i think its static electricity.
1500v From ESD Association ESD Handbook ESD TR20.20 section 5.3.2.1: "When people are charged with static electricity, they can release stored energy to conductive objects such as doorknobs and electronic circuits. This transfer of energy is called an electrostatic discharge. Sometimes the electrostatic discharge causes visible sparks, but more often, it is both unseen and unfelt. Electrostatic discharges can damage ESD sensitive components used in modern electronics. Static electricity is a natural phenomenon that occurs in all climates and at all levels of relative humidity year round. Most people cannot feel an electrostatic discharge unless the static voltage is greater than 2000 volts. However, some electronic circuitry can be damaged by ESD that is less than 2000 volts. The damage can be done without people having any sensation of the ESD event. When a wrist strap is worn properly and connected to ground, the person wearing it will stay near ground potential."

Alternating current of gradually decreasing amplitude which, under certain conditions, flows through a circuit containing inductance, capacitance, and resistance when a voltage is applied is known as Oscillatory discharge.
Automated machine tools are more commonly known as numerically controlled (NC) machine tools.
A sequence of characters is an array of type char, commonly known as a string.
static electricity
Esd is known as electrostatic discharge. Humidity plays a role in electrostatic discharge because it makes it harder for an object to hold an electric charge.
There are many different types of electrostatic discharge. Some examples include electric sparks such as from lightning, corona discharge, and brush discharge.
Electrostatic discharge
A transistor
When there is a sufficiently strong electrostatic charge, it can cause air molecules to ionize, which are then electrically conductive and create a pathway for the discharge of the electrostatic charge.
Static discharge is the spark associated with static electricity that is caused by electrostatic discharge.
grounding strap
That might refer to a lightning.
Frightening lightning
Frightening Lightning
They are shoes that are made to dissapate ElectroStatic Discharge which can damage electronics and computer parts.
