The present invention provides an electric field measurement system based on FPGA control and an application method thereof, belongs to the technical field of electrical devices, and especially relates to an electric field measurement system. Aiming at current defects, the present invention provides an electric field measurement system and an application method thereof with large measurement and application ranges of a power frequency electric field, high measurement accuracy, good safety and stable operation and suitable for a high humidity and a high temperature. In the method, an FPGA controller receives signals to switch on an electric field sensor and a temperature and humidity sensor, the temperature and humidity sensor returns temperature and humidity information to the FPGA controller, the FPGA controller processes received signals, performs flash latch of the corrected data and transmits the data to the upper computer for display, the upper computer sends the data to a handheld terminal, and when the data exceeds a set value, an alarm module starts. The electric field measurement system based on the FPGA control and the application method thereof are mainly applied to electric field measurement of a suspension field intensity indicator.
Description
technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to an electric field measurement system and a using method thereof. Background technique [0002] At present, environmental protection mostly uses suspension field strength meters for the measurement of power frequency electric fields in AC power transmission and transformation projects. Frequency induced current and induced charge, the loop formed by the capacitor and the sampling resistor between the two parts, the voltage on the resistor is measured to obtain the power frequency induced current, and the corresponding relationship between the current and the field strength is obtained through calibration, and the volume of the field strength meter Large, most field strength meters use wood or epoxy brackets. The capacitance and brackets formed by the probe itself are in direct contact with the air. When the humidity is high, the measurement results will be...
