What type of voltage can cause nuisance shocks to workers at ground level?

Capacitive coupled voltage is a type of voltage that can lead to nuisance shocks for workers at ground level due to its ability to transfer energy through capacitive coupling. This phenomenon occurs when there is a voltage difference between two conductors separated by insulation or air, creating a capacitance effect that can allow a small voltage to be present on a non-energized object. Workers at ground level may inadvertently touch these objects, resulting in a mild shock sensation.

This type of shock does not typically result from direct contact with a live conductor but is instead caused by the capacitive coupling of electrical fields, which can occur in environments where there are high-voltage lines or equipment nearby, increasing the risk of these nuisance shocks. Understanding this concept is critical for ensuring workplace safety and implementing adequate measures to minimize the risk of exposure to such voltages.

In contrast, static electricity involves charge build-up on surfaces and typically produces shocks that are sudden and isolated, rather than a continuous nuisance. Inductive voltage refers to the voltage generated by the magnetic field around a current-carrying conductor, primarily affecting nearby conductive materials rather than causing direct shocks at ground level. High-frequency voltage is less common in industrial applications and more associated with specific electronic devices, making it less likely
