Working principle of Current and voltage transformer LJB1 2000A/10V 0.5
Current and voltage transformer LJB1 2000A/10V 0.5 is an instrument that converts large primary current into small secondary current according to the principle of electromagnetic induction. Current transformer is composed of closed iron core and winding. Its primary winding turns are very small, and it is in series in the line of the current to be measured.
Therefore, the current and voltage transformer LJB1 2000A/10V 0.5 often has all the current of the line flowing through, and the secondary side winding turns are relatively large. The current and voltage transformer LJB1 2000A/10V 0.5 is connected in series in the measuring instrument and protection circuit. When it is working, its secondary side 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.
The current and voltage transformer LJB1 has the following options:
current and voltage transformer LJB1-1A/10V
current and voltage transformer LJB1-1000A/10V
current and voltage transformer LJB1-800A/10V
