CR4810-250 is a current transformer and voltage transducer used in various applications such as power system monitoring, transmission and distribution, high-voltage electrical systems, and instrumentation and control systems. It is used to accurately measure the voltage and current in an electrical power system. The voltage and current measurements are converted into normalized industrial signal outputs (voltages or currents) which can then be processed and monitored.

The CR4810-250 is a two-piece magnetic device that comprises a current transformer and a voltage transducer. The current transformer is connected between the line side and the branch side of the power system. It is used to monitor the current flow in the system and detect any overloads, surges, or overvoltages in the system. The voltage transducer is connected between the line side and branch side of the system. It is used to monitor the voltage of the system and detect any high or low voltage levels.

The CR4810-250 has several features that provide superior accuracy and flexibility. The current transformer and voltage transducer both feature a precision ratio up to ±0.1%. The current transformer has a maximum rated current of 250A, and the voltage transducer has a maximum rated voltage of 400Vrms. The output can be scaled according to the user’s requirements, with a maximum range of 1A/1V. The CR4810-250 also offers galvanic isolation between input and output signals, and between the power and signal side. The device is designed to be operated in harsh environments, with a wide temperature range of -40°C to +100°C.

The working principle of the CR4810-250 is based on the Faraday’s law of induction. When an alternating current passes through a coil, a voltage is induced in the coil. This voltage is proportional to the rate of change of the current flow and is known as the induced voltage. The current transformer uses this principle to measure the current in the system. The voltage transducer uses the same principle to measure the voltage in the system.

The CR4810-250 is an ideal solution for monitoring and controlling power systems, as it provides accurate and reliable data on the voltage and current in the system. Its features make it suitable for use in a wide range of applications, including industrial automation, energy management, safety, and control. It has a long service life and is designed to withstand adverse environmental conditions.
