|
| Event List | | Dips, swells and interruptions are detected and stored in the event list. Also any trigger which fires generates an event added to this list. | | The Event list shows the exact time when the event occurred as well as the duration and magnitude. Sorting by several attributes of these events is possible to select one for further root cause analysis. | | RMS values, transients and fast transients can be stored if a trigger fires. |
|
| Continuous Recording | | Fluke 1760 records rms values together with corresponding minimum and maximum values for: | | • Voltage | | • Current | | • Power P, Q, S | | • Power Factor | | • kWh | | • Flicker | | • Unbalance | | • Frequency | | • Harmonics/Interharmonics | | continuously with the following time aggregations: | | Day | | 10 min | | Free Interval, e.g.: 15 min, 2h |

| Input filter | | Each channel is equipped with a passive low-pass filter, an anti-aliasing filter and a 16-bit A/D converter. All channels are sampled synchronously with a common quartz-controlled clock pulse. | | The filters protect against voltage transients and limit the signal rise rate, reduce high frequency components and especially the noise voltage above half the sampling rate of the A/D converter by 80 dB, thus achieving very small measuring errors in an exceptionally large amplitude range. This is also valid under extreme operating conditions like transient voltages at the output of converters. |
