What is ment by KVAR and what are the advantage&dis-
advantages of KVAR

Answer Posted / pradeep

kvar is nothing but the reactive power which is injected by
the capacitor bank. this power is similar to the real power
which generated by the generating unit.

by using capacitor bank we reduce losses like transmission
loss etc.,

advantages:
1. easy to convert the 2-phase into 3-phase.
2. reduce the losses and increase the efficiency.
3. it ensure upto 200Mhz

disadvantages:
1. it will inject the more power when bank is not necessary.
2. expensive due to connecting the capacitor bank.

1. A 380 / 220 V r.m.s. 3-phase 4-wire circuit carries loads of 8 + j8.1 ohm; 4 + j4.1 ohm; and 2 +j2.1 ohmin the three phases respectively. The length of the circuit is 100 m, and the resistivity of the phase conductors is 0.0005 Ω/m. The neutral conductor is of the same size as the phase conductors. a) Select a reference angle 0for the first phase. Then write down the three phase voltages in both polar format and complex number format. b) Make appropriate assumptions, and take temperature effects on resistance is insignificant. Calculate the currents in the three phases. (Note: Determine conductor resistance, and apply Kirchhoff’s Voltage Law) Based on the result, suggest a main switch rating for the circuit. c) Show your preferred direction of neutral current in a diagram, and then determine its value. (Note: Apply superposition principle, and Kirchhoff’s Current Law) Use its magnitude to show that in this circuit, the unbalanced load may increase the voltage drop in some of the phases. (Note: Also observe the common volt drip in neutral) State your assumptions, if there are any. d) Suddenly the neutral wire of the circuit is broken. Estimate the new currents in the first phase, i.e. Phase L1. State your assumptions, if there are any.
