1. The principle of current transformer selection and inspection 1) The rated voltage of the current transformer is not less than the rated voltage of the line at the installation point; 2) Calculate the current IC according to the primary load to select the current transformer change; 3) Select the... read more
What is the working principle and function of the relay? The use of the relay in our home is still very important. It can provide the most basic living security for the home life, but we must pay attention to the use of the relay to avoid unnecessary trouble. First, What is the function and principl... read more
The role and working characteristics of the relay. The relay is an electronic control device. It has a control system (also called an input loop) and a controlled system (also called an output loop). It is usually used in automatic control circuits. A kind of "automatic switch" that uses a small cur... read more
1) Electromagnetic relay: an electrical relay that uses the suction force generated between the electromagnet core and the armature by the current in the input circuit. 2) Solid state relay: refers to a relay whose input and output are isolated with electronic components performing their functions w... read more
The car relay is broken. The relay is an important part of the car. If the starter relay is broken, the car will not start. If the ignition switch relay is broken, the car will not start, and if the power window relay is broken, the power window of the car will not be able to rise and fall. There ar... read more
