Chapter 3 Measurement of high voltages
Measurement of high voltages – d.c., a.c. or impulse voltages – involves unusual problems that may not be familiar to specialists in the common electrical measurement techniques. These problems increase with the magnitude of the voltage, but are still easy to solve for voltages of some 10 kV only, and become difficult if hundreds of kilovolts or even megavolts have to be measured. The difficulties are mainly related to the large structures necessary to control the electrical fields, to avoid flashover and sometimes to control the heat dissipation within the circuits.
This chapter is devoted to the measurement of voltages applied for the testing of h.v. equipment or in research. Voltage-measuring methods ...
