An industry outsider (say, a juror) might consider the variation in passenger assistance within the public transportation industry alarming. Exploring a single theme like boarding and alighting illustrates the extremes
Many people just take for granted that something is just going to work, and in many cases assume that it will work forever. One such device that does not get enough attention is the Ground Fault Circuit Interrupter (GFCI). Simply put, a GFCI is a protective device that compares the current flowing on the hot and neutral wires of the circuit and will "trip" to disconnect power to the circuit if a small imbalance of current is detected. The imbalance of current is an indication of a dangerous alternate path for the current to flow from a damaged line cord or a fault inside an appliance and constitutes a shock hazard to a person.
Ideas are stored in the human mind as a neural pattern. These same ideas can be stored in a computer through an organization of memory bits. In both cases the memory is electrical in nature. Ideas are transferred between people by converting the information in memory to electrical impulses that operate our vocal cords or the fingers on our computer keyboard.
Abstract — Severe weather events such as ice and tropical storms routinely cause extensive damage to electrical distribution systems. Much of the damage and service loss can be attributed to trees. Events where service restoration spans days or weeks are generally closely examined through regulator directed hearings. Even when no specific actions are subsequently
Abstract - For power transmission systems compliant with safety codes and reliability standards there remains a risk of tree-caused interruptions from the in-fall of trees from outside the right-of-way. This paper reports on the quantification of tree exposure outside National Grid’s transmission corridors and examines the variables impacting the risk of a line contact by trees
