Issues that need to be paid attention to and handled in the power supply system:
▷ Overvoltage:
Overvoltage refers to the situation where the power supply voltage exceeds the rated voltage of the equipment. Long-term overvoltage may cause damage to the components inside the equipment, such as capacitor breakdown, insulation aging, etc., which may shorten the service life of the equipment or cause failures.
For example, in some areas, due to grid voltage fluctuations or lightning strikes, the power supply voltage may rise instantly and exceed the tolerance of the equipment.
▷ Undervoltage:
Undervoltage refers to the situation where the power supply voltage is lower than the rated voltage of the equipment. Undervoltage may cause the equipment to fail to work properly, and even damage the equipment in some cases.
For example, when the grid voltage is unstable or the power supply is insufficient, the equipment may shut down or fail due to Undervoltage.
▷ Surge/spike:
Surge or spike voltage refers to the phenomenon that the power supply voltage rises rapidly in a short period of time and exceeds the normal value. This voltage fluctuation is usually caused by switching operations in the grid, lightning strikes, or sudden changes in large loads.
Surge/spike voltage is very harmful to the equipment. It may instantly break through the insulation layer of the equipment, causing equipment damage or fire and other safety accidents.
▷ Power return surge:
Power return surge refers to the instantaneous high voltage generated by the release of stored energy in inductive components (such as transformers, inductors, etc.) when the power system is suddenly powered off or switched.
This high voltage may damage other components in the power system, such as rectifier diodes, capacitors, etc., and may even cause damage to the entire power system.
In order to ensure the safe and stable operation of electrical equipment, devices such as voltage protectors can be used to prevent damage to equipment caused by overvoltage, undervoltage, and surges/spikes.
