echoed through the bay. The oil inside the tank rippled, but the steel casing held firm. The Assessment
Reactance Measurement: The variation in short-circuit reactance before and after the test must be within very tight limits (typically 1% to 2%), as a change in reactance indicates a change in the physical geometry of the windings. Conclusion
