MS1015E is a general purpose current-voltage converter based on the operation principle of inductive coupling. It is suitable for measuring parameters such as current, voltage, power, frequency, phase shift, resistance and other important electrical parameters in the applications ranging from electric drive frequency conversion equipment to power distribution systems and electrical instrumentation systems. This article will explore the application fields and working principles of MS1015E.

The application fields of MS1015E are mainly in the areas of electrical engineering, automation, machinery, new energy, military industry and other industries. In electric drive frequency conversion equipment, the MS1015E has been widely used for monitoring the operation of the inverter, including the current, voltage, power and phase shift measurement and control, to ensure smooth running and reliability of the systems. In the distribution system, the MS1015E is applied in the measurement and control of the bus bar and switchgear current, helping to detect the fault information and provide an effective preventive measure. Lastly, in the test instrumentation systems, MS1015E serves as a shunt calibration instrument for the calibration of high-precision meters and measurement of low-level current signals.

The MS1015E adopts a voltage transformer plus inductive coupling principle to achieve the conversion between current and voltage signal. This voltage transformer combined inductive coupling includes a conductor inside the core of a magnetic red core, a copper wire driven by the primary side circuit, and one or two secondary coils. When a current flows through the primary coil, the magnetic field generated by the primary circuit will induce a voltage in the secondary coil. Then this converted voltage signal is transmitted to the signal output terminal.

In addition to the simple inductive coupling, MS1015E also uses high-precision shear shaft differential transformer shunt technology as a reference for current, voltage and other parameters. With this technology, the shunt differential transmission system will reduce the error of the signal in the induction process and maintain the accuracy of measurement. In this way, the accuracy of the acquired electrical parameters can be improved after being processed by the signal analysis circuit, and can be output as standard voltage signals.

In short, MS1015E is an advanced device for monitoring the parameters of electric drive frequency conversion equipment, power distribution systems, and electrical instrumentation systems. It renders high accuracy measurement using voltage transformer and inductive coupling and shunt technologies combined. With it, the performance, safety and reliability of the electric power equipment can be improved.
