What is the kv phase to phase for 13.8kv?

Answer 1

yes

Answer 2

There is no such thing as a 'phase-to-phase' voltage; the correct term is 'line-to-line' voltage. Whenever you mention a value of voltage for a three phase system, it is considered to be a line-to-line voltage unless it is stated clearly that this is phase voltage (line to neutral) voltage.

(The reason that there is no such thing as a 'phase-to-phase' voltage is because phases exist between, or 'across', line conductors or between a line conductor and a neutral.) That is a world wide practice for electrical power engineers.

Answer 3

7960 volts

<<>>

A voltage of 13.8 kV is a phase to phase voltage on a 13.8kV delta system. Phase to ground wye connection on this system would be 7976 kV. If the 13.8 kV is phase to ground connection then the phase to phase voltage would be 23.8 kV.

Answer 4

First of all: 'line' and 'phase'. The conductors that connect a three-phase load to a three-phase supply are called 'line conductors' or, simply, 'lines'. The individual three-phase loads are 'phases'.

So voltages measured between line conductors are called 'line voltages' whereas voltages measured across phases (individual loads) are called 'phase voltages'. THERE IS SIMPLY NO SUCH THING AS A 'PHASE-TO-PHASE' VOLTAGES.

Similarly, currents passing along line conductors are called 'line currents', whereas currents passing through individual loads (phases) are called 'phase currents'.

For delta-connected systems, a line voltage is numerically identical to a phase voltage, but we still retain the two terms so as to make it clear where the voltages are being measured.

For star-connects systems, a line current is numerically identical to the phase current, but we still retain the two terms so as to make it clear where the currents are being measured.

Finally, to answer the question, 13.8 V is a line voltage (line-to-line voltage).
