| Characteristic | Value |
|---|---|
| Operation accuracy 1 | Depending on the frequency of the measured current and voltage: f = f n ±2 Hz |
| Power measurement accuracy ±3% of the set value or ±0.002 × S n Phase angle: ±2° |
|
| Start time 2, 3 | Typically 45 ms |
| Reset time | Typically 30 ms |
| Reset ratio | Typically 1.04 |
| Operate time accuracy | ±1.0% of the set value of ±20 ms |
| Suppression of harmonics | -50 dB at f = n × f n, where n = 2, 3, 4, 5,… |
1 Measurement mode = “Pos Seq” (default)
2 U = U n, f n = 50 Hz, results based on statistical distribution of 1000 measurements
3 Includes the delay of the signal output contact
