A HIGH-BANDWIDTH, HIGH-VOLTAGE DIVIDER FOR NEUTRAL INJECTORS

The paper describes the design, construction, calibration and testing of a voltage divider for which the influence of space potential variation as well as the pick-up of RF- and inductive interference is grossly reduced by its special design. It features voltage capability up to 160 kV, measuring accuracy approaching 10 −3 over a bandwidth from d.c. to 100 kHz with negligible phase error, and useful measuring capability to beyond 10 MHz.
