Electric as well as diesel-electric locomotives and multiple units (EMU/ DEMU) require multifold monitoring and control of electric energy. Voltage and current sensors used for this purpose need to meet the special demands posed by railway operations. Of particular concern are are and smoke protection, electrical safety, as well as robustness towards extreme environmental conditions, mechanical stress and EMI infuences.
