What will happen if induction motor is in star-star connected?
If a motor is connected in a star configuration it will operate at a slower speed. This is the working process that a star delta starter operates on. At first through the starter the motor starts in the star connection. When the motor gets up to its highest speed in that connection it times a timer out , the star starter drops out and the delta starter pulls in and then connects the motor in the delta connection. This allows more voltage to be applied to the motor and it then speeds up to its nameplate rated RPM.
How can a dlta connected motor be converted in star?
If the motor terminal has six terminals in the terminal box, then it can be connected either in delta or star. If there are only 3 terminal wires then the motor can not be connected in star.(it means that the motor is designed to be connected in delta only)
What is an electrical star delta configuration?
A star configuration of the windings in a 3-phase transformer or motor is where one end of each winding is connected to form a star or 'Y' pattern and the other ends are each connected to one of the three separate lines of the incoming 3-phase electrical service.A delta configuration is when each phase winding of a three phase transformer or motor is connected to its two adjacent phase windings to form an arrangement that looks like the Greek letter delta - or triangle - and then each point of the triangle is connected to to one of the three separate lines of the incoming 3-phase electrical service.To be able to wire a 3-phase transformer or motor either in star or delta, all 6 ends of the three sets of coils, called "windings", have to be exposed with suitable connection terminals.The windings are often labelled A1, A2, A3 and B1, B2, B3, where "1", "2" and "3" denote the separate phase windings and "A" and "B" denote the beginning and end of each winding.Another way of describing it is to say that the separate windings can be labelled:Winding 1: A1 B1. Winding 2: A2 B2, Winding 3: A3 B3.In star configuration either all the A's or all the B's are connected together and the 3-phase supply (consisting of three separate "phase lines" labelled L1, L2, L3) is connected to the remaining three connectors. For example, if you connect B1 to B2 and B2 to B3 to form the center of the "star" then you must connect supply L1 to A1; supply L2 to A2 and supply L3 to A3.In delta configuration, connect B1 to A2, B2 to A3, B3 to A1. (If you draw that out as a schematic diagram, it will be a triangle.) Then connect supply L1 to A1; supply L2 to A2 and supply L3 to A3. (Exactly the same as the supply lines were connected before, for the star configuration.)For more information see the answers to the Related Questions shown below.
What configuration was the first successful prototype transistor at Bell Labs connected in?
Common base connection.
Why do you need power stations and generators?
To provide electricity, which we all use. It is much more efficient to have large central power plants connected to a high voltage grid, than to have many small generators on a local scale.
What is the change over time from star to dealta in the start up of an electrical motoR?
The change from star to delta in the startup of an electrical motor involves switching the motor windings from a configuration where they are connected in a star pattern to a configuration where they are connected in a delta pattern. This change helps the motor to transition from starting with reduced current and higher torque (star) to operating at full speed and power (delta). It is a common method used to control the motor's performance characteristics during startup.

Generators were supplied and connected to power lines.

What are the At-At's in star wars?
they where used on hoth to destroy the generators
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.
Can two generators be connected to increase their output?
A: only if both are perfectly matched in their output
How is a star connected to the sun?
The Sun is a star.
Are honeywell generators energy star approved?
Honeywell generators are not energy star approved. This is because a generator is usually a source of backup power, or sole power if in a very rural area. They use a lot of energy and therefore are not energy star approved.
I have cisco router 2801 connected to mpls using serial port ethernet port connected to LAN with NATing enable what will be the sample configuration?
MPLS is pretty complex, and the configuration will depend entirely on the device to which it's connected. Presumably, that's your ISP's router on the other end. They should tell you what configuration you need to use.

Which kind of energy is produced by generators at a dam?
Generators at a dam produce hydroelectric energy by converting the potential energy of stored water in the dam into electrical energy through the rotation of turbines connected to the generators. This renewable energy source is clean and sustainable.
What is the equivalent resistance of three resistor with 3 ohms connected in star?
There is no 'equivalent resistance' for three resistors connected in star.
