Question

Draw open circuit test diagram of transformer ? No goole plzzz​

Answer 1

Answer:

Here is a diagram of open circuit transformer.

Answer 2

open open circuit test

• this test is conducted to find shunt branch parameter and turns ratio .
• As shunt branch parameters from nonlinear circuit this test suite be conducted at rated voltage and at the rated frequency only.
• sant branch can be moved to earth primary side provided

1. component wattmeter reading representing primary compare to rated current.
2. component of voltmeter reading representing primary leakage impedance drop due to no load current is negligible compared to rated supply voltage.
