Hello Can I use step up HV transformer 440/4160V as a step
down? Thanks

Answer / milinda4p
theorically it is yes....
but thickness of the wires are different in two sides
here 440/4160 means the thickness of the wires @ 440 is much
higher than 4160 side(because the current is decreased when
step up)..so if supply @ other side i:e supply 4160v then
the thickness of the wire may not be sufficient enough to
handle the current @ that side...
so it mightnotbe possible

Answer / syam mohan
if we apply 4160v at the 4160v side of the 440/4160v
transformer 440v will be produced on the 440v side

Answer / abdul
Thikness of conducter is not an issue here. current flows
only when connect a load at low voltage side. Current will
be still very less at 4160 side.

Answer / ravinder
this is only possible when transformer is unloaded because
if we connect load winding,s of T/F ARE BURNout this
mightly be posibble

how does directional relay work incase of ac ?
If 24 KVA AVR having Input voltage 200-400v, Output voltage 415+-1%, what will be the voltage if Load is 13A.
In power generator sets, when they are coverted from 50hz to 60hz, the kva rating after conversion increases. For example, the manufacturer of a perkins 200kva @ 50Hz generator set has mentioned it to become 220kva after converstion to 60hz. What is the relation between the frequency & the KVA rating. Any formula please.
How Can we calculate current carrieng capacity of Copper Bus-Bars and Alluminium Bus-bar
As we use capacitor bank in 3ph ckt to improve PF, can we use capacitor in single ph domestric use, in house we have Fan,Mixer,electric cooker,iron,tube choke they also lag the system,because it is inductive load. if it is possible to improve PF of single ph system-- if yes- type of capacitor to be used,connection diagram, working in detail. if no-- list it.

What will be the size of cable required for 5.5 KW motor ( Full load current 10 Amps approx.), Starting current with DOL is 120 Amps. Aprrox. Short circuit current with LLLG fault is 2000 Amps Approx.
it is clear that volts equal to the current as per ohms law. is it appliable to the AC power or only for DC. if it is appliacable to AC in transformers when voltage increases the voltage decreases ????? why??????????????
