It is difficult to accurately identify the fault phase and cause of wildfires due to a tree-line fault of three-phase voltage imbalance in a distribution network. Thus a phase selection method based on the combination of voltage signal mutation value and change trend is proposed. Based on the phase selection theory of a single-phase grounding fault in a traditional three-phase voltage balanced distribution network, a 10 kV single-phase tree-line fault test platform is built. First, a single-phase tree-line fault test of various trees and different residual currents is carried out under three conditions of neutral point ungrounded, under compensation and over compensation of arc suppression coil grounding. Then, from the variation characteristics of zero sequence voltage and phase voltage amplitude during a tree-line fault, the fault time and fault phase identification code are defined, and the criterion that the lag phase is the fault phase is established when the amplitude of the effective value of a phase voltage increases the most. By comparing and judging the change of the average effective value of each phase voltage within 0.1 s before and after the fault time, the corresponding identification code is generated for matching to achieve accurate and rapid identification of the fault phase. Finally, it is verified by experiment that this method can effectively solve the problem of fault phase identification of a single-phase tree-line fault and is not affected by voltage imbalance. This has good engineering application value. © 2024 Power System Protection and Control Press. All rights reserved.

Fungal and mycotoxin contamination has been found in fordstuffs from Cixian County, an area with a high incidence of esophageal carcinoma (Eca). To set a scientific foundation for the prevention of Eca at the etiological level, fungal and mycotoxin contaminations of local foodstuffs in Cixian County were analyzed using classical fungal culture methods and HPLC. From 1990 to 1994, 220 corn/wheat samples and 34 corn samples were studied. As a control, 26 corn samples collected from a relatively low incidence area of Eca in Zanhuang County were analyzed for mycotoxins in 1990. The results showed that fungal contamination in corn and wheat was severe and that several of the predominant contaminating fungi such as Furasium moniliforme, etc. were carcinogenic. HPLC results showed that the detection rate and mean content of the mycotoxin sterigmatocystin (ST) in the mountainous area (5/8; 9. 14 μg/kg) were significantly higher than those in the hilly (0; 0) and plain areas (1/18; 1. 29 μg/kg) as well as in low risk area control samples (3/26; 0. 76 μg/kg). Detection rates of deoxynivalenol (DON) in mountainous and hilly areas (5/8, 4/8 respectively) were slightly higher than that in plain area (8/18), while the mean content of DON in the plain area was significantly higher (90. 45-170. 22 vs 50. 56 and 46. 45 μg/kg).Among the different aflatoxins, AFB1 was detected in samples from the two villages in the plain area for the subsequent two years. The mean content of AFB1 was 0. 0183μg/kg, and the highest level was 0. 0497 μg/kg. No AFB1 was detected in the samples from mountainous and hilly areas. AFG1 was detected in more than half of all the samples, and its concentration ranged from 8. 77 to 46. 51 ng/kg. No AFG2 was found in the samples. Thus, the results suggest that at present, fungal and mycotoxin contamination of foodstuffs in Cixian County are quite common.
