Longer period of time without human contact with dangerous voltage electric shock

In electrical technology, electronics technology, everyday life and electronic production process, often referred to or used in safety voltage , many textbooks define the voltage does not exceed 36V safe voltage . This kind of definition is scientific, safe voltage is absolutely safe , most of these problems are even some electricians, electrical  Voltage stabilizer could not say . In order to ensure "safe voltage " security , the author in the form of questions and answers will be safe voltage and its related knowledge are described below. Definition of safe voltage  power transformers  , also known as safety extra low voltage, is the body a long time without contact with dangerous voltage electric shock , that the human body tissues and organs ( such as the skin, heart , respiratory and nervous system ) will not cause any damage to the voltage , ie voltage does not endanger the safety of  electric meter  . It should be particularly emphasized : in any case , are not safe voltage can be understood as absolutely no hazardous voltages . Which depends on the degree of danger of electric shock shock after the degree of risk factors, mainly on the amount of current through the body , current duration , current flows through the body's way , the body's resistance , the power frequency , the body's health status, sex , age, etc. factor. These factors are interrelated , as long as certain factors reaches a certain level , will make those who suffer an electric shock hazard.
