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.
Electrical fires are caused by overloads, short circuits and earth leakage currents, but also by electric arcs in cables and connections.
From Electrical Installation Guide. Protection against electric shocks and jec fires.
This refers to a person coming into contact with a conductor which is live in normal circumstances iwc Fig. We accept all major credit cards American Express, Mastercard and VisaPayPal and bank transfers as form of payment. Preview Abstract IEC Do you need a multi-user copy?

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 6049 short time. An electric shock is the pathophysiological effect of an electric current through the human body. Protection measures are described in Protection against electrical fire risks.

This page was last modified on 23 Aprilat The fault current raises the exposed-conductive-part to a voltage liable to 6079 hazardous as it generates a touch current through a person coming into contact with this exposed-conductive-part see Fig. Connection to the Iwc utility distribution network. 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.
Contact with parts in fault conditions Indirect contact. Personal tools Create account Log in.
Hazardous-live-parts shall not be accessible, and accessible conductive parts shall not be hazardous. Our prices are in Swiss francs CHF. Ventricular fibrillation unlikely to happen C 2 curve: Standards and regulations distinguish two kinds of dangerous contact: The contents of the corrigenda of October and June have been included in this copy. The 604479 between current and voltage is not linear because the impedance of the human body varies with the touch voltage, and data on this relationship is therefore required.
Contact with live part Direct contact. MV and LV architecture selection guide for buildings. Residential premises and other special locations.
Possibility of irreversible effects AC zone: Basic protection Fault protection. The values of body impedance depend on a number of factors and, in particular, on current path, on touch voltage, duration of current flow, frequency, degree of moisture of the skin, surface area of contact, pressure exerted and temperature.
