Post possible questions for Power Factor Panel FAT / SAT
we have an energy meter in a capacitor bank panel, So should we consider it's readings as energy consumption on daily basis. (when capacitor bank doesn't have any energy losses)
This is reqd for a 1MW Solar power plant..We have 2DC outputs from the solar panels Connected to 2INVERTOR panels.. Output from invertor is 3ph,280v,500kva,50hz.These are connected to individual ACB.This has to be stepped up to 11KV ,1250KVA SYSTEM.Now can I use (1) one more ACBTO GIVE A COMBINED OUTPUT OF 1000KVA,280V & STEP UP THE OUTPUT BY USING a single two winding 3 ph transformer 11kv/1250kva. or (2)use the two outputs and connect to one three winding transformer of above rating..Pls suggestwith details.
What is time response of the control system?
Can anyone explain me about the RLC based Impulse high voltage generator and how to and operation of Series resonant High voltage reactor...?
if we look on phasor of the transformer vaoltage is 180 oppsite at primary and the secondary so to improve a power factor is secondary should kept negative to improve it primary side means is -.90 became +.90 at other side
wat system call?
Why in metering Ct for ammeters ct secondary side is grounded for each Ct but not in case of CBCT (Core balance current transformer)..kindly some1 highlights the reason..is it because net flux is zero?

What is 11 N1 and 12 N2 in single phase Transformer ?
while doing high voltage test on 11kv/433 distribution transformer why we only give 28 kv on hv side and 3kv on lv side for power transformers what is the value what factors it depends
