Abstract

Dispositivo circuitale per verificare il corretto funzionamento di una protezione elettrica, in particolare di un interruttore differenziale e del collegamento della linea di terra in un impianto elettrico caratterizzato dal fatto che prevede un'impedenza inseribile fra linea di fase e linea di terra e dimensionata in modo da determinare una corrente verso terra tale da provocare l'intervento dell'interruttore differenziale.
