Measurement of Ion Flow Charging Voltage Under DC Transmission Lines [Field Measurement]

By measuring the ion flow charging voltage to check the electrical environment under the DC transmission line, it is possible to obtain fundamental data.

"Measurement of ion flow charging voltage" refers to measuring the charging voltage generated by the ion flow charging phenomenon near the ground under a DC transmission line. The ion flow charging phenomenon refers to the process where molecules in the air are ionized by a high voltage applied to an electrode, and the resulting ions move to impart charge to other objects. It is possible to measure the ion flow charging voltage under a DC transmission line as a self-inspection and understand the electrical environment beneath the line. 【Examples of Achievements】 ■ Measurement Items and Conditions - Received a request to measure the ion flow charging voltage under a DC transmission line and conducted continuous measurements (at 30-second intervals) over the course of one year. - In addition to the charging voltage, meteorological data such as local temperature, humidity, wind direction, wind speed, and rainfall were also collected. ■ Submitted Data - Narrowed down the analysis targets based on selected conditions such as weather and wind speed. - Created a cumulative frequency distribution based on the measured values of the charging voltage.
