Voltage transformers and current transformers
Aug 06 , 2020
In order to accurately measure the power consumption in high-voltage and high-current AC circuits, voltage transformers and current transformers are generally used to convert high voltage into low voltage and large current into small current, and configure a moderate meter to use voltage Transformers to carry out accurate measurements. For example, the current, working voltage, output power, frequ...

Inductor selection analysis, let's understand together
Feb 27 , 2021
You should be clear about the scope of inductance in the power circuit. Since the inductance is mostly not stable during the entire working period of the components, it is particularly important to grasp the scope of the effective value. For inductors used in power switching applications, the overall goal of allowable harmonic distortion current and transient response will determine the inductance...

Between short circuit and open circuit, these two transformers have different taboos
Mar 13 , 2022
Everyone knows that voltage transformers cannot be short-circuited, and current transformers cannot be open-circuited. Once the voltage transformers are short-circuited or the current transformers are open-circuited, they will destroy the voltage transformers or cause risks. In terms of structural design, we all know that both voltage transformers and current transformers are all transformers, but...
