Description
Overview
In the traditional power frequency parameter test of transmission lines, the test power supply is provided by a 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 a pointer-type high-precision voltmeter, ammeter, and power meter, and the test results of the power frequency parameter of transmission lines are calculated. The whole set of test equipment is large, and heavy, and needs 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.
