Abstract

An electric appliance (100) is disclosed. The electric appliance has an electric load (205), and a driving element (215) for selectively energizing/de-energizing the electric load (205). The driving element (215) has a first driving terminal (A₁) coupled to a first load terminal (T₁) of the electric load, a second driving terminal (A₂) coupled to a first power supply terminal (T_N), and a control terminal (G) for switching on/off the driving element (215) thereby allowing said selective energization/de-energization, respectively. The electric appliance also has a switching element (230) for selectively coupling a second power supply terminal (T_L) to a second load terminal (T₂) of the electric load (205). The electric appliance (100) further has a detection arrangement (210,220) configured for detecting a first electrical quantity (V_A1) at the first driving terminal (A₁), and at least one between a second electrical quantity (V_T2,CL,V_T2,OP) at the second load terminal (T₂) and a power supply electrical quantity (V_MAINS) at the second power supply terminal (T_L). The detection arrangement (210,220) has a coupling element (220) coupling the first driving terminal (A₁) to the second load terminal (T₂), and a control unit (210) coupled to the first driving terminal (A₁), and to at least one between the second load terminal (T₂) and the second power supply terminal (T_L). The control unit (210) is further configured for determining dispersion of electric power towards ground in the electric load (205) according to the detected electrical quantities.
