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. Do you need a multi-user copy?
Our prices are in Swiss francs CHF. Energy Efficiency in electrical distribution. 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.
Protection against electric shock – Electrical Installation Guide
The necessary criterion is the admissible limit of touch voltage i. You may select the license of your choice.
Contents 1 – Introduction 1. Basic protection Fault protection. Contact with live part Direct contact.
Possibility of irreversible effects AC zone: This refers to a person coming into contact with a conductor which is live in normal circumstances see Fig. This page was last edited on 14 Octoberat 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 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.
Protection against electric shocks and electrical fires. The contents of the corrigenda of October and June have been included in this copy. Views Page Talk View source History.
The timestamp is only as accurate as the clock in the camera, and it may be completely wrong. Contact with parts in fault conditions Indirect contact.

This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it.
Connection to the LV utility distribution network. Log-log graph of the effect of alternating current I of duration T passing from left hand to feet as defined in IEC publicationredrawn by CMG Lee based on http: Chapter – Protection against electric shocks and electric fires. The fundamental rule of protection against electric shock is provided by the document IEC “Protection against electric shock — Common aspects for installations and equipment” which covers both electrical installations and electrical equipment.

You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use. Protection measures are described in Protection against electrical fire risks. Standards and regulations distinguish two kinds of dangerous contact: Views View Edit History. Residential premises and other special locations.
The following test report forms are related: An electric shock is the pathophysiological effect of an electric current through the human body.
Characteristics of particular sources and loads. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file.
