Question 1 of 5

What is the primary purpose of an open-circuit test on a transformer?

The open-circuit test isolates core losses by leaving the secondary open.
Question 2 of 5

In a short-circuit test, which side of the transformer is typically short-circuited?

The low voltage side is short circuited to avoid high currents on the HV side when energized.
Question 3 of 5

What parameters are primarily determined from a short-circuit test?

Short circuit test helps determine parameters related to the windings, mainly copper losses.
Question 4 of 5

Which instrument is essential for measuring the input voltage during both open-circuit and short-circuit tests?

A voltmeter is needed to measure the applied voltage in both tests for analysis.
Question 5 of 5

Before conducting any tests on a transformer, what is the most crucial safety precaution?

Safety comes first. Disconnecting from power ensures safe working conditions.
