Problems solved by technology
The existing corona current measurement schemes all have shortcomings. The acquisition equipment directly used on the high-voltage side is bulky, cumbersome to operate, and poor in portability, and the current measurement method using series resistance will change the circuit structure, resulting in high-frequency In the case of large errors in the measurement results
The equivalence of the measurement schemes on the low-voltage side has not been rigorously proven
The above three reasons make it difficult to accurately measure the corona current

Description
technical field [0001] The invention belongs to the technical field of high-voltage gas discharge measurement, and in particular relates to a high-potential corona current collection device. Background technique [0002] High-voltage power transmission has the characteristics of large capacity, low loss and low cost, and is suitable for long-distance and large-capacity power transmission. my country's regional energy distribution and power demand are extremely unbalanced, and high-voltage power transmission has become the main means to solve this contradiction. With the continuous and rapid growth of my country's economy, the demand for electric energy has increased year by year, which puts forward higher requirements for the transmission capacity of the power grid. The voltage level has also gradually increased, from the initial high voltage to ultra-high voltage to today's ultra-high voltage. Under normal operating conditions, high-voltage transmission lines are usually ...
