The LPSR 25-NP is a current transducer capable of accurately measuring DC currents in a range from basic AC/DC current levels and those found in heavy industrial applications. This transducer is designed with a wide power range, up to 2500 A and a high accuracy of 0.15 %. The LPSR 25-NP transducer is constructed with a heavy duty shell and is rated for both overload protection and vibration resistance. This current transducer is suitable for both indoor and outdoor applications.

The basic working principle of the LPSR 25-NP current transducer is based on Hall Effect. Hall Effect is a phenomenon in which a voltage is induced in a conductor when a current passes through the conductor in the presence of a magnetic field. The magnetic field is generated by the coil around the conductor when a current passes through it, which in turn induces a voltage. This voltage is then proportional to the strength of the applied magnetic field and is measured by the secondary windings of the LPSR 25-NP transducer.

In order to obtain an accurate measurement of current, it is important to ensure that the transducer is properly configured and calibrated. The calibration process includes connecting the transducer to a known current measurement device, connecting the primary winding to the power supply, setting the zero point of the secondary winding and then adjusting the gain coefficient. Once this calibration process is complete, the LPSR 25-NP can then be used to measure DC current levels accurately.

The LPSR 25-NP transducer is also suitable for applications requiring AC current measurements. This type of applications would be jobs involving motors, motor controllers and even power distribution systems. Here again, the calibration process needs to be carefully done and regular maintenance is needed to ensure the accuracy of measurements.

In addition to its ability to accurately measure DC and AC currents, the LPSR 25-NP also features built-in Self Test and Remote Tapping capabilities. Self Test allows the transducer to be checked for proper operation by measuring the voltage output of the transducer and comparing it to a pre-determined reference level. Additionally, the self test feature checks for proper insulation of the windings and can detect problems like short circuits or high contact resistance. Remote Tapping is the process of connecting a device (such as a display unit) to the secondary winding of the transducer for display of the current readings. This allows for better control of the power system by precisely monitoring the current levels at all times.

The LPSR 25-NP current transducer is one of the most versatile and reliable current transducers on the market today. With its wide power range, high accuracy and built-in features, this current transducer is suitable for a wide range of applications including motors, power distribution systems, industrial control systems and much more. Its rugged construction and vibration resistant design make it suitable for both indoor and outdoor applications. Furthermore, its calibration process and self test/remote tapping features provide a reliable and accurate means to measure and monitor current levels in any application.
