A current transformer (CT) is an electrical instrument that transforms electric current from one form to another. The basic parts of a CT are the magnetic core and secondary winding. The primary linin...
A single-phase meter shunt is used to measure the line and neutral current of an electrical circuit. The design of this device allows it to function with both configurations, while still maintaining i...
One of the most common uses for Energy Meter Shunts is to test the accuracy of a meter's output voltage. Shunts are a good option for this purpose because they produce very low output voltages, while ...
A prepayment meter is a meter with a prepayment feature. A shunt is a small mechanical device that is connected to a meter's reading system. It is used to read and write the amount of money that a cu...
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...
