Your question should read, 'How much clearance is needed between LINES.... (not 'phases')?' The answer will depend on local authority regulations. The clearances in air tolerated by REC companies in the UK is 90 mm line to line and 127mm phase to earth. Even though there is a greater potential difference between line to line, the gap is less. I think it's to do with public safety if it flashes to earth.

What is the clearance for 480 Volt?
When dealing with a 3 phase power supply the safe clearance zone between each phase is usually within an arms reach, there are exceptions to this rule like a 3 phase socket or a distribution board.
What is clearence between phase to phase in 33 kv?
The clearance between 33-kV line (not 'phase'!) conductors depends on whether they are rigid (e.g. busbars) or can move (e.g. overhead lines); whether they are insulated or in air; etc.. So there are several 'clearance' distances. All are published on the internet -so you can do a search to find out for yourself.
What is the space between two single phase conductors?
Insulation.Can be air (as in overhead powerlines) or a non conducting material ( as in a power cord)AnswerPresumably, you are asking what the clearance is between two conductors? If so, then it depends on the voltage between them; the higher the voltage, the greater the clearance must be.
Earthing required for machine operating on 2phase?
Do you REALLY mean a 'two-phase' system? Two-phase systems are archaic, and haven't been used for many decades.
What is Electricity use difference between 3 phase and 1 phase?
A two-phase a.c. system is an archaic system, in which two phase voltages are generated 90 electrical degrees apart. It has nothing whatsoever to do with the US 'split phase' system that supplies North American homes. A two-phase system can be a four-wire system, or a three-wire system, and was useful because, unlike a single-phase system, it could create naturally rotating magnetic fields in induction motors. It has long been superseded by the three-phase system.
What is the clearance in air required for 150 kv bil.?
Phase to phase clearance should be around 11.5 inches.
What is the clearance for 480 Volt?
When dealing with a 3 phase power supply the safe clearance zone between each phase is usually within an arms reach, there are exceptions to this rule like a 3 phase socket or a distribution board.
How much harizontal and vertical line clearance is required in 33kv and 11kvphase to phase and phase to ground?
The minimum separation for a voltage of 34.5kV and conductor spans of 50 meters or less is 600 mm. The vertical clearance is 6.7 meters . For countries that never changed to the metric system 50 meters is about 150 feet and 600 mm is about 24 inches, 6.7 meters is about 22 feet. The minimum separation for a voltage of 15 kV and conductor spans of 50 meters or less is 400 mm. The vertical clearance is 6.1 meters.
Clearance between phase to earth?
for 415V phase to earth min clearance is 25mm pallavCommentYou cannot have a voltage between a 'phase' and earth. You should be asking the clearance between a 'line' and earth.

What is the Phase to phase clearance for 33KV sub station?
1.2 meter

Why is G zero for a phase change?
G is zero for a phase change because at equilibrium, the Gibbs free energy of the system remains constant, indicating a balance between the energy required to break intermolecular forces in the initial phase and the energy released when forming new intermolecular forces in the final phase.
What is the difference between energy investment phase and energy payoff phase?
The energy investment phase refers to the initial energy input required to start a process, such as plant growth or a workout. The energy payoff phase is when the system begins to produce a net gain in energy output, surpassing the initial investment.
Why required the vector group?
The vector group of a transformer is required to specify the phase shift between the primary and secondary windings. This information is crucial for operating multiple transformers in parallel and ensuring they are in phase with each other. The vector group helps maintain the proper voltage and current relationships between transformers in a power system, ensuring efficient and stable operation.
What is dffrence between single phase and three phase?
In a single-phase system, one tension is provided by 1 phase and the neutral wire, which is convenient for domestic electricity consumption. As for the 3-phase system, you have 2 voltages: *between any phase and the neutral conductor, you have the PHASE VOLTAGE (V) *between one phase and any other, you get the LINE VOLTAGE (U) ;which is greater than V. Relation between these voltages is: U = V x sqrt[3] The advantage of such a "polyphased" system is obvious, since the electric power is divided into the three phase, you get less Joule loss compared to a single-phase system with the same total power. That's why great consumers of electricity (such as factories) chose to be powered through three-phase.
HOW and Why there is 440v supply in three phase and 230v supply in single phase?
In a three-phase system, the voltage is measured between any two of the three phase conductors. The voltage between two phases in a 3-phase system is higher at 440v compared to a single-phase system where the voltage is measured between one phase and a neutral wire, resulting in 230v. The higher voltage in three-phase systems allows for more power to be transmitted efficiently over long distances.
