Table 6 Limits of voltage distortion according to IEEE standard 519–201441
From: Condition monitoring and fault diagnosis of power transformer based on non-invasive measurement
Bus voltage V at PCC | Individual harmonics (%) | Total harmonic distortion THD (%) |
|---|---|---|
\(V\le 1.0 KV\) | 5.0 | 8.0 |
\(1.0 KV<V\le 69 KV\) | 3.0 | 5.5 |
\(69 KV<V\le 161 KV\) | 1.5 | 2.5 |
\(V>161 KV\) | 1.0 | 1.5 |
