A load detection technique for a load comprising multiple frequency-dependant sub-loads comprises measuring a representation of the impedance characteristic of the load; providing stored representations of a multiplicity of impedance characteristics of the load; each one of the stored representations represents the impedance of the load when at least a particular one of the sub-loads is in a fault condition; and comparing the measured representation of the current impedance characteristic of the load with each one of the stored representations and in case that the measured representation matches a stored representation, identifying the sub-load or sub-loads being in a fault condition by the corresponding stored representation
