Kec example of differences between parameters used for calculations is the assumed resistance for the victim: I am used to IEC standards, so IEC is the reference for current-duration limits, distinguishing between perceivable intensity, peripheral muscular effects, more serious effects, e.

I read an article about research into a possible electric weapon that would shock someone on the scale of nanoseconds to stun them without risking killing them. Search all products by.

This standard only considers conducted current resulting from the direct application of 6049-2 source of current to the body, as does IEC and IEC They also specify on which current level a circuit breaker for leakage to ground RCD, residual current protective device shall trip: 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.
This refers to a person coming into contact with a conductor which is live in normal circumstances see Fig. In reality, a short pulse has a high frequency content, so at a first approx the expected behavior is similar.
The protection of persons against electric shock in LV installations must be provided in conformity with appropriate national standards, statutory regulations, codes of practice, official guides and circulars iex. Personal tools Create account Log in. Home Questions Tags Users Unanswered.
If those answers do not fully address your question, please ask a new question. This refers to a person coming into contact with an exposed conductive-part which is not normally live, but 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 coming into contact with this exposed-conductive-part see Fig.
I imagine that’s a bit complex to determine, but otherwise is there a duration for which a normally deadly amperage would shock someone but not cause a heart attack? IEC For short ice the standard indicates the energy as the main factor to determine if fibrillation may occur. Like is there a reasonably consistent relationship between current duration through the body and relative danger?
Preview Abstract IECwhich is a technical specification, describes the effects on the human body when a sinusoidal alternating current in the frequency range above Hz passes through it.

Relevant IEC standards include: The values specified are deemed to be applicable for impulse durations from 0,1 ms up to and including 10 ms. Protection measures are described in Protection against 604799-2 fire risks. Connection to the MV utility distribution network.

It does not consider current induced within the body caused by its exposure to an external electromagnetic field. Basic protection Fault protection.
