What happens to voltage when a single line opens on a three phase delta transmission system?
When a single line opens in a three-phase delta transmission system, the voltage in the remaining lines can increase due to the loss of the return path for the current. This phenomenon can lead to an unbalanced voltage condition, potentially causing overvoltage on the remaining phases. Additionally, the system may experience increased current on the other two lines, which can result in overheating and damage to equipment if not properly managed. Protective devices are typically employed to detect such faults and isolate the affected section of the system to maintain stability and safety.

What is service mains in power transmission system?
A 'service mains' is not associated with an electricity 'transmission' system, but with a low-voltage 'distribution' system. The service mains is the name given to the cable that connects a building to the low-voltage mains supply.
What happens if reactive power enters the system?
Reactive power entering the system will increase the system voltage.
What is the function of the oscillator in a cw transmitter?
It is the engine of the transmission system. It determines the frequency of where the CW transmission happens. CW transmission is the most efficient form of transmission. The majoity of power in this system is used for actual transmission and not for modulating a signal.
How does changing the voltage increase the efficiency of power transmission?
Changing the voltage during power transmission increases efficiency by reducing current flow for the same power level, which minimizes energy losses due to resistance in the transmission lines. Higher voltage allows for lower current, resulting in reduced I²R losses (where I is current and R is resistance). This means that less energy is wasted as heat, improving the overall efficiency of the power transmission system. Additionally, efficient voltage levels can enable longer transmission distances with less energy loss.
How do you calculate 440v phase?
Let's get the terminology correct. A 'phase voltage' is measured across a phase, whereas a line voltage is measured between two lines. So there is no such thing as a 'phase to phase' voltage -it's a line to line voltage (hence the term 'line voltage').

Is transmission voltage a phase to phase voltage or a phase to ground voltage?
Phase to Phase voltageCorrection to the above answer:There is no such thing as a 'phase-to-phase' or 'phase-to-ground' voltage. The correct terms are 'line-to-line' (or 'line voltage') and 'line-to-ground' (or 'phase voltage'). Transmission-line voltages are line-to-line (or 'line') voltages.
Size of wire need for 3 KW turbine for transmission?
To answer this question the voltage of the system is needed.
Three phase voltage in india?
It is 230V single phase and 440V in 3 phase system at 50 Hz.AnswerIf the single-phase voltage is 230 V, then the three-phase voltage must be 400 V, not 440 V. The line voltage is 1.732 times the phase voltage.

Can two power systems having different voltages be synchronised?
yes. it is happen only for HVDC transmission .. but we can't set different voltage at A.C transmission system...
Line voltage is understood to be any voltage?
The Line normally refers to the live wire in a single-phase system and the three live wire of a 3-phase system. In a 3-phase system the line voltage is usually quoted as the nominal voltage, and that is the voltage between any two of the live wires. The voltage between one of the lines and neutral is 1/sqrt(3) times less.

What happens to a 220v stereo when connected to 110v?
Stereo can't work unless sufficient voltage , same will be connected to higher input voltage your system will be damaged.
What is meant by three phase?
Three phase power is a method of electric power transmission using three wires. Three phase power systems may have a neutral wire that allows the system to use a higher voltage while still allowing lower voltage single phase appliances. In high voltage distributions, it is not common to have a neutral wire, as the loads can simply be connected between phases.
