Document Type and Number:
Japanese Patent JP2004538493
Kind Code:
A
Abstract:
The invention relates to a device and a method for monitoring the connection of an electrical supply unit comprising voltage detection ( 32 ) detecting phase voltage ( 14 ), current detection ( 32 ) detecting phase voltages ( 38 ), a transformation unit ( 66 ) transforming the phase voltages ( 38 ) after conducting field-oriented regulation in at least one cross current ( 62 ), wherein a monitoring device ( 34 ) is provided to monitor at least one supply connection ( 28, 36 ) by means of which an electrical supply unit ( 32 ) is supplied, said monitoring unit evaluating the variation of the cross current ( 62 ) in order to monitor the connection.
