Questions And Answers

Greetings.

Question 1) Can human body becomes statically charged with the influence of electrical field? example are, walking beneath an overhead high tension power cable, walking near a T.V monitor or a high voltage transformer.

Question 2) Tribocharge - why isn't any voltage field detected on the conductor when the conductor is rubbed with a insulator ?

Thank you
 

Can a person have a charge induced on them? My guess would be yes, but this is not our area of expertise. We do have many years of experience in electronics manufacturing ESD control and we have not encountered this question in electronics manufacturing.

Conductors can tribocharge. When there is contact and separation between a conductive surface and an insulative surface, charge generation will occur.

Per ESD-ADV1.0 Glossary Triboelectric Charging “The generation of electrostatic charges when two materials make contact or are rubbed together, then separated.”

Per ESD Handbook TR20.20 section 2.4 Sources of Static Electricity “Theoretically, any two items or materials brought into contact and then separated can liberate static electricity.”

Per section 5.5.5 Tribocharging “Tribocharging from equipment can be caused by conveyer belts, hardware sliding on surfaces, and moving fluids (sprays) or solids (sandblasters). Moving gases that are free of particulates, e.g. from air guns, fans, or heat guns do not tribocharge an insulator or conductor. If rapid air movement causes parts or dust particles to rub together, tribocharging might occur.”
