An Investigation of Parasitic Capacitance Determination Using High Frequency Injection Technique for Non-Contact Voltage Measurement System An Investigation of Parasitic Capacitance Determination Using High Frequency Injection Technique for Non-Contact Voltage Measurement System Noppawit, Longseng Kittikhun, Thongpull Noppawit, Longseng Kittikhun, Thongpull The growing demand for smart energy and smart metering concepts increase the development of advanced measurement devices and systems. However, conventional voltage measurement systems in power lines require physical contact with the conductor inside the power line. This method is still common nowadays whereas inconvenient installation and unsafe for the operators. This paper proposes a method of non-contact voltage measurement exploiting the parasitic capacitive coupling with online capacitance determination. The parasitic capacitive coupling occurred by covering metal plates around an insulated power line cable. The capacitance determination employs a high-frequency signal injection technique that transmits a reference signal to calculate the established parasitic capacitance value. The proposed method has been experimented with to determine the capacitor value generated by the capacitive coupling which then is used to calculate the actual voltage of the power line. From the experimental results, the proposed voltage measurement system can measure the actual voltage of the power line with the capability to eliminate noise errors and impact uncertainty under various conditions.
