What are the volts per phase on a 240 volt system?
By 'volts per phase', I assume you mean 'phase voltage' as opposed to 'line voltage'?It depends on the country in which you live. In North America, for example, the secondary output of a three-phase distribution transformer typically delta connected, 240 V corresponds to both the phase and line voltages.In other countries, where a three-phase distribution transformer's secondary is wye connected, 240 V is typically a phase voltage and 415 V is a line voltage.
How can three types of supply be obtained from the secondary side of a delta star transformer where the supply voltage is 11000 V?
The standard three-phase distribution transformer in the UK is a delta/star connection with a rated primary line voltage of 11 kV, and a nominal secondary line voltage of 400 V, giving a secondary phase voltage of 230 V.So, the secondary provides a three-phase, four-wire, system comprising three line conductors and a neutral conductor. The line-to-line (line voltage) voltage is 400 V and the line-to-neutral (phase voltage) voltage is 230 V.There are not 'three types' of supply obtained from this arrangement.
Does line to ground voltage always half the value of line to line voltage?
Line to Ground voltage = line to line voltage / 1.73AnswerIt depends what configuration is being measured. In the case of the secondary of a split-phase distribution transformer used to supply residences in North America, the answer is yes. In the case of a star (wye) connected secondary distribution transformer used to supply residences in Europe, no: the line to ground voltage will be as described in the first answer.
Why is the secondary of three phase distribution transformer usually connected in Y?
The secondary of a three-phase distribution transformer is typically connected in a Y (wye) configuration to provide a neutral point, which allows for the safe distribution of single-phase loads alongside three-phase loads. This configuration also facilitates the use of lower voltage levels for residential and commercial applications, improves voltage regulation, and reduces line losses. Additionally, the Y connection helps in balancing the load across the three phases, enhancing system stability and efficiency.
How do you tell if you have delta or wye power?
In Europe, low-voltage three-phase distribution is by means of a four-wire system (three line conductors and a neutral) supplied from a wye-connected transformer secondary. In North America, low-voltage is supplied from a delta-connected transformer secondary, one phase of which is centre-tapped and earthed (grounded). The single-phase supply to residences is then supplied by that particular phase, giving 240 V line-to-line and 120 V line-to-neutral. You can tell if you have a delta power when the phase voltage is equal to the line voltage and that you have a star power when the phase voltage =root 3(THE LINE VOLTAGE).
Is there a basic difference between a three phase power transformer and a three phase distribution transformer?
The basic difference is the secondary voltages. On a distribution transformer the secondary voltage is very high. This is to overcome line loss for transmission of electricity over long distances. A three phase power transformer is used at the consumers three phase services end to manipulate voltages that consumers need to operate their equipment. The transformer that feeds your house is considered to be a single phase power transformer.

What is the function of transformer 33kv?
A '33-kV transformer' is a three-phase primary-distribution transformer, used in the UK's electricity system to step down the 33-kV primary-distribution voltage to the 11-kV secondary-distribution voltage -the lowest voltage used in the high-voltage distribution system. These transformers are categorised as 'power transformers', and are located in what are termed 'primary substations'.
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 kva rating of single phase transformer?
This is the rated output of the transformer, obtained by multiplying the rated secondary voltage by the rated secondary current. And it's 'kV.A', not 'kva'.

What are possible uses of a single phase 30VA transformer?
To continuously supply a load of up to 30-V.A at the rated secondary voltage of the transformer.
What is the mutual coupling in single phase transformer?
primary winding flux links with secondary winding produses voltage across the secondary winding
What is DY11 transformer?
A DY11 transformer is a three-phase transformer configuration where the high voltage winding is connected in a delta (Δ) configuration and the low voltage winding is connected in a star (Y) configuration. This configuration is commonly used in power distribution systems to step down high voltage to a lower voltage for industrial and commercial applications.
