Dc Resistance

Aim at the electric power transformer with inductance is large, resistance is small, the inherent characteristics of the large time constant, a fast measurement scheme of power transformer winding DC resistance is proposed. The scheme adopts the increase the measurement circuit loop resistance mutation method, in which the circuit transition process from a time constant is forced to another time constant, to realize the rapid measurement of winding DC resistance in power transformer. Simulation results show the effectiveness of the scheme.

Decay Period

Emission having a large time constant has been measured recently in the decay period of plasmas produced in nitrogen and helium-nitrogen mixtures. Whereas the fast decaying emission during the early afterglow originates from the plasma volume, it was suspected that emission responsible for the large time constant (10 to 15 ms) was not due to emission processes involving nitrogen. The present studies relate to detailed measurements of this phenomenon in a decaying helium plasma produced in a Kovarglass built discharge tube. It will be shown that this slow decaying emission is due to phosphorescence of the walls of the glass tube.
