[vc_row][vc_column][vc_column_text]Coil is a more frequently used equipment in power circuits. It is made by winding a transmission line on an insulating tube. The material of the transmission line will endanger the function of the coil. Below I will tell everyone what are the elements that harm coil inductance and what is the function of coil…
[vc_row][vc_column][vc_column_text] The power factor correction (PFC) circuit and inverter circuit in the telecom rectifier and server power supply unit (PSU) all need to detect the current signal on the high-voltage side to the controller on the low-voltage side, so an isolated current sensor is used. There are many ways to implement isolated current detection, such…
A general current transformer can transform a primary current with a large value into a secondary current with a smaller value according to a certain transformation ratio, so as to play the main purpose of maintenance and accurate measurement. The main function of the zero-sequence current transformer is to protect the power circuit when an…
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,…
What is the role of the current transformer? It is a device that transforms a large current into a second small current, and then displays the information on the second small current according to the secondary display information table, and you can understand the measured current. Carefully observe the current in each phase to see…
Current Transformers are generally used in the maintenance process of high-current lines. After applying current sensor, the ultra-high current can be converted into a low voltage that is not harmful to us, so that we can carry out safety measurements. The key role of curent transformer is to reduce the large current of the current…
