Retrieved from ” http: This refers to a person coming into contact with a conductor which is live in normal circumstances see Fig. From Electrical Installation Guide.
Standards and regulations distinguish two kinds of dangerous contact: MV and LV architecture selection guide for buildings. I, the copyright holder of this work, hereby publish it under the following licenses:.
Possibility of irreversible effects AC zone: When a current exceeding 30 mA passes near the heart of a human body, the person concerned is in serious danger if the current is not interrupted in a very short time.
The different parts of the humanbody such as the skin, blood, muscles, other tissues and joints present to the electric current a certain impedance composed of resistive and capacitive components.

Protection against electric shock – Electrical Installation Guide
An electric shock is the pathophysiological effect of an electric current through the human body. The necessary criterion is the admissible limit of touch voltage i. The following test report forms are related: Our prices are in Swiss francs CHF.

This refers to a person coming into contact with an exposed conductive-part which is not normally live, 64079 has become live accidentally due to insulation failure or some other cause.

The fault current raises the exposed-conductive-part to a voltage liable to be hazardous as it generates a touch current through a person ic into contact with this exposed-conductive-part see Fig. Relevant IEC standards include: Contents 1 – Introduction 1. Hazardous-live-parts shall not be accessible, and accessible conductive parts shall not be hazardous.
Characteristics of particular sources and loads. The impedance values indicated in this technical specification result from a close examination of the experimental results available from measurements carried out principally on corpses and on some living persons.

How to contribute Play with sandbox Recent changes Help. Protection measures are described in Protection against electrical fire risks. Residential premises and other special locations. The degree of danger for the victim is a function of the magnitude of the current, the parts of the body through which the current passes, and the duration of current flow.
