Product Introduction
KG-110B line parameter tester is a high-precision test instrument for testing various high-voltage transmission line parameters in power stations, substations and other on-site or laboratory. The instrument is an integrated structure, built-in frequency conversion power module, variable frequency voltage control output power supply. The frequency can be changed to 45Hz or 55Hz, and digital filtering technology is adopted to avoid the interference of power frequency electric field on the test, and fundamentally solve the problem of accurate measurement under the strong electric field interference. At the same time, it is suitable for the test of generator power supply after all power failure.
KG-110B line parameter tester accurately measures the positive sequence capacitance, zero sequence capacitance, positive sequence impedance, zero sequence impedance, mutual inductance and coupling capacitance, and interphase capacitance of various high-voltage transmission lines.
In the traditional transmission line power frequency parameter test, it is necessary to use three-phase autovoltage regulator and large capacity isolation transformer to provide test power supply, through the power measurement of CT and PT for electrical signal conversion, with pointer type high-precision 3 voltmeter, 3 ammeter, 3 power meter, multiple readings to measure each electrical parameter, calculate the transmission line power frequency parameter test results. The whole set of test equipment is large in volume and weight, and it needs to work with the crane, which is not conducive to the field measurement. The KG-110B line parameter tester can replace the workload of the traditional transmission line frequency parameter test (20 hours) in a single machine (20 minutes), with high efficiency and accuracy!
