The Function of Current Transformer of Silent Diesel Generator Set

Feb. 21, 2023

Silent diesel generator sets can be installed with current transformers to detect the output current through electricity meters. Silent diesel generator sets can be divided into two categories: AC silent diesel generator sets and DC silent diesel generator sets. Current transformer also includes AC current transformer and current transformer, which can only be installed on AC silent diesel generator set. Both AC and DC current transformers can be used, so both AC and DC silent diesel generator sets can be installed.

Working principle of current transformer: The working principle of current transformer is based on the principle of electromagnetic induction. Current transformer is composed of closed iron core and winding. Its primary winding turns are small, and it is connected in series in the line where the current needs to be measured, so it often has all the current of the line flowing through. The secondary winding turns are large, and it is connected in series in the measuring instrument and protection circuit. When the current transformer is working, its secondary circuit is always closed, so the impedance of the measuring instrument and protection circuit series coil is very small, and the working state of the current transformer is close to short circuit. The current transformer is used to convert the large current at the primary side into the small current at the secondary side for measurement. The secondary side cannot be opened.


Function of current transformer: The main function of current transformer is to convert the large current in the AC circuit into a certain proportion of small current (5 amps in China's standard) for measurement and relay protection. In the process of power generation, transformation, transmission and distribution, due to different electrical equipment, the current often varies from tens of amperes to tens of thousands of amperes, and these circuits may also be accompanied by high voltage.


In order to monitor and measure the circuits of these lines, and at the same time to solve the dangers caused by high voltage and high current, current transformers are needed. The clamp meter used by electricians is a kind of equipment used to measure AC current. Its "clamp" is a through-type current transformer.
