High-voltage dc measurements usually involve a high-resistancevoltage divider which usually forms a high resistance to the circuit being measured and thus draws infinitesimal current.
High-voltage DC measurements usually involve a high-resistancevoltage divider, which usually forms a high resistance to the circuit being measured and thus draws infinitesimal current.
The technical index and calibration level of the DC resistancevoltage divider are analyzed, the uniform calibration method is proposed, the uncertainty is analyzed and the checking method is given.
