Automatic Three-Phase Capacitance and Inductance Tester
I. Overview
In response to the actual conditions on site, our company has developed a new testing method for measurement, which is the Three-Phase Capacitance and Inductance Tester. This instrument can measure the single-phase capacitance of a group of parallel capacitors or three-phase capacitors of various connection types without disconnecting the wires. It can also measure the inductance of various reactors. Additionally, it can measure current under power frequency conditions. The instrument features convenient wiring and simple operation, reducing the workload of maintenance personnel and greatly improving on-site testing efficiency, thus providing safety assurance for the normal operation of the power grid.
II. Functional Features
l This instrument can measure the single-phase capacitance of a group of parallel capacitors without disconnecting wires, and simultaneously measure three-phase capacitors of various connection types. It can also measure the inductance of various reactors and can be used as a power frequency current tester. It serves three purposes in one, meeting various on-site needs.
l During measurement, the instrument displays the measured capacitance or inductance value, as well as voltage, current, power, frequency, impedance, phase angle, and other data for better analysis of the test object's condition.
l The instrument uses a 240×128 large-screen LCD with backlight, ensuring clear visibility both day and night. It features Chinese menu prompts and is easy to operate.
l The instrument has a built-in large-capacity non-volatile memory that can store 50 sets of measurement data.
l The instrument has a built-in high-precision real-time clock function for date and time calibration.
l The instrument comes with a built-in high-speed micro thermal printer that can print measurement and historical data.
l The instrument has overcurrent protection for the test power supply: a short circuit in the power output will not damage the instrument.
