Principles of Capacitor Measurement Capacitors are essential components in electronic circuits, commonly used to store electric charge. The measurement of a capacitor’s value is based on the physical concept of capacitance, which is the ability of a system of two conductors separated by an insulator (dielectric) to store charge. The capacitance value is influenced by factors such as the dist...
Dual Nature of Electrical Power Electricity is an indispensable resource in modern society, playing a crucial role in our daily lives and industrial activities. However, electricity also poses potential dangers. Electrical leakage and current leakage can threaten personal safety and even cause fatal accidents. Therefore, ensuring electrical safety is a critical issue that must be addressed. What i...
Principle of Common Mode Chokes Common mode chokes (CMCs) are highly effective in dealing with common mode interference signals. Their working principle includes: • Common Mode Interference: When common mode interference current passes through a common mode choke, the magnetic flux direction in both coils is the same. This increases the total inductance rapidly due to coupling, presenting a lar...
Introduction to Impulse Coils Tester Impulse coil testers, also known as digital interturn insulation testers, are devices used for non-destructive electrical testing of coil-wound components. The operating principle involves applying the same pulse voltage to both a standard coil winding and the coil under test, then comparing their transient waveforms to evaluate the quality of the tested coil. ...
XRF (X-ray Fluorescence) analyzers are commonly used analytical devices capable of quickly and non-destructively determining the composition of various materials. XRF analyzers excite the elements in a sample using X-rays, causing inner-shell electrons to transition to higher energy levels and emit secondary X-rays (X-ray fluorescence). These fluorescent X-rays are then used for elemental analysis...
