How do you connect a 230V lamp to a 415V supply with no neutral?

Theoretically, you could connect three identical lamps in star (wye) and connect this to the three line conductors. But as you asked how to connect a (single) 230-V lamp to the supply, then the answer is by using a step-down transformer.

Can you give 415v supply to 380v winded motor?
No. you cannot connect a 415 V to a 380 V motor. in case if you want to do that, you need to increase the number of turns in all the three phases of winding as per the turns calculation.
What are the application of core type transformer?
The main application for a core type transformer is to increase voltage from a standard 240v supply up to 415v instead of using a 3 phase supply.
What is the acceptable value of contact resistance in 415V air circuit breaker?
415v air circuit breaker acceptable value of 0.01 ohms and lessthan
What is the value of 3 phase voltage in India?
In India its 415V, 50Hz.
What is the UK 3 phase voltage?
The nominal voltage in the UK is 400/230 V. That is 400 V line-to-line (i.e. line voltage), and 230-V line-to-neutral (i.e. phase voltage). Allowable variation is +10% and -6%.
Can you convert 415v 3 phase to 230v single phase?
415V 3 phase is the line to line voltage. The line to neutral of this supply is 230V single phase. Therefore you use one of the phases and the neutral.
What is low voltage transmission?
In the supply industry it refers to circuits of below 1000 volts. Common voltages used are 120v, 208v, 230v, 240v, 277v, 400v, 415v, 480v.
What is the Single phase voltage in India?
The single phase voltage in India is 230v when we check with the phase and the nutral single line

Why always induction motor's terminal named as UVW?
The three coils are actually called UVW. They are called that because they are for the three phases of a 415v supply.
What is the purpose of a neutral conductor in 3 phase?
If you want to have a 3-phase service with a neutral then one way to get it is to connect the incoming three phases of a standard 3-phase service to a transformer whose secondary windings are connected in what is called a "star" (also known as a "Y" or "wye") configuration which has a neutral point at the center of the "star" or "Y".Then, to get a single-phase service, you can use just one phase and the neutral. This results in about half the voltage - actually it's 1 / 2./'3 (1 divided by the square root of three) - that you'd get across any two phases of the incoming 3-phase service.NoteA three phase service on its own does not have a neutral line. The voltage difference is measured between the phases. (No voltage can be measured between any of the phase lines and a neutral because there is no neutral line.)Any electrical equipment which uses a 3-phase service exactly as it is delivered by the power generator / utility - that is, without a neutral line - are connected in what is known as "delta" connection.
What is the Difference between 415v 3 phase motor with a 230v 3 phase supply?
IF YOUR MOTOR HAS 6 LEADS (IN THE TERMINAL BOX) OR 9 OR 12 LEADS THERE IS NO PROBLEM. IF IT IS A BRAND NEW MOTOR THE WINDING CONNECTION DIAGRAM IS NORMALLY INCLUDED IN THE NAMEPLATE OR INSIDE THE TERMNAL BOX - T1,T2,T3,T4,T5,T6 OR U,V,W,X,Y,Z MARKINGS. DUAL VOLTAGE APPLICATION IS A NORMAL OPTION FOR MOTORS. IN THIS CASE CONNECT IT IN WYE (SOME CALLED IT STAR) CONNECTION BY CONNECTING OR COMBINING T4,T5,T6 AS COMMON OR NEUTRAL THEN APPLY 230V 3 PHASE POWER SUPPLY AND CHECK DESIRED ROTATION OR ELSE JUST INTERCHANGE ANY TWO SUPPLY LINE TO CORRECT ROTATION.AnswerJudging from the values of voltage that you quote, you appear to be referring to the UK supply system. In that case, a three-phase supply has a line voltage of 415 V and a phase voltage of 240 V. So you can simply connect the machine's controller directly to the three line conductors. (These days, the nominal voltage for UK supply is now 400/230 V although, in practise, it is still 415/240 V).
Can you use a 415v motor in a 240 v socket?
No you can't use a 415v motor in a 240 v socket.
What is the acceptable value of contact resistance in 415V air circuit breaker?
415v air circuit breaker acceptable value of 0.01 ohms and lessthan
Can a 415v 50hz motor run on 380v 50hz?
no
If a 6.6KV Motor run at 415V then what happen to its current and RPM?
Current shall increase while you apply 415V for operating it and will decrease the rpm to a much low level.
