The use of air condensers as high-voltage standards
Autor: B.G. Churcher, C. Dannatt
Publikováno v: Journal of the Institution of Electrical Engineers. 69:1019-1027
The paper discusses the essentials of correct screening for high-voltage air condensers in order to maintain a high degree of purity and constancy of capacitance with voltage. Tests are described showing the effect of dust and humidity on the purity

The performance of noise meters in terms of the primary standard
Autor: A.J. King, B.G. Churcher
Publikováno v: Journal of the Institution of Electrical Engineers. 81:57-81
The paper discusses the performance of noise meters, such as are used for engineering measurements, in terms of the primary standard of “Equivalent Loudness” which has recently been formulated. The unit of equivalent loudness is the British Stand

The limitation of transformer noise
Autor: B.G. Churcher, A.J. King
Publikováno v: Journal of the Institution of Electrical Engineers. 87:539-554
The paper describes a quantitative investigation into the subject of the noise emitted by transformers, and possible measures for its limitation. Permissible noise-levels for different situations are discussed and data for residential districts given

Contact effects between electrodes and dielectrics
Autor: B.G. Churcher, C. Dannatt, J.W. Dalgleish
Publikováno v: Journal of the Institution of Electrical Engineers. 67:271-290
This report covers a research on the phenomena of so-called ?contact resistance?. The research was carried out, on the suggestion of the E.R.A., by the Metropolitan-Vickers Electrical Co., Ltd., and the results show the nature and importance of conta

The measurement of noise, with special reference to engineering noise problems
Autor: H. Davies, B.G. Churcher, A.J. King
Publikováno v: Journal of the Institution of Electrical Engineers. 75:401-422
The paper deals with a detailed investigation of noise measurement for the purpose of establishing methods generally applicable to the sustained noises encountered in engineering. The work follows on that described in a previous paper. The necessity

The measurement of the ratio and phase displacement of high alternating voltages
Autor: B.G. Churcher
Publikováno v: Journal of the Institution of Electrical Engineers. 65:430-439
The paper describes null methods of measuring the ratio and phase displacement of two alternating voltages. The methods are particularly applicable to high voltages and are discussed in connection with the testing of power transformers and potential
