooling time constant

ln = natural

logarithm

Ip = preload current (corresponds to the heating

level reached)

k

= factor for allowed continuous overload

I

GN

= generator rated current

The heating time constant (

τ)

and the load current factor (k)

corresponding to the maximum thermal load are adjustable.
The cooling time constant of the thermal overload protection is
the same as the heating time constant.
The thermal overload stage is provided with a separately
adjustable alarm function, the setting range of which is

60...100% of the thermal trip level.
