The effect of applied voltage is to increase the
electric strength, hence increasing the jet stretching force, whereas the effect of spinning distance is to reduce the
electric strength, which may favor the formation of non uniform fibers.
The speed at its rim would be v [approximately equal to] 300m/sec and with an
electric strength E = 300kV/m the so called "convection current" provides magnetic field B = [10.sup.-9] T = [10.sup.-5] Gauss.
where [f.sub.v] and [F.sub.u]--distribution density of overvoltages and distribution function of insulation
electric strength for such overvoltages type; q--probability of failure of the insulation if such overvoltage occurred, or probability of a random event (V>U), when overvoltage amplitude is greater than the limit of electrical strength; min (V) and max (V)--minimum and maximum possible overvoltage values in the network.
5 is representation area field
electric strength. As you can see from this chart, was in this part field decrease electric intensity in view to distance less, as is apparent with chart.
The results of the experimental determination of the pulsed
electric strength of the soil at NTU <<KhPI>> showed [11] that this quantity is non-linear, i.e.
In this case, it is no longer the conductivity but the permittivity that has the major influence on the
electric strength uncertainty.
The integral distribution functions of long-term
electric strength are shown in Fig.
Such tree structures--clusters [7-9] representing the number of water-filled micro-cavities with connecting channels, reduce the
electric strength of the polymer insulation.
