The principle of the shunt The shunt is made according to the principle of generating a voltage across the resistor when the DC current passes through the resistor. The shunt is actually a resistor wi...
The power transformer is the most important equipment in the power system. It uses the principle of electromagnetic induction to convert alternating current energy of one voltage level into alternatin...
Transformer noise is the sum of mechanical noise and air noise caused by irregular, intermittent, continuous, or random noise generated by the transformer body and cooling system during the design, se...
(1). First understand the necessary conditions ① The power supply voltage of the control circuit, the maximum current that can be provided; ②The voltage and current in the controlled circuit; ③ How ma...
Shunt advantage: To measure a large DC current, such as tens of amperes, or even larger, hundreds of amperes, what should I do if there is no ammeter with such a large range for current measurement? T...
Shunts are available in metal film and full metal versions. Advantages and disadvantages of metal thin film resistors: Pros: Significantly cheaper Cons: They have lower temperature coefficient perfor...
Using a shunt to measure current is a simpler and more cost-effective alternative to using a sensor for current measurement. However, shunts are precision measurement devices and many things need to b...
1. The role of the shunt It is used to expand the measuring current range of the instrument, and it is used for current limiting and current sharing sampling detection in the loop of the instrument, ...
1. How to use the shunt Select the rated voltage drop specification of the shunt according to the mV number marked on the dial of the ammeter (or current-voltage dual-purpose meter) used (75mV or 45mV...
The winding and iron core of the c-type transformer are the primary components for transmitting and converting electromagnetic energy. Keeping them workable is a concern. Statistics show that the iron...
Industrial control relays are common relays in the industry. Generally speaking, a relay is an automatic control electrical appliance that acts according to a specific input signal. There are many typ...
There are many types of relays, so how do we classify them? Here we will classify them according to the working principle, product use, external dimensions, protection features, contact loads, etc. of...
