Variable Frequency Anti-Interference Large Ground Grid Tester - Yangzhou Darui
Darui Electric recommends to you
Variable Frequency Anti-Interference Large Ground GridTesteradopts a new type of different frequency AC power supply, and adopts measures such as microprocessor control and anti-interference signal processing, which effectively solves the anti-interference problem during the test process, simplifies the test operation process, how much does the automatic anti-interference ground grid resistance tester cost? improves the accuracy and precision of the test results, and greatly reduces the labor intensity and test cost of the test personnel. It is suitable for testing grounding resistance in various places such as substation ground grids of various voltage levels (4Ω), power plants, microwave stations (10Ω), lightning rods (10Ω), etc.
In one measurement process, different frequency multiple power supplies are used for measurement. The computer controls the output frequency of the power supply and through computer data acquisition and data processing, eliminates the interference sound between the measurement leads. It also uses hardware filtering technology and software filtering technology to reduce the error caused by power frequency interference to the measurement results, further improving the signal-to-noise ratio, how much does the automatic anti-interference ground grid resistance tester cost? making the instrument measurement results more stable and reliable.
