WHAT IS LINE(VOLTAGE,CURRENT) AND PHASE(VOLTAGE AND CURRENT)

Line and Phase:

We all always have confusion between line and phase voltages....so now get some clarity here....
The issue of these line and phase voltages come into account only in case of 3-phase networks...that is either Star or Delta
Consider the above star connection.
Line Current:The current passing through the line that is IR,IB,IY are known as Line Currents.
Line Voltage:The voltage across two lines of a star connection that is VRY,VBY,VBR are Line Voltages.
Phase Current:The current passing through the Impedance that is IRN,IBN,IYN are Phase currents.
Phase Voltages:The voltage across the impedance that is VRN,VBN,VYN are known as Phase Voltages.
All these parameters are the same in case of Delta Connection also

SWITCHING TRANSIENTS IN TRANSFORMER

Switching Transients: The word Transients is always very Scary for me but not any more hahaaa...........what about you???? Well coming to the point...why do these Switching Transients occur in a Transformer. When the switch is closed when the voltage is maximum...then the flux required by the core is zero and the available flux in the core is also zero and hence NORMAL OPERATION is sufficient When the switch is closed when the voltage is crossing zero...then the flux required by the core is maximum but here the avaliable flux in the core is zero and hence TRANSIENT OPERATION is required Here when the Transient operation takes place then the flux doubles gradually and this is known as Doubling Effect of Transformer.This Doubling Effect causes magnetic in rush current and Damage in the insulation. Using Secondary Harmonic Restraining Coil can reduce all these Drawbacks.

TRANSMISSION LINES

Transmission lines The Transmission lines are basically Electrical Circuits having distributed constants such as Resistance,Inductance and Capacitance.These contants are uniformly distributed along the length of the line and there concentration at any particular point is not possible Basically these Transmission lines are Classified based on two cases, CASE 1: BASED ON LENGTH:- The Tranmission lines are classified into three types here 1.Short Transmission Lines:When the length of the Tranmission line is below 60 km then they are considered to be under STL 2.Medium Transmission Lines:When the length of the Transmission line is 80-160 km then they are said to be MTL. 3.Long Transmission  Lines: When the length of the Transmission line is above 160 km then they are said to be LTL. CASE 2: BASED ON OPERATING VOLTAGE:- Here the Transmission lines are classified into five types 1.Low Voltage:When the operating voltage is upto 1KV. 2.High Voltage:When the operat...
