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...
The relay that controls the original is to control the closing action by generating the minimum current for the pull-in action. Generally, in use, the given current needs to be slightly larger than th...
With the rapid development of the industry, with the development of new electric energy meters, magnetic latching relays have also ushered in rapid development. Relays have become an indispensable and...
From the perspective of structure and working principle, the magnetic latching relay is an automatic switch, and it is also a new type of relay developed in recent years. The magnetic latching relay h...
In the operation of power transformation and distribution, transformers are indispensable. It is very necessary to be familiar with and master the basic knowledge of transformers. The basic knowledge ...
A transformer is a device that transforms AC voltage, current, and impedance. When an AC current is passed through the primary coil, an AC magnetic flux is generated in the iron core (or magnetic core...
What is the difference between Hall current sensor, transformer, and shuntHall current sensor: It is a sensor that uses the Hall effect to convert a large current into a secondary tiny voltage signal....
Magnetic latching relay is a new type of relay developed in recent years, and it is also an automatic switch. Like other electromagnetic relays, it automatically turns on and off the circuit. The diff...
