Transformer grounding resistance

The neutral grounding resistance is used to reduce the system fault current, thereby protecting the safety of system equipment and maintenance personnel. When the neutral point is directly grounded, the fault current of the system is only affected by the soil impedance. At this time, the fault current will be very high, which will damage the transformer, generator, motor, circuit and other system equipment. The neutral point grounding resistance is connected between the neutral point and the ground to increase the resistance of the line when the grounding system fails, so as to control the fault current at a safe level.

The types of electronic loads are different, and there are certain differences in their roles and functions. If users want to learn more about the functions of the electronic load, they can directly contact customer service on the official website or make a phone call to communicate, and they can answer their questions about the electronic load in detail in a while. 2021-11-25 09:11:57

The resistor manufacturer introduces the attention to the selection of product types!

Resistors are generally directly called resistors in daily life. It is a current-limiting component. After the resistor is connected to the circuit, the resistance of the resistor is fixed, usually two pins, which can limit the current through the branch connected to it. The resistance that cannot be changed is called a fixed resistor. In order for everyone to make a better choice, the following resistor manufacturers will explain to you the considerations for the selection of product types: 2021-11-25 09:11:50

What is a wire wound resistor?

Wire wound resistors are a type of fixed resistors. Wire-wound resistors are constructed by winding resistance wires on an insulating frame. The resistance wire is generally made of nickel-chromium, manganese-copper and other alloys with a certain resistivity. The insulating frame is made of materials such as ceramics, plastics, and metal coated with an insulating layer into various shapes such as tube and flat shapes. The resistance wire can be wound on the skeleton in one layer or multiple layers as needed, or non-inductive winding method can be used. Winding resistors are mainly used in AC and DC circuits such as precision instruments, telecommunications instruments, and electronic equipment for voltage division, voltage reduction, shunting and load resistance. 2021-11-25 09:11:49

The necessity of daily inspection and maintenance of load box

At present, the generator set test system with load box as the core has been widely recognized in the market, and the demand is growing rapidly.
