-    Interruption of high-current arcs

 

-    Role of high-current technology in the economic way of design of electrical equipment

-    Design and operation of test transformers. Generation of high alternating voltages by oscillating circuit

 

-    Effects of current in the human body: heat, mechanical, electrochemical effects and paralysis. Role of current, frequency and time, allowable limits.

-    Effects of electric and magnetic fields. Laboratory tests on animals and humans. Epidemiologic inspections.

-    Induced current in the human body. Direct effects of electric and magnetic fields.

-    Contact with metal objects in electromagnetic fields.

 

-    Calculation of electric field around high voltage power lines. Measurement of electric and magnetic fields.

-    Ionizing and non-ionizing radiations. Heat effects of non-ionizing radiations. Direct harm caused by the photon of ionizing radiations. Description of doses. Equipment of measurement.

The main aim of the subject is to introduce the latest techniques of calculation and measurement of high voltage and high current, which is the basis of the economic and safe operation of many electrical equipment. This is the theoretical and practical principle of the reliable operation of grids – with a voltage level of a few hundred kilovolts and nominal (or fault) current of a few kiloamper – the insulators, or the connectors and mounting units.
