Why are transformers used to increase the voltage before transmission?
Using a higher voltage reduces power losses during transmission.
How often is power turned off during a cycle of ac voltage?
Twice.
What will happen to the transformer if double the rated voltage is applied to the winding during the open circuit test?
no voltage will be induced on the secondary side of the motor as the windings will become saturated.
What is the meaning of rated power frequency withstand voltage?
The r.m.s of sinusoidal power frequency voltage that the equipment can withstand during tests under specified conditions and for a specified time
What electrical characteristics remains the same during normal residential electrical use?
The voltage level
Why the alternator voltage drop during starting on no load and few secon later voltage pick up automatically?
when a high power equipment the draws more current initially then comes down will show the affect you questioned. just like motors heaters blowers. intially the put a huge demand for power on source. it generally happens when the source is half loaded and a 5 % of its capacity load is added
Why on a 1994 3.4L Camaro would your voltage go down during idle and decel after replacing both your battery and alternator?
I meant to say "even after" replacing those parts.
How to control Battery voltage?
In an automobile the battery voltage is controlled by a regulator unit wired along with the battery. It limits voltage and protects lamps as well as electronic devices from higher voltages obtained when a fresh battery is charged to its full capacity. A battery is usually rated at 12 volts but when charged it may have a voltage of 12.6 to 13.2V. A regulator is also needed during charging by the alternator since at higher RPMs the alternator may deliver voltages in excess of 17 to 18 volts.
What are the causes of reverse power during parallel operation?
In very simple terms, if the voltage output of the device being paralleled is lower than that of the device already on line, then energy will flow back to the device being paralleled. In practise, it can be far rather more complicated than that: for example an alternator connected to the grid can have the same voltage as the grid, but if insufficient torque is applied to its rotor, then energy can flow back to the alternator, causing it to 'motor'.
What is restriking voltage?
Restriking voltage is transient voltage. During the arcing time, at current zero, the voltage that shows up across the contacts is the restriking voltage.
How do you know when to replace the alternator?
You need to get it tested. Auto Zone, Checker Auto, Kragen Auto or any of the local consumer auto parts distributors will check it for free. Call around if you have any questions. In general, if you want to run a primitive test yourself you can use a volt meter. Test the voltage before starting the engine, it should be around 12 volts, maybe a little lower if the battery isn't fully charged. Then start the engine. With the engine running and about 1000 RPM you should have 13.5 Volts at the battery. the easiest is to go to the local parts store most can check them right on the car. compare engine off voltage to engine running voltage. If it does not go up during engine running it is probably bad. Hey Lakisha==Take it to Auto Zone and they can check it out for free. Goodluck Joe If it is makeing a noise or is not putting out at least 13.5 volts it is bad. Take the car or the alternator to an Auto Parts store and have them load test the alternator to be sure. Just disconnect one of the battery post.If engine dies your running on battery.Are have an auto store check it for free they test load it. E.C.H Depending on the vehicle< it could range from the alternator gauge not registering a charge to an alternator light on the instrument cluster staying on. The easiest way to check this is to get a voltage meter and run it across the two terminals on the battery with the engine running. If you get a charge of 13.8 +/- 1 volt then it is charging if below with the engine running then the alternator is done. when the car is started disconect your battery and turn on your lights. if they are dim or dont come on your altinator is bad. Use a volt meter and measure the voltage on the battery with car NOT running. It should read 12 volt. Turn on the engine and measure the voltage on the battery again. If the alternator is good, the voltage should be 13+ or 14+ volts. If the alternator is bad, the voltage would be the same or less than 12 volt. If your battery is bad, the voltage would be less than 12 volt. You can also bring your car to an auto parts store and they will check it for you for free. have it tested,loss of electrical power is usually battery or alternator if happens slowly Disconnect the battery cable and see if your engine keeps runing. If the engine stops running your alternator isn't putting out any electrical power to your engine. Replace your battery cable and go have your alternator tested. If your alternator is good then start looking for a short somewhere. Sometimes the bearing inside the alternator will begin to make noise, not always. You can started the car, turn on the headlights, and then other accessories to see if the headlights dim when they are turned on. Alost of places like Autozone, Checker, and NAPA can bench test the alternator for you. Does your battery go dead when you drive for any length of time with the headlights on. If so there is a pretty good chance that your alternator is bad especially if the voltage regulator in internal (inside the alternator)
Why is a generator of a car is called an alternator?
Generators were used in vehicles up to the mid 1960's. They used dc voltage and were slow to replenish batteries. You had to drive approx. 7 miles at 30 mph or faster just to recharge battery to level prior to starting vehicle. Alternators replaced generators in the late 1960's. Alternator use ac voltage to recharge battery and will charge battery at vehicle idle. Much faster and more efficient than the generator. It is not unusual for an alternator to last the life of a vehicle where a generator would require a rebuild or replacement during the life of vehicle.
What is the climate during an ice age?
Suddenly very cold.
What injuries occur suddenly during an activities?
Acute Injuries A+.
What does to shoot up suddenly means?
The answer to "to shoot up suddenly" is to Sky-Rocket, Sprout. It is a Growth spurt that children have during Puberty.
What is an arc voltage in a circuit breaker?
ARC VOLTAGE is the voltage that appears across the contacts of circuit breaker during the arcing period, during which the current flow is maintained in the form of an arc. The arc voltage value is low except for the point at which the current reaches zero when the arc voltage rises rapidly to a peak value.
Why do I smile automatically during meditation?
Maybe it helps you relax a little and feel better, so you are automatically in a better mood.
