If you have a Prepayment meter, you need to get a shunt installed to prevent unauthorized access to your meter's data. These shunts are not as difficult to install as they might seem, but they are sti...
In a power meter, energy consumption is measured by measuring the current flowing into a load. The power of a device depends on both the voltage applied to it and the current flowing into it. To meas...
The pressure relay can sense the pressure of the system and send a switch signal. When the pressure is reached, the normally open contact closes and the normally closed contact opens. We can use it pr...
A shunt is built on the principle of detecting a voltage across a resistor when a DC current is passed through it. The shunt is a direct detection method, and the upper limit of the measured current i...
There are many methods of the current measurement. Each method is suitable for different occasions, and each method has its own characteristics. This article introduces several common current measurem...
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...
