A Direct Reading High-Voltage Capacitanice Bridge

In contrast with the conventional Schering bridge, the network described in this paper is direct reading for both dissipation factor and capacitance, has a fixed guard adjustment, and hence simplified operation. A unique method of phase-angle compensation employs adjustment of the effective phase angle of the standard capacitor. This compensation may be either positive or negative as required. Design is simplified since compensation for stray wiring capacitances is easily accomplished. Simplified operation and elimination of all calculations permit substantial reductions in unit testing time and operation by nontechnical personnel without sacrifice of accuracy.
