Other Factors Causing Overvoltages

a) Electrical Switching Incidents

Instantaneous voltages causing electrical switching incidents are very common and considered a significant interference source. The current flowing through a conductor creates a magnetic field around it, and the magnetic field suddenly decreases when the current is cut (switch is on). The energy accumulating on the conductor is distributed through induction as instantaneous overvoltage. 

b) Network Peaks

No matter how solid the infrastructure is, due to non-compliance of the production or energy transfer lines with some international standards, and static load negations occurring in the areas it flows through, OSB transformers that feed hundreds of factories in the regions where companies or institutions using this energy are located generate peaks against instantaneous loads.

c) Network Harmonics

Harmonics is the most talked about power quality problem in recent years and has various disruptive effects on many different facilities. Electronic card failures are one of the effects of harmonics. Condensers inside the parasite filter found in the card leads might also draw over-current and explode. When it comes to card failures of critical loads such as CNC benches, the financial burden of this problem becomes serious.
