Phase Wire Break Signaling for 6 – 10 kV Overhead Line
To detect phase wire breaks in a 6 – 10 kV overhead line, the negative-sequence voltage on the low-tension side of the 6 – 10/0.4 kV power transformer can be used. The results of studying the effect of a phase wire break in an overhead line, phase displacement groups, and phase unbalance of demand loads in a 380 V network on the negative-sequence voltage are presented. A device for signaling phase wire breaks in a 6 – 10 kV overhead line is described. The device is based on a microprocessor electricity meter installed on the low-tension side of a 6 – 10/0.4 kV power transformer.
