A system for monitoring operation of a retarding grid associated with a traction motor of a machine includes a pressure sensor and a temperature sensor for measuring atmospheric pressure and temperature in real time. The system further includes a controller that determines a current air density on the basis of the measured atmospheric pressure and temperature. The controller then determines a threshold retarding power limit for the retarding grid on the basis of the current air density; and a threshold torque limit for the traction motor on the basis of the determined threshold retarding power limit and a current wheel speed of the machine. The controller determines a current retarding torque at the traction motor, and selectively generates a warning signal to an operator of the machine on the basis of the threshold torque limit determined for the traction motor and the current retarding torque at the traction motor.
