NR5900 series line parameter tester
This instrument can accurately measure the power frequency parameters (positive sequence capacitance, positive sequence impedance, zero sequence capacitance, zero sequence impedance, mutual inductance, and coupling capacitance) of various high-voltage transmission lines (overhead, cable, overhead cable mixed, and multi-circuit on the same pole). Wait).
◆Accurately measure the positive sequence capacitance, zero sequence capacitance, positive sequence impedance, zero sequence impedance and other parameters of the line;
◆ Accurate measurement of mutual inductance and coupling capacitance between lines;
◆ The test time is shortened and the workload is greatly reduced. Two hours of the traditional method can be completed within 30 minutes.
