____are long-term (hours-long) voltage sags caused by system overload.

A term brown out means it is an intentional or unintentional drop in voltage in an electrical power supply system.
Brown outs are long-term (hours-long) voltage sags caused by system overload.
Deviations from the regular sinusoidal wave, both on the utility side and on the customer side, result in poor power quality.

In transformer, a Sweep Frequency Response Analysis (SFRA) test will help detect ____

Frequency response analysis is the technique whereby a sinusoidal test signal is used to measure points on the frequency response of a transfer function or impedance function.
Sweep Frequency Response Analysis (SFRA) testing provides insight into the mechanical and electrical integrity of transformers.

Main Purpose of SFRA Test:
Transformer Core displacement
Winding displacement for both rotor and transformer
Broken or loosen clamp connections
Inter turn short circuit
Internal short circuit
Winding to Core Earth fault
Winding Open circuit condition
