F39-EJ1385-D Application Field and Working PrincipleAccessories are an essential part of any technical equipment or device. The F39-EJ1385-D is a type of accessory, specifically an AC current transformer, and it is used in various industries and applications. This article will discuss the application field of the F39-EJ1385-D and its working principle.The F39-EJ1385-D, also known as a current transformer, is used in the electrical industry to measure current flow in circuits. The device consists of a primary and secondary transformer coil. The primary coil is connected in series with the electrical circuit, while the secondary coil is connected in parallel. The current in the primary coil is measured and converted to a lower level of current in the secondary coil, which is easier to measure without placing any additional load on the circuit. This enables the measurement of current and power parameters in the electrical circuit without having to disconnect the circuit for direct measurement.The F39-EJ1385-D can be used in a variety of fields and applications. It is suitable for use in hazardous areas, such as chemical and petrochemical plants, and in areas with explosive atmospheres, such as oil and gas installations. It can also be used in other installations where direct current measurement is either not possible or difficult, such as in remote areas where access to the circuit is restricted. It is also used in power plants, distribution systems, and electric motors to measure current and power parameters.The F39-EJ1385-D is designed with two circuits: a primary circuit and a secondary circuit. The primary circuit consists of a primary winding, which is connected in series to the electrical circuit. This creates a magnetic field around the winding, which is proportional to the current flowing through the circuit. The secondary circuit is connected in parallel to the primary circuit. This circuit consists of a secondary winding, which is designed to detect the magnetic field created by the primary winding. The current in the secondary winding is proportional to the current in the primary winding, but at a lower level. This enables an accurate measurement of current without placing additional load in the primary circuit.In addition to measuring current, the F39-EJ1385-D can also be used to protect the circuit from overloads. It is able to detect the overload condition in the primary circuit and disconnect the secondary winding from the primary circuit before the circuit is damaged. This helps to reduce the risk of damage to the circuit and increase its life span.The F39-EJ1385-D is an important accessory for the electrical industry, offering both measurement and protection functionality. It is designed to be used in hazardous areas, remote locations, and other difficult-to-reach places, offering an accurate and reliable solution for measuring and protecting electrical circuits.
