Thermal unit equations
Cooling at normal load or during standstill:
When the current falls below 1.0 x l , the thermal curve A is linearly
brought down to the level of the thermal history curve B as shown in curve part C.
This corresponds to the levelling out of the hot spots in the motor.
Thereafter the cooling follows the lower curve with a time constant
equal to the heating time constant as long as the motor is running at normal load or idling.
For a motor at standstill, i.e. when the current is below 12% of l , the cooling can be expressed as:
Q=Q02 x e -t/kc x , where Q0 is the initial thermal level and kc is the cooling time multiplier.
In the equations above, the heating time constant can be substituted by
32 x t6x.
The thermal unit is supervised twice a second in the relay, giving a maximum trip time
resolution of 0.5 s.
