Path 65 (with respect to earth.)

  

"The Pacific DC Intertie 

 (also called Path 65)    



"The LaPerm is a breed of cat.  

"A LaPerm's fur is curly (hence the name "perm"), with the tightest curls being on the throat and on the base of the ears. 

 LaPerms come in many colors and patterns. LaPerms generally have a very affectionate personality."







is an electric power transmission line that transmits electricity from the Pacific Northwest to the Los Angeles area using high voltage direct current (HVDC). 

 The line capacity is 3.1 gigawatts, which is enough to serve  

two to three million Los Angeles households  

and represents almost half of the Los Angeles Department of Water and Power (LADWP) electrical system's peak capacity." 


"The intertie originates near the Columbia River at the Celilo Converter Station of Bonneville Power Administration's grid outside  

The Dalles, Oregon and is connected to the Sylmar Converter Station north of Los Angeles, which is owned by five utility companies and managed by LADWP.  

The Intertie can transmit power in either direction, but power flows mostly from north to south." Mmmm 


"By 1961, US president John F. Kennedy authorized a large public works project, using new high voltage direct current technology from Sweden. The project was undertaken as a close collaboration between General Electric of the US and ASEA of Sweden. 

 Private California power companies had opposed the project but their technical objections were rebutted by Uno Lamm of ASEA at an IEEE meeting in New York in 1963. When completed in 1970 the combined AC and DC transmission system was estimated  

to save consumers in Los Angeles approximately 

 US$600,000 per day  (1963 mind you)

by use of cheaper electric power  

from dams on the Columbia River. 


"Any time the Intertie demand lessens, the excess is distributed elsewhere on the 

 western power grid  

(states west of the Great Plains, including Colorado and New Mexico)."

The first phase of the scheme, completed in May 1970

 used only mercury-arc valves in the converters. 

 The valves were series connected in three six-pulse valve bridges for each pole. The blocking voltage of the valves was 133 kV with a maximum current of 1,800 amperes, for a transmission rating of 1,440 MW with a symmetrical voltage of 400 kV  

(with respect to earth.)


Each converter station housed six mercury arc valves groups, consisting each of seven valves, for a total of 42 valves in each converter. 

 The valves had a width of 7.1 feet (2.15 m), a height of 10 feet (3.2 m) and a length of 11 feet (3.5 m) and weighed 14,000 pounds (6,400 kg). 

 Each valve contained 

 1.1 litres  

(37 US fl oz) mercury, 

 with a weight of 33 pounds " 


"1972: 

 After the Sylmar earthquake, 

 the Sylmar Converter Station had to be 

 reconstructed due to extensive damage. 


1993: 

 One pole of the Pacific Intertie Expansion converter station at Sylmar was completely destroyed by fire. 

 The converter was replaced in 1994–1995 by Siemens. 


1994:  

After the Northridge earthquake, the Sylmar Converter Station had to be 

 reconstructed due to extensive damage."

"The breed was named after their curly coat which bears resemblance to a shaggy perm. 

 The name follows the Chinookan tradition of adopting French words  

while incorporating the definite article to create a new word; 

 for example, in Chinook Wawa, 'pipe' is lapeep and 'apple' is lapom,  

(la pipe and la pomme, respectively, in French)". 



It has nothing to do with Electrification 

Or LA, California 

Or frizzy heads from static  .


"The LaPerm emerged around the early 1980s as a spontaneous mutation of cats bred for pest control.  

The breed founders were Linda and Richard Koehl from The Dalles, Oregon, whose cat Speedy gave birth to a curly-coated kitten, named Curly, from whom all LaPerms descend.  

The Koehls allowed a free-breeding colony of curly-coated cats to develop over a period of ten years before making contact with members of the cat fancy and initiating a formal breeding program."

'In 1893, the name changed to "Sylmar", a fusion of two Latin words for "forest" and "sea" in reference to the large number of olive trees that once covered the area." 


The foothills of the San Gabriel Mountains were transformed in the late 1890s by the Los Angeles Olive Growers Association

 In 1894, up to 1,700 acres of land were planted with olives trees and by 1906, the property had become the largest olive grove in the world


Tipped off by a Sylmar resident, dozens of investigators from at least five police departments and three federal agencies raided a warehouse at 12898 Bradley Street, on September 29, 1989, and seized some 

 21.4 tons of cocaine and $10 million in cash. 

 It was the largest confiscation of the drug in history, estimated at $6.9 billion, enough for 1.38 billion doses.
