Direct Capacity Measurement

Not Accessible

Abstract

Synopsis

Direct capacity, direct admittance and direct impedance are defined as the branch constants of the particular direct network which is equivalent to any given electrical system. Typical methods of measuring these direct constants are described with especial reference to direct admittance; the substitution alternating current bridge method, due to Colpitts, is the preferred method, and for this suitable variable capacities and conductances are described, and shielding is recommended. Proposed methods are also described involving the introduction of electron tubes into the measuring set, which will reduce the measurement to a single setting or deflection. This gives an alternating current method which is comparable with Maxwell’s single null-setting cyclical charge and discharge method. Special attention is drawn to Maxwell’s remarkable method which is entirely ignored by at least most of the modern textbooks and handbooks.
