What is an electrical surge?

Surge is a type of electrical noise that collectively refers to impulses of high voltage and high current. Instantaneous transient surges have extremely high amplitude currents, voltages, and electromagnetic fields. The energy waveform in the form of an impulse and oscillatory waveform, including inductive and capacitive properties with a very high voltage peak and rapid rise time, and a very fast and short repetition period, can be used within 0.5 Hz for commercial power and It refers to an electrical waveform that is superimposed on signals, data, communication lines, etc. and flows in very quickly.

 

 

What causes an electrical surge?

As a natural phenomenon, surges occur when overvoltage and overcurrent are generated by direct lightning strikes to structures, equipment, and power lines, and high currents are indirectly conducted and introduced into communication and power systems by lightning strikes. Opening and closing of inductive loads in power systems (high-voltage circuit breakers, disconnectors, etc.) or large industrial equipment switches. Relay. It is caused by the arc of a welder, the opening/closing surge caused by a short circuit, the operation of a motor, an elevator, etc. A surge is caused by EMP, which artificially generates and radiates powerful electromagnetic waves, instantly destroying or malfunctioning the electronic components of advanced weapons.
