Abstract
A high voltage measuring system with very high input impedance. The system measures a high voltage source under test by developing a control signal which is proportional to the differential voltage between the high voltage source being tested and an adjustable high voltage reference. This control signal is fed back into a controller which adjusts the reference source so as to match the reference source with the source under test. When the controller detects that matching has occurred, it measures the reference source. By measuring the reference source, as opposed to measuring the source under test directly, the system avoids loading down the source under test.
