Solid-State Op Amp Measures Kilovolts with 0.05% Accuracy

Current drawn by an electrostatic voltmeter in high-voltage tests lowers the measured voltage and consequently limits the accuracy of the measurement. The 2% accuracy of a conventional electrostatic voltmeter causes a significant 200-volt error in a 10-kilovolt measurement. Read full article
