The pantograph and the contact line constitute a pair of special friction pairs, between which
there are mechanical wear caused by friction and electrical wear under the action of strong …

Control of the maglev system is one of the most significant technologies of the maglev train.
The common proportion integration differentiation (PID) method, which has fixed control …

Inspection of partial discharge before contamination flashover is of great importance for
preventing exterior insulation accidents. In this study, a new method for identification of …

Partial discharge detection before insulator flashover plays a significant role in external
insulation fault diagnosis. Ultraviolet (UV) detection has the advantages of non-contact …

In this paper, we mainly prove some congruences involving Apéry-like numbers S n = ∑ k =
0 n ( n k ) ( 2 k k ) ( 2 n − 2 k n − k ) : Let p>3 be a prime. Then S p ≡ S 1 + ( − 1 ) ( p − 1 ) / 2 …

The detection of polluted insulator discharge in humid environments is crucial for power
system examination. In this article, we propose novel classification and evaluation methods by …

Maglev train is a modern rail vehicle with low energy consumption, low noise and high
comfort. Due to the monitoring of the running state of the train during the operation and …

With the gradual deterioration of atmospheric environment, pollution accumulation causes
the increase in flashover accidents, which seriously threatens the safety and stability of power …

Internal overheating and excessive micro-water content can lead to the degradation of insulation
performance in gas insulated switchgear (GIS) air chamber and cause faults. In order to …

Pollution flashover of insulators is one of the common faults in the field of power transmission
and transformation. In order to improve the reliability of non-contact detection of insulator …
