Parents of children with autistic spectrum disorders are particularly strongly opposed to testing linked to termination and fear it would lead to greater discrimination and less support for them.

PRMF relative phase spectrum IP method with PRMF signal as excitation has the same advantage of relative phase IP method, and offer rich information for the discrimination of anomaly source.

A new method, based on the analysis of frequency spectrum of instantaneous power, for the discrimination between internal fault currents and inrush currents in transformer is proposed.
