IV.2. Circuit Breakers & Relays

By BlueCadet3 at 1:05 pm on Friday, February 5, 2010

Circuit breakers are also commonly used to disconnect faults from the system. The breakers are usually tripped by means of relays that detect faults with current transformers (CTs) and voltage transformers (VTs). As mentioned, the installation of DG will change fault currents throughout the system, which will then affect the ability of relays to properly detect faults. The radial distribution feeder shown in Figure IV.4 can be used to illustrate the problems encountered by relays when DG is present (assume standard overcurrent relays are used).

When no DG is connected, the relay R2 should trip for faults at Bus 3 but relay R1 should not. For faults at Bus 2, R1 would trip. Both relays would see the same fault current for a fault at Bus 3, therefore the relays must be coordinated so that R2 will trip faster. Relay coordination is accomplished using the current tap settings (CTS) and time dial settings (TDS) of the relays. In this case, the TDS of R1 would be set to a higher value than R2 so that R2 would trip faster for faults at Bus 3. R1 provides backup to R2 in this case; if R2 fails to operate quickly, R1 will still operate after a certain delay referred to as the coordination time interval (CTI). Figure IV.5 shows a typical graph of how these settings would appear for coordination in this case.

‘ghost stories’

By rottenrocks at 9:50 pm on Thursday, February 4, 2010

the title is just off the top of my head, but I dig how it came out…got to thank besatree/billypilgrim/lightfighter for bumpin in my headphones when making this though. you made it all the more comforting for me. and it is a crappy copy photo of the print, just because of one of the shadows on the corner. but whatever, gotta love chance.

the struggle continues

This is my new photo, more to come. I am super stoked off of it. And if anyone knows how to rotate an image to put it on here from a mac computer, I am up for all suggestions.

Biting Back

By besatree at 9:15 am on Wednesday, January 20, 2010

What a scam… these demands from taxman. Don’t pay and your face connects with backhand. Get slammed by Uncle Sams clan if you’re not married, don’t have a kid and don’t own land.
No plan was alright by me, but I got stifled with a rifle in-between my teeth. Trying to speak seems like such a bleak thought, can’t fight when path’s been traveled and the battles been lost.
The double cross is difficult while double loss is typical, fist full of dollars gets pecked at until invisible. It’s miserable, these individuals all turned into vegetables. It never crossed my mind I’d be swindled by some edibles.

wrap it up.

I’m not a real rapper cuz I’ve got a nine to five, & since I show up promptly nearly daily I survive.
I’m not a real rapper cuz I wasn’t exposed to hits, was hanging with the punk rock, screamo, grind and crusty kids.
I’m not a real rapper cuz my fans are all my friends, I’m giving out cds freely, essentially handing out my ends.
I’m not a real rapper cuz my aim ain’t fame or gains, I merely rap to explore the map that’s plastered to my brain.
I’m not a real rapper cuz my paragraphs make no sense, yeah its true, its not just you, even I’m lost on what was written.
I’m not a real rapper cuz apparently appearances count, for more than a dot percentage of what the music’s all about.
I’m not a real rapper cuz I ain’t dope enough for tv, gonna have to stick to low-budget and love it like Drowning with K.B.
I’m not a real rapper cuz I started way to late. Whoops! My bad, sorry for that…yo Ma, can we change my birth date?

I TRIED TO SAVE AS WIDGET TO MYSELF, BUT TO MUCH WINE AND CONFUSION GOT IN THE WAY.

You know that point.
Where you want to tell her how much you like her.
And you finally get the courage after she says:
“I will call you or you will call me”
I envision myself walking out the door,
Turning back and saying
“I have to be honest, and please wait till the end,
but I really like you. And if that means our friendship is gone
then I take it back.
Because that means more than I can ever even comprehend,
Even in my drunken state.
Frienship still matters….but I like/love you”
(but it don’t mean a damn thing in the world(the lovelife, that is))
if it means loosing you.
In conversation or in the drunken walks home
From shows to good to be true,
to your apartment
Sleeping on your floor,
and crazies
That make this place what it is.

Dresden Part1

By Chelovek at 1:40 pm on Wednesday, December 30, 2009

The look in her eye told him it was time to dance; his fancy footwork amazed all ablaze but pleased none who were on the other side of the world. Adorned with Buda dolls and Dresden dreams he caught fire with the relatives and arose like a phoenix, spreading his arms above his head for theatrical effect. The streets seemed to bend with the heat and it was a frightful sight indeed. The lack of emotion took precedence over the flesh shedding from bone.   Far off lakes looked lopsided and more alluring from within so he lay down and tried to count the stars forgetting to count the one he saw sinking out of sight earlier.  He placed his fingers over tiny spots of light squinting one eye, envisioning his atoms taking shape and joining other matters of matter.  He thought of how he would have no consciousness since existence would no longer be “there” upon his demise. Thoughts of “Their” legs touching under the sheets with feet overlapping and gropes and moans shrouded in sweat. Speakers played a track over and over again in his head, a soothing voice speaking of all things good in the world in 5 second intervals.   Then, there were no ears to hear anymore, only an empty void and a touch of ecstasy pinging away in the deafness of it all.  This thought whimpered on, providing a semblance of what he thought was what he experienced.  His mind wandered further creating new crevices of joy, scenarios that never took place but were just as real to him nevertheless. It was just a look outward through the flames.

fighting through the days
simply trying to understand
but even that one over there
he doesn’t understand
and why should i
should i struggle

The Great In Between

By BlueCadet3 at 12:39 pm on Sunday, November 29, 2009

Back in the seat.
The glass divide down all the way, let the wind hit the sails of my face. Got the pooch by my side, flying face-first through the world of Man, ears flapping like he never wants to come down.
It’s a steel cage of freedom we ride; smoothly gliding away. The sweet release of departure hangs thickly on my lips. I give a lick and relish the taste of solidarity with my self.
There is behind me. There is ahead of me. But the serene bliss I feel now can only be found in between. I never want to arrive. I never wish to farewell again. I want only to be always in this comfortable state of transition. May this ride never end.

Never end.
