What is three-phase alternating current? Presumably most of the friends engaged in the electrical industry are not strange, but for a beginner it may be half understood. In fact, three-phase alternating current is a form of power transmission, referred to as: three-phase electricity. General household electricity is single-phase AC, but the large-scale production and distribution …
The experimental circuit is as follows: Components and parameters: Resistors are RJ14 type resistors with an accuracy of 0.1%, R1=100kΩ, R2=R3=10kΩ, R4=12kΩ, R5=3kΩ. There are two sets of capacitors for comparison: one is a CB4 type capacitor with a high Q value, with a capacity of C1=C2=14.66nF and Q>20000. The other group is the common …

Lightning arrester is an electrical device that can release lightning or release the power system operating overvoltage energy, protect electrical equipment from instantaneous overvoltage (lightning overvoltage, operating overvoltage, power frequency transient overvoltage impact), and cut off the continuous current, and do not cause system grounding short circuit. The role of the lightning arrester: The lightning …
Overvoltage action counters are crucial components of power system protection and monitoring. Their role extends beyond merely recording voltage events exceeding normal ranges; they also assist operators in identifying issues and taking measures to ensure the reliability and stability of the power system. This article delves into the working principles, application areas, functions, and the …
