3.1 earth fault current current flowing to earth due to an insulation fault
(SOURCE: IEC 60050-442:1998. 442-01-23]
3.2 residual current 1 RMS value of the vector sum of the currents flowing through the main circuit of the residual current device
(SOURCE: IEC 60050-442:1998. 442-05-19, modified — in alignment with the use in this document. The symbol has been modified.)
3.3 rated residual operating current An fault current for which the residual current is designed
3.4 residual operating current a value of residual current which causes the residual current device to operate under specified conditions
(SOURCE: IEC 60050-442:1998. 442-05-20, modified — The symbol has been added.]
3.5 leakage current electric current in an unwanted conductive path to earth under normal operating conditions
(SOURCE: IEC 60050-195:1998, 195-05-15, modified — to earth has been added and the deprecated term “earth current” omitted.)IEC 61557-6 pdf free download.
