The single phase induction motor starts with two phases(Using capacitor). Why can't the three phase induction motor starts with two phase?
Latest Answer: For the starting of a single phase motor we need two different fields and the resultant of both the fields works as the operating field revolving the motor
in the direction of strong field (for more refer double field revolving theory).
For the starting ...
What is the importance of 'Q Point' in transistor's load line analysis?
How short circuit calculation done at secondary side of transformer?
Latest Answer: The low voltage side is short circuited with measuring instruments(Ammeter and wattmeter) in HV side. Now the input voltage is increased to read rated current in LV side. Corresponding HV side reading is noted ...
How can we make use of excessive power efficiently?
What is the difference between INVERTER and UPS?
Latest Answer: From UPS we can get regulated power supply (Sine wave). But in Inverter we get filtered square wave that means we can't get sin wave from inverter. ...
Suppose the electricity board gives 11 kw, but the machine requires only 8 kw in such case how can we save the excess power?
Latest Answer: Even the supply is capable of deliver more power than the required power, the machine will take howmuch power that needed. ...
Why many people do not connect the APFC/Capacitors in DC circuit?
Latest Answer: APFC means Automatic Power Factor Controller. Power Factor is applicable only in an AC Supply, DC is one of direct current, there is no Power Factor in DC Supply. ...
Why many people not connect the APFC/Capacitors in DG circuit?
Latest Answer: When normal supply is 'On' that time APFC will be on, At that time it will consume current, for correcting P.F, in case of D.G will not run continously so avoid over load on D.G APFC panel not connected. ...
Does lightening contain voltage or current, Explain.
Latest Answer: An electrical discharge between cloud and earth, between the charge centre of the same cloud is known as LIGHTENING,A direct or indirect lightening stroke on a transmission line produces steep-fronted voltage wave on line, the voltage of this wave may ...
