E39-L109 Datasheet/PDFE39-L109 Application Field and Working Principle
The E39-L109 is an accessory designed for electrical relaying, measurement and control applications. It is a 7‑mounting space, 72-terminal voltage transformer used for long-distance electrical power transmission relaying measurements. It monitors the voltage levels of electrical equipment such as power stations, substations, transmission and distribution lines. Its working principle is based on two sets of terminals connected to the transformer, where each set is in the opposite direction with respect to the other, so that the voltage output is the same as the input voltage so as to detect the changes in the frequency.
The primary function of the E39-L109 is to provide accurately measured and maintained voltages for relaying and measurement purposes. In addition, the device has been used in the field of process control to secure reliable and accurate control and monitoring of equipment, machinery, and operations. Moreover, it is the most appropriate tool for slow current injection testing, which is a process used in the electrical industry to determine the performance of the relays in the protection system.
The precise accuracy of the E39-L109 is another major advantage as it allows electricians to accurately measure and maintain the current. This is important because electrical relaying systems need consistent and precise measurements in order to work properly. This also ensures the proper operation of transmis- sion and distribution lines, which in turn ensures the electricity is supplied in a safe manner.
The E39-L109 also features a high safety level, which is important when working with electricity. It is equipped with a fuse to protect the device from any overvoltages or overloads. It also has an integral current transformer which is essential for sensing and providing accurate signals for the control system.
The E39-L109 has been widely used in many applications such as the monitoring of transmission and distribu- tion lines, process control, instrument calibration, and phase shift measurements. It is the ideal choice for any situation that requires highly accurate and consistent voltage measurements for electrical relaying and control applications.
In summary, the E39-L109 is an indispensable accessory for any electrical relaying, measurement, and control application. It provides precise and consistent voltage measurements that are essential for consistent and safe electrical supply. Moreover, its high safety level ensures that electricians can work without any fear of electric shocks.
