In order to reduce the reactive power loss, the method of parallel compensation capacitor bank is usually used to improve the power factor. In practical applications, the accident rate of the capacitor compensation device is relatively high, which is determined by the characteristics of the working state of the capacitor compensation device.

1. Overview:

In order to reduce the reactive power loss, the method of parallel compensation capacitor bank is usually used to improve the power factor. In practical applications, the accident rate of the capacitor compensation device is relatively high, which is determined by the characteristics of the working state of the capacitor compensation device. Therefore, it is very important to detect the compensation capacitor regularly, find the defect of the capacitor early and avoid the expansion of the fault. In the field, the capacitors are all connected in groups in parallel, so the general capacitance meter needs to remove the lead wire before measurement, which is a heavy workload and is easy to cause wiring errors and damage to the capacitors.

The capacitance inductance tester developed by our company uses high-precision, large-opening clamp-on current transformer for current measurement, using anti-interference power output, high test accuracy, stable data, and strong anti-interference ability. It can be tested in a strong magnetic field environment without affecting the accuracy. It is a high-performance special compensation capacitor tester. The instrument can not only test single-phase capacitors, but also has a three-phase capacitor test function. It is simple and convenient to perform one-key measurement for three-phase capacitor banks with different connection methods. At the same time, the instrument can also test various reactors and resistors, and the instrument can also perform current tests separately.

Main functions and features of 2.

　　1. Power output:The power output adopts advanced PID regulation algorithm for constant current limiting voltage output, which enhances the accuracy and stability of the measurement, and the output short circuit will not damage the instrument.

2. Single-phase test function:The instrument can measure single-phase capacitors, reactors and resistors. At the same time, automatic test can be selected for single-phase measurement, and the instrument can automatically judge the type of sample.

3. Three-phase capacitor test function:The instrument has three-phase power output and interface, which can connect three-phase Y-type connection capacitor, three-phase Yn-type connection capacitor, three-phase △-type connection capacitor and three-phase III-type connection capacitor once to complete three-phase capacitance test and separately test and calculate the phase capacitance. It is simple and convenient, and greatly improves the work efficiency of field users.

4. Capacitance measurement:Accurately set the rated frequency and rated voltage of the capacitor test sample, and the instrument can automatically calculate the compensation capacity of the capacitor, reducing the calculation amount of on-site personnel.

5. Test reactance measurement:The instrument can automatically calculate the capacitive reactance, inductive reactance and impedance of the sample according to the measurement results, which is convenient for further data analysis on site.

6. Current test function:The instrument clamp current transformer can be used for current detection alone, which can detect the fundamental effective value of the current signal, the total harmonic distortion, the signal frequency and the 3. 5. 7. the ninth harmonic content rate, so as to carry out a simple power quality analysis of the current signal.

　　7. Instrument:Using large-screen LCD display, using Chinese menu, Chinese prompt, simple operation.

　　8. No power-down clock and date display:Data storage methods are divided into local storage and USB storage, in which local storage can store 200 pieces of test data, and local storage can be transferred to USB. The USB storage data format is Word format, which can be edited and printed directly on the computer.

9. Thermal printer printing function, fast and silent.

10. The human-computer interaction interface is more friendly:The status bar at the top of the screen displays the USB insertion status, test status, storage status, etc. in real time, and displays the corresponding unconnected prompt message when operating the unconnected device.

11. Small size, light weight, easy to carry and use.
