11 Brennan, Louis
[br]b. 28 January 1852 Castlebar, Irelandd. 17 January 1932 Montreux, Switzerland[br]Irish inventor of the Brennan dirigible torpedo, and of a gyroscopically balanced monorail system.[br]The Brennan family, including Louis, emigrated to Australia in 1861. He was an inventive genius from childhood, and while at Melbourne invented his torpedo. Within it were two drums, each with several miles of steel wire coiled upon it and mounted on one of two concentric propeller shafts. The propellers revolved in opposite directions. Wires were led out of the torpedo to winding drums on land, driven by high-speed steam engines: the faster the drums on shore were driven, the quicker the wires were withdrawn from the drums within the torpedo and the quicker the propellers turned. A steering device was operated by altering the speeds of the wires relative to one another. As finally developed, Brennan torpedoes were accurate over a range of 1 1/2 miles (2.4 km), in contrast to contemporary self-propelled torpedoes, which were unreliable at ranges over 400 yards (366 in).Brennan moved to England in 1880 and sold the rights to his torpedo to the British Government for a total of £110,000, probably the highest payment ever made by it to an individual inventor. Brennan torpedoes became part of the defences of many vital naval ports, but never saw active service: improvement of other means of defence meant they were withdrawn in 1906. By then Brennan was deeply involved in the development of his monorail. The need for a simple and cheap form of railway had been apparent to him when in Australia and he considered it could be met by a ground-level monorail upon which vehicles would be balanced by gyroscopes. After overcoming many manufacturing difficulties, he demonstrated first a one-eighth scale version and then a full-size, electrically driven vehicle, which ran on its single rail throughout the summer of 1910 in London, carrying up to fifty passengers at a time. Development had been supported financially by, successively, the War Office, the India Office and the Government of the Indian state of Jammu and Kashmir, which had no rail access; despite all this, however, no further financial support, government or commercial, was forthcoming.Brennan made many other inventions, worked on the early development of helicopters and in 1929 built a gyroscopically balanced, two-wheeled motor car which, however, never went into production.[br]Principal Honours and DistinctionsCompanion of the Bath 1892.Bibliography1878, British patent no. 3359 (torpedo) 1903, British patent no. 27212 (stability mechanisms).Further ReadingR.E.Wilkes, 1973, Louis Brennan CB, 2 parts, Gillingham (Kent) Public Library.

valeur maximale du courant électrique qui peut parcourir en permanence, un conducteur, un dispositif ou un appareil, sans que sa température de régime permanent, dans des conditions données, soit supérieure à la valeur spécifiée
[IEV number 826-11-13]Ampacity, the term is defined as the maximum amount of current a cable can carry before sustaining immediate or progressive deterioration. Also described as current rating or current-carrying capacity, is the RMS electric current which a device can continuously carry while remaining within its temperature rating. The ampacity of a cable depends on:
- its insulation temperature rating;
- conductor electrical properties for current;
- frequency, in the case of alternating currents;
- ability to dissipate heat, which depends on cable geometry and its surroundings;
- ambient temperature.
Electric wires have some resistance, and electric current flowing through them causes voltage drop and power dissipation, which heats the cable. Copper or aluminum can conduct a large amount of current before melting, but long before the conductors melt, their insulation would be damaged by the heat.
The ampacity for a power cable is thus based on physical and electrical properties of the material & construction of the conductor and of its insulation, ambient temperature, and environmental conditions adjacent to the cable. Having a large overall surface area may dissipate heat well if the environment can absorb the heat.
In a long run of cable, different conditions govern, and installation regulations normally specify that the most severe condition along the run governs the cable's rating. Cables run in wet or oily locations may carry a lower temperature rating than in a dry installation. Derating is necessary for multiple circuits in close proximity. When multiple cables are near, each contributes heat to the others and diminishes the amount of cooling air that can flow past the individual cables. The overall ampacity of the insulated conductors in a bundle of more than 3 must be derated, whether in a raceway or cable. Usually the de-rating factor is tabulated in a nation's wiring regulations.
Depending on the type of insulating material, common maximum allowable temperatures at the surface of the conductor are 60, 75 and 90 degrees Celsius, often with an ambient air temperature of 30°C. In the U.S., 105°C is allowed with ambient of 40°C, for larger power cables, especially those operating at more than 2 kV. Likewise, specific insulations are rated 150, 200 or 250°C.
The allowed current in cables generally needs to be decreased (derated) when the cable is covered with fireproofing material.
For example, the United States National Electric Code, Table 310-16, specifies that up to three 8 AWG copper wires having a common insulating material (THWN) in a raceway, cable, or direct burial has an ampacity of 50 A when the ambient air is 30°C, the conductor surface temperature allowed to be 75°C. A single insulated conductor in air has 70 A rating.
Ampacity rating is normally for continuous current, and short periods of overcurrent occur without harm in most cabling systems. The acceptable magnitude and duration of overcurrent is a more complex topic than ampacity.
When designing an electrical system, one will normally need to know the current rating for the following:- Wires
- Printed Circuit Board traces, where included
- Fuses
- Circuit breakers
- All or nearly all components used
Some devices are limited by power rating, and when this power rating occurs below their current limit, it is not necessary to know the current limit to design a system. A common example of this is lightbulb holders.

When multiple cables are near, each contributes heat to the others and diminishes the amount of cooling air that can flow past the individual cables. The overall ampacity of the insulated conductors in a bundle of more than 3 must be derated, whether in a raceway or cable. Usually the de-rating factor is tabulated in a nation's wiring regulations.
Depending on the type of insulating material, common maximum allowable temperatures at the surface of the conductor are 60, 75 and 90 degrees Celsius, often with an ambient air temperature of 30°C. In the U.S., 105°C is allowed with ambient of 40°C, for larger power cables, especially those operating at more than 2 kV. Likewise, specific insulations are rated 150, 200 or 250°C.
The allowed current in cables generally needs to be decreased (derated) when the cable is covered with fireproofing material.
For example, the United States National Electric Code, Table 310-16, specifies that up to three 8 AWG copper wires having a common insulating material (THWN) in a raceway, cable, or direct burial has an ampacity of 50 A when the ambient air is 30°C, the conductor surface temperature allowed to be 75°C. A single insulated conductor in air has 70 A rating.
Ampacity rating is normally for continuous current, and short periods of overcurrent occur without harm in most cabling systems. The acceptable magnitude and duration of overcurrent is a more complex topic than ampacity.
When designing an electrical system, one will normally need to know the current rating for the following:- Wires
- Printed Circuit Board traces, where included
- Fuses
- Circuit breakers
- All or nearly all components used
Some devices are limited by power rating, and when this power rating occurs below their current limit, it is not necessary to know the current limit to design a system. A common example of this is lightbulb holders.
