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.

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.

∙ 8y agoFirst 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).

What is the kva for 138kv?
KVA is a measurement of power; kV is a measurement of voltage. You're asking "What is the power for voltage?", which makes no sense. Power = Voltage times current.
What is voltage in rotor of 11 KV AC generator?
Star (or 'wye') connected alternators have a phase voltage of 6.35 kV, and a line voltage of 11 kV. Incidentally, it's 'kV', not 'KV'.
Has Honduras three phase current?
Yes of course. The electrical grid in Honduras has 1,133 km of lines of 230 kV, 919 km of 138 kV, with distribution at 13.8 kV and 35.5 kV.
What is 11 kV single phase?
for USA, Canada and other countries running a 60 Hz supply service.A 11kV single phase line is one phase of a three phase system. The three phase system voltage is found by multiplying 11kV x 1.73. The three phase primary system voltage is 19kV. A transformer with a 11 kV primary can have a secondary of 115/230 depending on the internal connections in the transformer's case.For the UK11 kV is the standard three-phase h.v. distribution voltage in the UK, where it is a line voltage (i.e. it is the voltage measured between any pair of the three line conductors). A single-phase distribution transformer is connected between any two lines, so 'single-phase 11-kV' is simply a connection made between any two lines of an 11-kV three-phase system.As the primary windings of three-phase 11-kV distribution transformers are delta (3-wire) connected, the primary phase voltage is numerically equal to the primary line voltage (11 kV).
What is meant by 220 KV in 220 KV three phase Power Transmission line?
KV is the abbreviation for kilovolts. The prefix kilo means thousands, so 220 kv means 220 kilovolts, or 220,000 volts.

What is the Phase to phase voltage of 66KV earthed cable?
Nominal transmission and distribution voltages are line voltages. So '66 kV' is a line-to-line voltage. Note that there is no such thing as a 'phase-to-phase' voltage -the correct term is 'line-to-line'. Using the term, 'phase-to-phase', indicates a lack of understanding of a.c., which is not uncommon! Incidentally, the symbol is 'kV', not 'KV'.

What should be minimum distance between phase to phase for 11 KV?
127 mm for Indoor

What is the clearance in air required for 150 kv bil.?
Phase to phase clearance should be around 11.5 inches.
What is the formula for calculating the full load current of 11 kV generator?
Basically the formula is I = P / V where I = amps, P = power (kV) and V = volts for a single phase 11 kV genset the formula is 11000/400 = 27.5 amps max load. For a 3 PHASE GEN then 11000x0.8/400/3 = 7.3 amps per phase.
Which phase line used in raiway system?
25 kV single phase 50 Hz is common in railway systems in the UK.
Is US using 13.2kv in primary line distribution?
Yes, many parts of the US use 13.2 kV in primary line distribution systems. That is phase to phase. Phase to ground is 7620 V.
How much clearence between phase to phase in 10 kV supply?
The clearance depends on the voltage and would be defined in the electrical regulations in your country. <<>> The minimum horizontal spacing of conductors on the same supporting structure not exceeding 15 kV and not over a span of 50 metres (164 feet) is 400 mm (16 inches).
