Profile:
Quickly and accurately measure the positive sequence capacitance, zero sequence capacitance, positive sequence impedance, zero sequence impedance and other parameters of the line, and also measure the mutual inductance reactance and coupling capacitance between the lines.
Features:
1.Strong anti-interference ability, can be accurately measured under the condition that the ratio of different frequency signal and power frequency signal is 1:10;
2. the external connection is simple, only one access to the lead line of the line under test can complete the measurement of all line parameters; Thoroughly solve the problems of cumbersome test wiring switching, interference, stability, accuracy and other aspects existing in the existing test means.
3.the instrument with high-speed single-chip microcomputer as the core, to achieve the integration of test power supply, instrument, calculation model, a truck of equipment concentrated into one instrument.
4. the instrument adopts 320*240 large screen dot matrix LCD display, rotary mouse operation imported from the United States, embedded Chinese micro printer printing results, the operation is very easy;
5. the instrument test process is fast, the instrument automatically completes the test mode control, pressure control and data measurement calculation, and prints the measurement results, the measurement of a sequence parameter is completed in one minute, the test time is shortened, the workload is greatly reduced, 20 minutes can complete the traditional method of two hours of work;
