    Hello,

    You could try to measure the current in the power transistors.
    That should give an idea about the power used.

    Or you can just add a circuit breaker or fuse to open the circuit on overload.

    So...what's your circuit?

    The circuit topology is important in determining the best short circuit protection scheme.
