The maximum power output of the transformer is measured in VA or KVA, (volt-amps) or thousand (volt-amps). That will will marked or stamped on the transformer. If you want to measure the amount of power being used by the Xformer, measure the Line side current in amps with an amprobe and multiply by the line voltage to it. The result in watts is the power consumption.

What is a single phase variac?
It is a variable autotransformer, a transformer with a sliding contact on the winding connected to a control knob, that allows the output voltage to be varied.
Can delta connection be used on 3 phase 4 wire system?
A delta connected appliance can be connected to a 3-phase system by leaving the neutral unconnected. The appliance must be properly earthed.
Theory for brake test on three phase induction motor?

What is the formula use for calculation voltage and current in star and delta?
Balanced Star (Wye) Connected Systems:Line Voltage = 1.732 x Phase VoltageLine Current = Phase CurrentBalanced Delta Connected Systems:Line Voltage = Phase VoltageLine Current = 1.732 x Phase Current
What is the difference between a Delta-connected and a Y-connected transformer?
With three windings, you have six terminals. Call them A1, A2, B1, B2, C1, and C2, representing phase A, B, and C. In the delta configuration, A1 is connected to C2, C1 is connected to B2, and B1 is connected to A2. Power is from phase to phase - A1C2, C1B2, and B1A2. In the wye configuration, A2, B2, and C2 are connected together, and are usually connected to neutral. Power is from phase to neutral - A1, B1, and C1.
When a circuit is described as a three-phase delta-connected 240 v circuit its categorized by?
circuit characteristics.
What is single phase autotransformer?
An autotransformer is a transformer with at least two windings where a part of one winding (the common winding) is shared between both primary and secondary outputs.
How do you get phase shift in Hartley oscillator?
basicaly the two inductors work as an autotransformer,providing a phase shift of 180 degree
Why is there no neutral point for delta?
There is no neutral in a delta connection, because that is the definition of delta, a power configuration where current flows from phase hot to phase hot. The loads are A-B, B-C, and C-A. Contrast this with star, where there is a neutral, and the loads are A-N, B-N, and C-N.
What is the equation of stardelta?
The voltage of a winding that is connected in star is 1 over the square root of three, 1 / 1.732, or 0.5774, of the voltage if that winding were connected in delta. This results in a star power of 1/3, or 0.3333, of the delta power.Similarly, if you know the winding current in delta, you can calculate the star current by multiplying by 1.732.This all presumes that the neutral point of the star is symmetrically centered in the middle of the phase triangle.
Are contactor points and bimetallic strip connected to the star delta starter of 3 phase induction motor?
yes
