how the CT and PT is connected in the circuit during testing of transformer explain with diagram
how meger function
it is in our knowledge tht right plug of supply of residential suppy system is phase n other is neutral...howevr the battery charger of mobile works in both ways...i mean it is not restricted in only one direction.ny of the holder of charger can hav phase .so y is it not lik tht phase of supply must b connected 2 phase of charger...?

To prove the capacity of a 10MVA transforemr with 6.5% impedance by a short circuit test how much power is needed to inject an impedance voltage if we have to arrive for its rated current?
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 0for 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.
