phenomenon; According to the figure of the transformer model, capacity and impedance match,third, the insulation resistance determinationThe two terminals of the broadcast line are disconnected, and the insulation resistance between the wires is measured with a 500V meter. The measurement project is: wire and wire and wire and ground insulation resistance, insulation resistance is generally not less than 0.5mω, for each circuit resistance should be carried out in the sub-loop measurement, the m

It is the most important management area of the wiring system, and all floors are transmitted by cable or fiber optic cable. Typically, this system is installed in the mainframe room of computer systems, network systems, and program-controlled system computers. 3) Vertical Backbone subsystem It connects communication rooms, equipment, an

, complexity or the tenacity of optical cables, you may consider using the 5e shielded copper cable solution. Even a simple layer of aluminum foil shielding, in the correct grounding can also provide a significant ability to resist electromagnetic/RF interference. The correct grounding is the key to obtain effective shielding. Grounding method ungrounded or gro

1 : no function is provided in the circuit. It is only for convenience of debugging or Compatibility Design on the PCB. 2 : Jumper can be used. If a line is not used, do not paste the resistor directly (without affecting the appearance) 3 : when the matching circuit parameters are uncertain, use 0 ohm instead. during actual debugging, determine the parameters, then, it is replaced by a component of a specific value. 4. when you want to test the current consumption of some circuits, you ca

Single Point Grounding (Protection grounding, working grounding, DC grounding are separated from each other on the equip

a great impact on the suppression of higher harmonic waves. 3.1.1 The Third Harmonic circulation in the D-junction winding can generate the Third Harmonic Magnetic Potential in the transformer, which is balanced against the third harmonic magnetic potential of the Low Voltage Winding; 3.1.2 The Third Harmonic Potential of the high-voltage phase winding is in the central flow of the D-junction loop. The third harmonic current can form a circulation in the first winding of the D-junction so that

the access devices that collect and distribute electric energy. They determine the number of devices in the Power Distribution Device and indicate how to connect generators, transformers, and lines, and how to connect to the system to complete the transmission and distribution task.9. Current Transformer: The instrument converter is an instrument that converts large current into small current.10. Transformer: a static electrical device used to change the AC voltage of a certain value to another

installation of component bodies perpendicular to the circuit board. The advantage of welding is space saving. Horizontal refers to the parallel installation of components closely related to the circuit board and welding. Its advantage is that the mechanical strength of component installation is good. For these two different installation elements, the component hole distance on the printed circuit board is different. (3) The grounding point of the sa

phenomenon of probe burning occurs. This is because most of the oscilloscope's "signal common line" terminals are connected to a protective grounding system, often referred to as "grounding". The result is that all of the signals that are applied to the oscilloscope and provided by the oscilloscope have a common connection point. This common connection point is typically an oscilloscope enclosure that conn

It is the primary management area of the cabling system, and data on all floors is transmitted by cables or optical fiber cables. Generally, this system is installed in the host room of the computer system, network system, and NC control system. 3) Vertical trunk SubsystemIt connects communication rooms, equipment rooms, and entry de
