    High voltage d-c electric power transmission has been envisioned for many years, but numerous obstacles have prevented its use to any great extent. Most of these obstacles appear to be over come in the system described in this paper; this system comprises conversion of constant-potential a-c power to constant-current d-c power, transmission of constant-current d-c power and reconversion to constan...

    Cited by:  Papers (12)
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (2370 KB)  

    Field experience and tests show that unexpectedly high transient sheath voltage occur during the switching of charging current in single-conductor cable-type bus leads and in underground single-conductor power transmission cables bonded to eliminate sheath losses. No sheath troubles from these voltages have been found. Theoretical analysis of these voltages is presented together with suggested met... View full abstract»

    The 2 principles of noise measurement, namely, the subjective and objective principles, are discussed in this paper with special reference to electrical plant. Two forms of measurement embodying the subjective principle are considered: One is the proposed primary standard method, which is essentially a laboratory method; the other is the noise audiometer, which enables the subjective principle to ...

    The correlation of the pressure and temperature effects in determining the dielectric strength of mineral insulating oils is considered in this paper. The effect which gas dissolved in the oil has on the dielectric strength of the oil is shown by experimental results of tests on the effect of temperature and pressure. Based upon these results, simple formulas for expressing the dielectric strength... View full abstract»
