How is ground resistance measured?

  • Four-Terminal Method: The tester carries out the measurement using four electrodes (the ground electrode under test, the auxiliary current electrode, and the auxiliary voltage electrode).

  • Current Injection: The tester injects a current of a certain frequency into the ground through the auxiliary current electrode.

  • Voltage Measurement: The voltage drop caused by the current is measured through the auxiliary voltage electrode.

  • Resistance Calculation: The ground resistance value is calculated based on the measured current and voltage drop.

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?
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
