Thermal capacity of liquid resistance started motor

[thehoover]

How would I calculate the Kjoule thermal capacity for a rotor starter.

Rotor current=1805A
Rotor Voltage = 1335V
Stator voltage= 11000V
Stator current=243.1A
Motor rating 4000kW
3 phase Y
cos 0.89
Starting torque 200%

Since kJoule=kWattsecond, the time needs to be given or estimated. Some idea about the motor prospective acceleration curve would help.

The run up time for the liquid resistance starter is 10 seconds.
