15- a) Explain two wattmeter method for three phase power measurement. Also, how it is different from one wattmeter and three wattmeter method,
- b) AS kVA, 200/1000 V, 50 Hz, single phase transformer gave the following test results: OC test: 200V, 1.2 A, 90 W SC test: 50 V, SA, 110 W : i. Calculate the parameters of the equivalent circuit referred to LV side.
- ii) Calculate the output secondary voltage when delivering 3 kW at 0.8 power factor lagging, the input voltage being 200 V. Find also the percentage voltage regulation.
A worked answer is on its wayMeanwhile, read the Basic Electrical Engineering notes for this topic.
