Scope

This standard is a basic safety publication, mainly used by technical committees in accordance with IEC Guide104 and ISO /IEC Guide51
The principle of writing standards.
This standard is not used as an independent standard.
According to IEC Guide104, technical committees need to use basic safety publications such as IEC 61140 when drafting, revising or revising their publications.
This standard applies to electric shock protection for humans and livestock. Its purpose is to give the common electrical installations, systems and equipment, or between them
Basic principles and requirements for cooperation. Regarding the voltage or current value or type of current, this standard does not limit, and the frequency is required to not exceed 1000Hz.
Some clauses in this standard involve low and high voltage systems, devices and equipment. The rated voltage of the low voltage of this standard does not exceed AC
1000V or 1500V DC. The rated voltage of high voltage exceeds AC 1000V or DC 1500V.
It needs to be pointed out that in order to effectively design and select protection measures, it is necessary to consider the possible voltage types and waveforms, that is, AC or DC
Voltage, sine, transient, phase control, superimposed DC, and possible hybrids of these waveforms. The device or equipment may affect the voltage wave
Shape, such as a converter or frequency converter. The current under normal and fault conditions depends on the above voltage.
