Capacitor technical knowledge, principles and fundamentals
AC high voltage ceramic capacitor are mainly used in AC voltage work situations, such as power testing equipment, national grid equipment, etc. AC high-voltage ceramic capacitors have high requirements for various indicators of the capacitor, and generally require the following parameters: 1. AC working voltage; 2. Lightning impulse voltage; 3. Partial discharge level; 4. Temperature change [...]
For some purchasers and engineers, when purchasing Snap-in aluminum electrolytic capacitors, they don’t know much about Snap-in aluminum electrolytic capacitors and don’t know how to judge the quality of Snap-in aluminum electrolytic capacitors. Our company summarizes the following customers often encountered A few points: 1 Voltage and capacity of Snap-in aluminum electrolytics capacitor; Undoubtedly, the voltage [...]
High frequency capacitors are basically composed of passive components, active devices and passive networks. The frequency characteristics of components used in high-frequency circuits are different from those used in low-frequency circuits. Passive linear components in high frequency circuits are mainly resistors (devices), capacitors (devices) and inductors (devices). Features of high frequency capacitors: 1. High-Q C0G series [...]
parallel capacitors is a kind of reactive power compensation equipment, usually high-voltage centralized compensation is used to compensate the reactive power on all circuits and transformers on the power supply side of the low-voltage busbar of the substation. In use, it is often combined with on-load tapping transformers to improve the power quality of the power [...]
The difference between series and parallel capacitors is: different composition, different current paths, and different disconnection. 1. Different composition 1. Series connection: Series connection is to connect the components one by one. 2. Parallel connection: Parallel connection consists of connecting components in parallel. Two, the current path is different 1. Series connection: In the series circuit, [...]
