Example 2.2 || Equivalent Circuit of a Transformer || (English)(Chapman)
00:00 - Intro
00:10 - Losses in Transformer
01:05 - The equivalent circuit
03:40 - Equivalent circuit reflected to pri and secy side
04:30 - Simple equivalent circuit
05:20 - Determining component values by open circuit test
07:00 - Determining component values by short circuit test
08:00 - Example 2.2
A 15-kVA, 23001230-V transformer is to be tested to determine its
excitation branch components, its series impedances, and its voltage regulation. The following test data have been taken from the primary side of the transformer:
Open-ciITuit tcsl
Voc = 2300 V
loc = 0.21 A
Poc = SOW
Short- circuillesl
Vsc = 47V
Isc = 6.0A
Psc = I60W
The data have been taken by using the connections shown in Figures 2- 19 and 2- 20.
(a) Find the equivalent circuit of this transformer referred to the high-voltage side.
(b) Find the equivalent circuit of this transformer referred to the low-voltage side.
(c) Calculate the full-load voltage regulation at O.S lagging power factor, 1.0 power
factor, and at O.Sleading power factor.
(d) Plot the voltage regulation as load is increased from no load to full load at power
factors of O.S lagging, 1.0, and O.S leading.
(e) What is the efficiency of the transformer at full load with a power factor of O.S
lagging?
