Audited Supplier Digital power frequency peak voltmeter/High voltage transmission line parameter tester/Different frequency parameter tester
Product Overview:
In the traditional power frequency parameter test of transmission lines, the test power supply is provided by three-phase autotransformer and large capacity isolation transformer, and the electrical signal is transformed by CT and PT for power measurement. Finally, the electrical parameters are measured by pointer type high-precision voltmeter, ammeter and power meter, and the test results of power frequency parameter of transmission lines are calculated. The whole set of test equipment is large, heavy, need to work with the crane, which is not conducive to field measurement, and because the test power supply is the power frequency power supply, easy to mix with the coupled power frequency interference signal, bringing a large measurement error, the need to greatly improve the signal-to-noise ratio, which further improves the capacity and volume of the power supply.
The KD-110 transmission line power frequency parameter tester can accurately measure the power frequency parameters (positive sequence capacitance, positive sequence impedance, zero sequence capacitance, zero sequence impedance, mutual inductance and coupling capacitance, etc.) of various high-voltage transmission lines (overhead, cable, overhead cable mix, and multiple sets of the same pole). Meet the requirements of "110 kV and above power transmission and transformation capital construction project start acceptance Procedures", DL/T559-94 "220-500kV network relay protection device operation adjustment procedures", "GB50150-2006".
The instrument adopts integrated structure, built-in variable frequency power module, variable frequency voltage adjustable output power supply. Digital filtering technology is adopted to avoid the interference of power frequency electric field, and the difficult problem of accurate measurement under strong electric field interference is fundamentally solved.

Product features:
1, quickly and accurately complete the line's positive sequence capacitance, zero sequence capacitance, positive sequence impedance, zero sequence impedance and other parameters measurement, but also can measure the mutual inductance reactance and coupling capacitance measurement between the lines;
2, strong anti-interference ability, can be accurately measured under the condition of 1:10 ratio of different frequency signal and power frequency signal;
3, the external connection is simple, only one access to the lead line of the line under test can complete the line parameter measurement; Thoroughly solve the problems of cumbersome test wiring switching, interference, stability, accuracy and other aspects existing in the existing test means.
4, 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.
5, 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;
6, 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;
7, the measurement accuracy is high, the instrument itself provides three groups of different frequency power supply close to the power frequency (42.5Hz/57.5Hz 45Hz/55Hz 47.5Hz/52.5Hz) to choose from, easy separation of power frequency and clutter interference, effectively achieve high-precision measurement of small signals;
