How does and elevator work and what is its relationship to a splice in a cable?greenspun.com : LUSENET : Elevator Problem Discussion : One Thread
Can you please explain: (1) What does it mean if an elevator experience a power dip?
(2) If an elevator goes through a power dip would this mean that there would have to be a power outage?
(3) Do a splice in a cable cause a power outage?
(4) Can you translate a legal document that states the following: a splice failed in one of the the four 20kv underground cables?
(5) Would or could this previous question cause a power outage?
(6) What is the difference between a power interruption and a power outage?
(7) When or what causes an elevator brakes to kick in?
(8) Would an elevator shut down if a splice failed causing a dip in the power to the elevator?
(9) What does a voltage dip mean and is this considered the same as a power dip?
(10) Can excessive current cause an elevator to malfunction?
(11) If the voltage in an elevator is reduced what would be the result of such an voltage reduction and at what voltage level would an elevator actual be caused to fall?

strange question. r u having problems with your lift company-if so, should really ask them why these problems are occurring- I would be interested what other guys think

This is either one of two things . 1) a lawyer trying to understand some document that a power company or elevator company gave her or 2) someone trying to sue . I think #1 myself. Shirley if thats the case you need to get an elevator consultant and a electrical consultant . Because the things you ask there are a lot of possibilities and more info is needed to determine your needs .

Definately sounds like an attorney or a customer that's REALLY trying to get out of paying a BILL or some damages...
Think of it this way Shirley, what happens to your computer when subjected to the same power problems you describe ?
Call a consultant, the explanations your after are TOO in depth, and there are TOO many variables to give a factual answer...
Then you can sue the piss out of the power utility and the underground electrical contractor, because the elevator did just what it was supposed to do...

You've had a problem with the building power supply. If one of the phases has a high resistive path <
> and this phase supplies the current drawn by the Elevator, the drive machine current will vary in each phase. Such a variance may cause damage to the Drive machine, the Drive VVVF unit if one is fitted and quite possibly to the Micro psu board if you have a Microprocessor controlled Elevator. An elevator is usually fitted with both low voltage and phase failure sensing devices but not devices to sense any other abnormalities in the building supply. In my opinion such an abnormality is the responsibility of the Power Utility provider. A chartered Electrical Engineer will provide more info. Hope this helps

OOH, OOH, HEY, SHIRLEY! I THINK I KNOW THAT ELEVATOR. UM...IT'S PROBABLY ONE OF THEM SCRAPPED ONES THAT WERE TAKEN OUT OF SERVICE FROM THEM OLD OFFICE BUILDINGS DOWNTOWN. THEY HAD TO GET RID OF 'EM OR LOSE THEIR INSURANCE OR SOMETHING. ARNIE LEDBETTER OWNS THE SCRAP/SALVAGE COMPANY THAT ENDED UP WITH THEM AND SOLD ONE TO J.B. GLANDSHANKS WHO MADE SOME QUICK CASH INSTALLING IT IN YOUR BUILDING. IT'S OK THOUGH,...REALLY! JUST TOSS IN A COUPLA MATRESSES AND MAKE HELMETS, ELBOW AND KNEEPADS A STANDARD REQUIREMENT AND YOU WON'T HAVE ANY PROBLEMS AT ALL...PROBABLY. OR ,IF THAT'S NOT THE SAME ELEVATOR I THINK IT IS, IT'S NO BIG DEAL,...IT'S SOMEONE ELSE'S PROBLEM, RIGHT? YA KNOW WHAT, SHIRLEY? I'LL BET THE POWER COMPANY IS JUST HAVING SOME FUN F---ING WITH YA.

P.S. SHIRLEY, PLEASE TAKE SOME COMFORT IN KNOWING "IF GOD ACTUALLY MEANT FOR US TO USE ELEVATORS,...WHY WOULD HE HAVE PUT IN STAIRS" SO, THEN....IT'S REALLY NOT MY FAULT, EVER....AT LEAST PART OF SOME OF THE TIME. REMEMBER OUR MOTTO AT MAKE-DO, "IF WE CANT FIX IT..WE'LL GIVE IT TO J.B. GLANDSHANKS." MILTON, ETC.ETC.... P.S. AGAIN. I JUST WANNA ASK YOU SHIRLEY, THAT IF YOU MIGHT KNOW OF ANYONE WHO COULD USE A REALLY GOOD DEAL ON AN ELEVATOR, J.B. STILL HAS THE ONE LEFT. IT'S MABIE NOT QUITE IN AS GOOD OF CONDITION AS YOURS,(he has the thing laying on it's side using it as a trash/scrap compactor) BUT FOR EIGHTY BUCKS,OR SO, WHO'S GONNA BE CHOOSEY RIGHT? M.N.

I reckon that if one needs to ask these questions, then you are the wrong person for the task. It needs saying sometimes, but isn't it blooming obvious that when the electric goes off, the appliances ( & lifts) generally stop working. An interuption is usually a momentary failure. An outage is often a prolonged failure. Both can mean the same thing though, Outage is not a recognised term. Interruption is accurate, and the time span should be specified. Doesn't anyone understand English nowadays? Surely the grammar on this document is too poor for a legal person anyway. There are too many colloquialisms (" slang") for an educated person to have compiled this. "Kick-in" is hardly the technical term one would use to a customer. (or lawyer)
