down conductor การใช้

For this reason, the down conductor route is kept short, and any curves have a large radius.
The technique has even been adapted for more advanced uses, such as laying down conductors and resistors in multi-layer circuits using thin ceramic layers as the substrate.
The air terminals are typically arranged at or along the upper points of a roof structure, and are electrically bonded together by bonding conductors ( called " down conductors " or " downleads " ), which are connected by the most direct route to one or more grounding or earthing terminals.
Such overloads should sound an alarm at the control center, and the operator should take action, such as closing a bus tie or correcting an abnormal switching configuration due to an oops error ( OOPS, WE PUT THE TOWN ON A 1 LINE FEED WHEN IT TAKES 3 LINES TO SUPPLY IT . ) Some utilities have " transformer overload relays " which do trip a transformer when it is so overloaded as to exceed its short term emeregency rating, because transformers can take months to replace, much longer than burned down conductors.
