A computer-controlled 300-kV pulse generator

A high-voltage pulse generator (HVPG) used primarily for calibrating precision high-voltage dividers has been redesigned and rebuilt for state-of-the-art operation. It has the capability to run a divider calibration in much shorter time, compare the results with historical data for the divider, and then print a calibration certificate, all under computer control. Thirteen component instruments are controlled by way of three IEEE-448 buses. A voice synthesizer is used to inform the operator of the progress of the calibration. Measurement precision is in the 0.1% range. A heat exchanger is used to control the temperature of the oil bath to allow calibration of dividers between 13 degrees C (55 degrees F) and 21 degrees C (70 degrees F). Positive or negative pulse polarity may be selected, and pulse magnitude is adjustable from less than 10 kV to greater than 300 kV.<
