Fundamental Principles of High Voltage Experimental Techniques

Abstract

High alternating voltages are required in laboratories for experiments and a.c. tests as well as for most of the circuits for the generation of high direct and impulse voltages. Test transformers generally used for this purpose have considerably lower power rating and frequently much larger transformer ratios than power transformers. The primary current is usually supplied by regulating transformers fed from the mains supply or, in special cases, by synchronous generators.
