One of the factors that causes the proper functioning of protection systems is the correct design of the earthing system, including protective earthing, operational earthing, lightning arrester earthing system, etc., according to the relevant standards and the implementation of the equipotentialization system. After going through this stage, in line with proper implementation and monitoring and maintenance, always measure the resistance of the earth systems and check the connection of the equipotential system of the site, especially when it is not possible to separate the earth or the possibility of knocking the auxiliary electrodes according to If the conditions of the project do not exist, it is one of the concerns of the users. \r\n\r\nRetonac Shaya company, as the exclusive representative of the Polish Sonel company, offers a variety of art testers with different capabilities in accordance with the latest measurement methods. \r \nAlso, this company provides technical services such as training in various measurement methods in accordance with today's standards.

300 Amp 1200V IGBT module SKM300GB12T4 or IGBT is a power semiconductor which is actually an electronic switch used for fast switching. IGBT has advantages over MOSFET and BJT. Semimicron EGBTs have very low voltage drop and better current density in the on state.

Limit switches are used to control devices as part of a control system, as a safety lock, or to count objects that pass a point. A limit switch is an electromechanical device that consists of a mechanical actuator connected to a The category consists of contacts. When an object reaches a contact through an operator, the device causes the contacts to be disconnected and connected in order to create or disconnect the electric current.\r\n\r\nLimit switches have different applications and are used in different environments due to their strength, ease of installation and reliable performance. Limit switches are able to identify different situations such as presence or absence, rejection, positioning and identifying the end of an object\'s path. Limit switches are usually used to control the movement of machines. For example, we can refer to cutting machines, conveyor belts, automatic lathes, elevators. In general, limit switches can be used in most machines that require dimensional movement control.\r\n\r\n**[Click here to buy the product](https://www.automation24.ir/)**\r\n\r\nLimit switches were initially used to identify the end and limit of a path and to move an object, and that is why they are called limit switches.\r\n\r\nStandard limit switches are industrial control parts that have different types of operators, including push, roller, and needle types.\r\n\r\nRarely, a final actuating device such as a lamp or an electric valve is directly controlled by the contacts of an industrial limit switch. But mainly a limit switch is used with a control relay, a contactor or as an input in a PLC.\r\n\r\nWith the advancement of technology and the construction of electronic sensors, now limit switches have replaced proximity sensors in most cases.
