What happens inside a surge protector during a lightning strike?

What Happens Inside a Surge Protective Device During a Lightning Strike?During a lightning strike, surge protective devices (SPDs) play a crucial role in protecting electrical equipment from transient overvoltages (i.e., surges). Below are the main processes and mechanisms that occur inside an SPD during such events:1. Surge Detection and ResponseWhen a surge caused by a lightning strike enters the power system, the surge protective device quickly detects this abnormal voltage. Typically, SPDs h

What is a fixed capacitance?

What is a fixed capacitance?

1. DefinitionWhat is commonly referred to as a "permanent capacitor" is likely a popular term. Strictly speaking, it may refer to a fixed capacitor. A fixed capacitor is a type of capacitor with a constant capacitance value. In a circuit, its capacitance will not change due to normal voltage, current variations, or other common external conditions. Its main functions include storing electrical energy, filtering, coupling, and bypassing.2. Structure and PrincipleStructureTake the common ceramic c
