Have you ever experience the scenario as below:
You reach for your car’s door and experience an electric
shock!
It is actually the release of electrical energy developed on
your body by actions or movement prior to touching of that door. The charge may
be generated by a simple action such as walking across a road. The electrical
shock that is experienced occurs when the body loses its stored energy very
rapidly in the form of a spark.
Last month, I’ve been to Shanghai for 6 days to witness the
Factory Acceptance Test (FAT) for escalators. This query had been raised up and
the supplier shows us on how the escalators cancelling the electrostatic
charge.
Below is the video
The brush will touch the step plate and will discharge the
electrostatic charge generated by moving step plate to ground.
Therefore, all of us can feel safe when using escalator....enjoy😍
