tree has lots of watere absorbed in it... air under tree is
also humid... and it is advisabl not to stand under trees
durng lightning

combining all.... tree is a conductor... or not???

Answer / abdul basit

tree is not a conductor, according to the definition of
conductor. But in case lightening current may pass from it
due to LARGE POTENTIAL. Secondly if a gtransmission line
fall on it then it would act as an ground and Line to
Ground case occurs.
CONCLUSION:
Not a GOOD Conductor, but can afect the power system system
due to its natural behaviu=our(construction)

Answer / sparks

That is a very interesting question to which my old teacher
had the best answer.
Every conducts electricity some just more that others.
Although a tree does compose of water and other elements and
is the most likely spot to be hit by Lightning does not make
it a good conductor more like a good resistor.

The definition of a good conductor depends on how their
music sounds.... wait wrong conductor, a good conductor will
have little to no resistance to electrical current.

so if you want to experiment, and would not advise this at
all, connect a tree in series to a large load and hit the
switch with an ammeter to see what the difference is with
and with out the tree in the circuit. my bet will be the
resistance of the tree will be so great that there will be
no flow of current. (Low voltage (230V) up to 13kw load)....

I did oil BDV test of 1600 KVA trafo 20KV/400V as per IEC 156. Result is 1) 58 KV 2) 58 KV 3)40 KV 4) 50 KV 5) 58 KV 6) 18 KV. Avr is 47 KV. Can we say oil is still ok even in the 6th test BDV is 18 KV ?

need to make a report. Need to choose a 3phase induction motor. Load conditions motor will operate in : Maximum Load: 30 Kw Speed: 2950 rpm Ambient temp: 20 cent Supply voltage: 440V Frequency: 50Hz need to look for the safety factor when choosing the motor, went through catalouge found a few, but dont know how to choose the safety factor allowing an extra load something above 30 KW to avoid any harm.
