This paper investigates the effects of breaks in bonds, breaks in the earthing system and breaks in earth wire on the rise of the earth potential (EPR) in a substation and at the transmission tower bases using various models of an L6 tower. Different approaches were adopted to examine the integrity of the earthing system and the terminal towers. These effects were investigated to see the associ...

This paper describes a new, high-speed protection for EHV transmission lines. The presented scheme also performs well on series compensated lines. The High speed distance protection (ZMFPDIS) function is a six zone full scheme protection with three fault loops for phase-to-phase faults and three fault loops for phase-to-earth faults for each of the independent zones, which makes the function su...

Fault isolation is the process of reasoning required to find the cause of a system failure. In a model-based approach, the available information is a model of the system and some observations. Using knowledge of how the system generally behaves, as given in the system model, together with partial observations of the events of the current situation the task is to deduce the failure causing event...

A distributed system is fault-tolerant if it continues to perform correctly even when a subset of the processes becomes faulty. Faulttolerance is highly desirable but often difficult to implement. In this paper, we investigate fault-tolerant synthesis, i.e., the problem of determining whether a given temporal specification can be implemented as a fault-tolerant distributed system. As in standar...
