Abstract :
Low frequency common mode voltages can produce malfunction of control and measuring systems. The sources of common mode voltages are electrical equipment, semiconductor converters and secondary supply units. Common mode voltage can be more than 140 V on output of secondary supply units with transformer and more than 30 V on input terminal of frequency converter.
