Capacitance And Inductance Tester

CL-II Capacitance and Inductance Tester

Performance characteristics:

2.1 Lithium battery power supply mode:

The instrument has a built-in large-capacity lithium battery. It can be measured without AC power during field testing, and the measurement time is long, and it is simple and convenient to use.

2.2 Different frequency power output:

    The instrument uses the output of the different frequency power supply for testing, which greatly improves the anti-interference ability of the site, and can be tested in a high-strength magnetic field without affecting the accuracy; the different frequency power supply adopts advanced inverter technology with soft start and soft stop functions. It greatly reduces the impact on the test product and better protects the test product. At the same time, the power output adopts the advanced PID adjustment algorithm for constant current and voltage limiting output, which strengthens the accuracy and stability of the measurement, and the output short circuit will not damage the instrument.

2.3 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 determine the type of test product.

2.4 Three-phase capacitance test function:

The instrument has a three-phase power output and interface. It can connect three-phase Y-type junction capacitors, three-phase Yn-type junction capacitors, three-phase delta-type junction capacitors, and three-phase III-type junction capacitors to complete three-phase capacitance testing. It is simple and convenient to test and calculate the split-phase capacitors separately, which greatly improves the work efficiency of field users.

2.5 Capacitance measurement:

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

2.6 Test product reactance measurement:

The instrument can automatically calculate the capacitive reactance, inductive reactance, and impedance of the test product according to the measurement result, which is convenient for further analysis of the data on site.

2.7 Current test function:

The clamp-on current transformer can be used for current detection alone. It can detect the effective value of the fundamental wave, total harmonic distortion, signal frequency and the third, fifth, seventh, and ninth harmonic content rate of the current signal, so as to correct the current signal Perform a simple power quality analysis.
