How to measure harmonics during relay protection verification

Troubleshooting a power system for a suspected harmonics problem must include voltage and current measurements made with true RMS (root-means-square) digital meters. By using such a meter, you can accurately determine the voltage and current amplitudes in the presence of. For relay protection engineers, one of the pivotal challenges is managing harmonics—distortions that can severely affect power equipment, disrupt operations, and reduce system longevity. Since the basic function of a protection relay is to correctly function under abnormal. If you want to measure 2, 3 or 5 harmonics it's very easy. I found it more useful because usually we deal with relay settings in percentages. These relays operate based on Kirchhoff's current law by comparing the currents entering and leaving a protected zone.
