Is line voltage or phase voltage mentioned on transformer nameplate?

It depends how they are connected. If they are connected between line conductors then they are measuring line voltages. If they are connected across phases then they are measuring phase voltages.

What is the current of 1MVA transformer?
This depends on the voltage, and whether it is a three phase or single phase transformer.
How the voltage is induced in a single phase transformer?
The changing magnetic flux in the iron core of the transformer induces a voltage in the windings.
How do you establish no of turns in both high voltage and low voltage windings of a 3 phase transformer?
Through the use of the basic transformer voltage equation.
What is the angle between no load current and the applied voltage in an ideal transformer?
A: Transformer by itself goes not alter the phases the output can be in phase or out of phase depending how you look at it.
Why does a phase in secondary side in distribution transformer give low voltage?
transformer is busted; if input voltage is normal you have short circuit or open circuit somewhere

What is the voltage phase shift between primary and secondary line voltages in star-delta transformer connection?
The voltage phase shift between primary and secondary connections in a transformer is 180 electrical degrees.

What is the procedure to polarity test a 3 phase transformer?
A 'polarity test' is conducted on a single-phase transformer, not a three-phase transformer (or transformer bank). The polarity of a single-phase transformer being important if two transformers are to be connected in parallel, or three transformers are going to be connected to form a three-phase transformer bank.'Angular displacement' is, to a three-phase transformer, what 'polarity' is to a single-phase transformer. So you really should be asking about angular displacement, rather than polarity. Angular displacement, or 'phase displacement', is the angle by which the secondary line voltage lags the primary line voltage.Angular displacement can be determined either by drawing a phasor diagram of the three-phase connection and measuring it, or by looking up the connection in a vector-group chart/table -you would nor normally 'calculate' angular displacement.
In a 3-phase high voltage star-star connection 140KVA transformer and load phase voltage is 115v and frequency is 400hz what is the total load current?
Maximum load current on a 140KVA, three phase transformer when the output voltage is 115 v phase to phase is: 140kva / sqrt (3) / 115 = 703 Amps. frequency does not matter here.
What transformer do you need if you have primary voltage of 600 3 phase and require 240 volt 1 phase?
A single phase 600 to 240 Volt transformer using two phases of the three phase primary.
Why would you use a three phase transformer in place of a single phase transformer?
the necesscity of two three phase transformers operating in parallel are as follows...if the one transformer fails to give supply,then another transformer can be used in parallel and hance,continuity of supply can be maintained.one transformer can be easily take out from the supply for repair & maintanance.if the load on the substation increases beyond the rated values of transformer, then another transformer can be used to share rhe load of the substation.
Voltage across Neutral and earth for a 3 phase auto transformer?
A grounded neutral will be at earth potential. A floating neutral will be at a voltage dependent upon the voltage imbalance between phases, and the design of the transformer.
Can you convert three phase 480 volts to single phase 110 volts?
If you have a 220v three phase delta system, the phase-to-phase voltage is 220v single phase; hence, no conversion is necessary. Don't worry about 220-240v rating, the voltage rating is nominal. Your 110v single phase has actually already be taken from a center-tapped transformer on your three phase system.
