Final answer:
The calculation of the single-phase equivalent circuit for a three-phase induction motor involves complex analysis of no-load and blocked-rotor test data, combined with the known stator resistance. Without a detailed process and additional information, the parameters cannot be accurately determined.
Step-by-step explanation:
To calculate the parameters of the single-phase equivalent circuit for a three-phase, four-pole 60 Hz induction motor rated at 100 hp with line-to-line voltage of 2100 V, we use the data from the no-load and blocked-rotor tests, along with the stator resistance per phase. However, this requires a complex process that includes calculating the magnetizing reactance and core loss resistance from the no-load test and the rotor resistance and reactance from the blocked-rotor test. This involves solving a set of equations derived from the test results which are beyond the scope of response here without a detailed understanding of the tests and measurements provided.
The stator resistance given is 1.4 Ohms per phase. Considering this information, one would proceed by forming an equivalent circuit model for the motor, typically composed of known resistances and reactances that represent different parts of the motor such as stator winding, magnetizing branch, and rotor elements. However, with the provided data alone, we cannot reliably calculate all aspects of the equivalent circuit parameters. Detailed engineering analysis and calculations would be required for a definitive answer.
