Find the leak and repair it. There's not much else to say!
it is a pit which is used to drain leakage oil of transformers .AnswerIt's a walled area, surrounding a transformer, intended to contain any oil leakage from a transformer.
If you have a large power transformer that is leaking oil, do NOT touch it! Older transformer oil contains PCB's which are extremely toxic!! Get a licensed firm to test the oil for PCB's and repair or replace the transformer. Don't fool around with this! PCB's are a serious danger to you and others. Do not let this go. Get it fixed right away!
leakage rfactance
On installed transformer a test is performed to check weather it has any oil leakage or not, the test is called pressure test, more precisely pressure leakage test.
oil leakage
Leakage reactance is useful for limiting the short circuit current in transformer and generators. therefore normally the reactance of transformer varies for 4.5% for distribution transformer to 12.5% for 400KV class.
What is the definition of earthing and how it works?
In low voltage and electronics Leakage Current is any current that flows when the ideal current
Transformer oil is pure insulating oil.
to cool a winding of transformer and it is a insulating material and transformer oil is a purifing oil
Nytro libra is an uninhibited transformer oil
Nice Question: It is done for 2 basic reasons: 1. If a flat or a concrete surface is used then there are chances of water accumulation during rain which must be avoided in Yards. 2. Lets suppose if there is any oil spill or leakage in transformer, then the oil can never got accumulated on surfaces. Instead, it will seep from gravel into bottom thereby minimizing chances of fires.
