Dear Friend
the R = Pl/A is not used to measure earth resistance. is is
used to measure conductor resistance.
to measure earth resistance. We need an DC power source,
Ampere meter & volt meter & the formula R = V/I
The earth resistance testers are available in market, they
are been used by three leads on connected to the test
object & Current & Potentional probes are conneceted 20 &
10 meters away from object under test.

i have a 4 Mva transformer 34.5 kv / 480-277 v and i used 2 parallel 3200 amp bus duct for the secondary feeder using 3 ply of bus bar ( 3/8" x 5" ) as a common where the flexible link terminated and 6300 amps breaker for the main, the lower bus duct reaches 70 degrees and the upper bus duct reaches 55 degrees when i used thermal scanner. why the temperature is not balance when the load reaches 3600 amps.

A powerplant has 8 gensets operating in grid parallel mode. In one genset sometimes there is pf variation and kvar variation. The plant operates in pf mode. When this variation is observed the load is stable, voltage is also stable, freq and genset speed is also stable. How will you check the functioning of pf card. What shall be the ideal output vdc of the pfc, from there it is input to AVR?
