Kyiv: Naukova Dumka, 1985. - 264 s. The monograph shows the influence of neutral modes on the most important performance indicators of electrical distribution networks of various voltages. Loads and currents in the network at a single-phase closure to the ground. Uncompensated network with isolated neutral . Net with neutral grounding through high ammo active resistance. Compensated network . Nets with effective neutral grounding. Ferro-resonance processes in ES when the phase is closed to the ground. Ferroresonance processes in the network that occur when it is in good condition. Methods for performing grounding of neutral uncompensated networks and automatic closure to the ground of the damaged phase. Automatic adjustment of circuit current compensation to the ground. Neutral voltage limitation in compensated network. Suitable modes of neutral electrical networks.
