Is this statement true or false the maximuim efficiency of transformer is occured when iron losses is equal to full load copper losses?
Copper losses are directly related to loading of the transformer. Iron (core) losses are a result of magnetizing of the core of the transformer, and are relatively constant from no load to full load. With this in mind, it should be clear that the above statement is false. Maximum efficiency results with low core losses, and low copper losses. Copper losses cannot be helped, so it is important to minimize core losses to increase the efficiency of a transformer.
AnswerYes, it is perfectly correct -well, with the proviso that Transformers normally operate somewhat below full load and, so, are designed to achieve maximum efficiency somewhat below full load.A transformer's maximum efficiency does indeed occur when the copper losses and iron losses are equal. Unfortunately, the mathematical proof of this is too complicated to reproduce here, I suggest that you check out any reputable electrical engineering textbook.

What was the blue explosion in the sky that made a one minute power outage?
Either you're haunted by ghosts, Aliens are invading, your tranformer blew, or a temporal spatial anomaly occured and disrupted your power. I'm going to say it was probably something to do with your transformer or at least a fuse.

Difference row level and statement level triggers?
1) row level triggers can be identified by FOR EACH ROW is declared in the trigger declaration row level trigger is fired internally when any DML operation is occur in in any object like table it will fire for each row example: if any delete statement is occured for 30 records it will fire for 30 times. 2) Statement level triggers without declartion of FOR EACH ROW is statement level trigger is fired for every completion of statement example delete statement is occured for 3o records it will fire after the 3o records have been done
