 Related Questions Latest Answer : HVDC- High Voltage DC Transmission system ,from the name itself we can say that its a dc transmission system and a dc transmission has two conductors one phase and other neutral. phase conductor is used to transmitt the current from sending end to receiving ... Read Answers (4) | Asked by : Anandkumar Latest Answer : Reson 1 is the way power is generated. Due to the construction of generators, the default wave form is sinusoidal. Secondly, the frequency of sine wave is a single definite value while other wave forms are formed due to harmonics along with the fundamental ... Latest Answer : Control Panels literally help in controlling power supplied. It helps in protection and cntrols the various CBs and other protection Equipments. It hac Current relays etc to sense the current.I also helps to pinpoint the location of faults in feeders. ... Read Answers (1) | Asked by : sa Why are we employing star type transformer at transmission end and delta type transformer at receiving end? Latest Answer : Delta star transformer used in distribution purpose because of earthfault on star side do no reflect on delta side of winding. Zero phase current is eleminated in delta side of transformer and another reason for delta winding line current = 1.732 * Phase ... What is Transmission Line? How it is used? Give examples. Latest Answer : Line which is used to trasmit the high voltage or high power is called transmission line, high voltage E.g. 220kv, 132kv, 66kv etc. all this voltage are of transmission voltage range. Example of transmission line is : D.C line of +/- 800kv ... What is the fuction of electrical current transducer, voltage transducer in control panel? Latest Answer : Tranducers are used to convert Electrcal Quantities to standard signal of 4-20mA or 0-10 V etc. The main advantage of using them that possibility of opening of CT when changing ammeters , damage(burnt) of ammeter etc. It is also used to display ... Why is alternating current used for transmission? Latest Answer : To reduce I-squared x R loss, transmission is done at voltages much higher than what is usable by consumers. Transformers can easily raise AC voltage for transmission and then lower it for consumption. The same cannot be done for DC power. ... Give brief detail on PID Control. Latest Answer : A controller is a device employed to obtain a stable output. There are many
controllers of that PID controller is the most widely used. A
proportional–integral–derivative controller (PID controller) is a generic
control loop feedback mechanism ... Why neutral point is not required in high transmission line? Latest Answer : It will be simply wastage of money to use a neutral wire in transmission line, however technically it will not give any adverse effect, but as the line is not directly fed to a single phase consumer / any consumer then it will be wastage of money to carry ... How we can step-up or step-down the DC voltage directly? Latest Answer : We can do this with the help of a suitable chopper. Both types are available either step up or step down. ...
