摘要
FIELD: electricity.;SUBSTANCE: according to the method if at disappearance of current in a zero wire the phase voltage system became asymmetrical when phase voltages differ by an absolute value and change both towards decrease, approaching to a zero value, and towards increase, approaching to a linear value, depending on connection or disconnection of single-phase consumers, then the conclusion is made on the zero wire break and break of connection of the substation earthing loop with the transformer neutral point.;EFFECT: expansion of the method functionality by obtaining the information on break of the zero wire and break of connection of the substation earthing contour with the transformer neutral point.;2 dwg
