The thesis focuses on the measurement of touch current on electronic devices. The applicable standard is IEC 62368-1: Audio/video, information and communication technology equipment – Part 1: Safety requirements, which in detail refers to IEC 60990: Methods of measurement of touch current and protective conductor current.
The first part of the thesis provides a theoretical description of touch current and explains why it occurs. It describes the procedures used for testing and what factors influence the measured values.
The practical part of the thesis presents the procedure for measuring touch current on a power supply unit. It also describes the necessary measuring equipment and its preparation.
The device mentioned in the thesis exceeds the permissible limit values of the measurements. However, the manufacturer follows additional instructions in case these values are exceeded, so the device passed the testing.
