VT1115SFCX is an integrated AC voltage and current product specifically designed for advanced single-sided, two-sided, three-phase, and four-phase AC power measurement. VT1115SFCX can measure the voltage and current of each leg of three-phase power system accurately, and can display the active power, apparent power, reactive power, power factor, phase angle and frequency at the same time. The VT1115SFCX helps to ensure the steady operation of the power system, making it possible to quickly diagnose the abnormal operation of the system and find problems.

Application field

VT1115SFCX is applicable in industrial environments which measure AC power line voltage and current for single-sided, two-sided, three-phase, and four-phase AC power. Enterprises or laboratories who use this must be equipped with an independent three-phase AC power line and reasonable power system. It is also used in the fields of electric power measurement, measurement of electrical energy saving, field calibration of intelligent meter, remote power metering, power line communication, automatic system coupling balance, transducer dependence measuring, smart grid, etc.

Working principle

VT1115SFCX is a self-contained power monitoring unit. The VT1115SFCX consists of three parts: sensors, A/D module, display devices. First, sensors are used to measure the voltage and current of the power system. Then a A/D module is used to convert analog signals to digital signals. Finally, display devices display the digital signals received from A/D module. In this way, the VT1115SFCX can measure the voltage and current of each leg of the three-phase power system accurately.

VT1115SFCX uses calculation methods to measure various parameters such as active power, apparent power, reactive power, power factor, phase angle and frequency. In the process of measuring the amplitude and phase angle of three-phase current, a full bridge current sensor is firstly used. Then the three-phase current is converted into three-phase voltage by CRM equipment, and phase shift and amplitude measurement is performed at pre-set frequencies. The values of the measurements are then sent to an A/D module. In turn, the A/D module computes the active power, apparent power, reactive power, power factor, phase angle and frequency, which is displayed by the display unit.

Conclusion

VT1115SFCX is a self-contained type of device for measuring the AC power line voltage and current. It is suitable for single-sided, two-sided, three-phase, and four-phase AC power. Enterprises or laboratories who wish to use VT1115SFCX should have an independent three-phase AC power line and reasonable power system. It also can be used in the fields of electric-power measurement, measurement of electrical energy saving, field calibration of intelligent meter, remote power metering, power line communication, automatic system coupling balance, transducer dependence measuring, smart grid, etc. The VT1115SFCX accurately measure the voltage and current of each leg of three-phase power system, and display these data such as active power, apparent power, reactive power, power factor, phase angle and frequency. Therefore, it is an important equipment for the operations of enterprises or laboratories.
