“…For this reason, a voltage divider with an attenuator is used in the HV measuring system. (11,(29)(30)(31) In addition, the factors of the measuring system are not varied by more than ±1% from the specified conditions and space clearance. The test circuit of the unit step response is depicted in Fig.…”

This paper presents applications of high-voltage (HV) resistors based on saline solution for HV impulse generation and measurement. The electrical resistivity and relative permittivity of saline solution in the frequency range from 100 Hz to 100 MHz were investigated. The electrical resistivity and relative permittivity were calculated from experimental measurements of the resistance and capacitance of saline solution in a test cell. From the characteristics and the experimental results, the technical data of saline solution with various concentrations of substances were utilized in the design of HV resistors for HV impulse generation and measurement, as a current-limiting resistor and an HV resistor used in an HV part of a voltage divider. Moreover, the developed HV resistors were tested to confirm their effectiveness in HV generation and measurement. From the experimental results, it was found that the developed HV resistors have promising characteristics for practical HV impulse generation and measurement. According to the results of this study, an HV resistor based on saline solution has strong potential for application in HV impulse generation and measurement compared with a conventional voltage divider.

“…(An example of a field shaper that accomplishes this is included in Ref. 1.) The choice of field shaper was also constrained by the access available in the Mercury generator (6 MV, 360 kA, 50 ns) [4] where the extended VVM was to be tested.…”

A standard voltmeter designed for measuring up to ± 2 MV in vacuum was modified to operate at -4 to -6 MV, appropriate levels for measuring the convolute voltage during z-pinch experiments on Z. Field shaping structures are used to eliminate electron emission from the voltmeter grading rings. The voltmeter operated as expected during tests at -4 MV on the Mercury generator, indicating this voltmeter could work for the lower voltage range expected on Z. At -6 MV on Mercury, the voltmeter did not operate correctly, probably because of electron emission. Particle-in-cell modeling is consistent with the observed voltmeter response. An improved field shaper could extend the voltmeter operation to -6 MV.

A vacuum-voltmeter (VVM) was fielded on the Saturn pulsed power generator during a series of argon gas-puff Z-pinch shots. Time-resolved voltage and separately measured load current are used to determine several dynamic properties as the load implodes, namely, the inductance, L(t), net energy coupled to the load, E(coupled)(t), and the load radius, r(t). The VVM is a two-stage voltage divider, designed to operate at voltages up to 2 MV. The VVM is presently being modified to operate at voltages up to 6 MV for eventual use on the Z generator.
