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...
An impedance analyzer is a specialized electronic instrument used to measure the impedance characteristics of electronic components, circuits, and material elements. It is capable of characterizing the impedance of devices and materials over a range of frequencies, making it suitable for applications in various fields including material science and electronic circuit design. Operating Principle Th...
The electric wire and cable burning tester is a precision instrument specifically designed to determine the non-propagation of flames of cables under fire conditions. This equipment is suitable for various cable types including single plastic wires, control cables, cross-linked cables, elevator cables, ship cables, and mining cables. Additionally, it can conduct vertical burning tests for high sel...
The spectrum analyzer is a high-precision instrument specifically designed for measuring the spectral characteristics of electrical signals. By converting signals into spectrum graphs, users can visually understand the signal’s spectral density and conduct in-depth signal analysis based on frequency distribution. Operating Principle At the core of a spectrum analyzer lies the principle of Fo...
Principle of Operation of the Leakage Tracer Tester The operation principle of a leakage tracer tester primarily involves insulation quality testing and leakage current testing of electrical equipment: Insulation Quality Testing: In insulation quality testing, the leakage tracer tester applies a specific voltage (often several times the rated operating voltage) to the insulation structure of the d...
