voltage is not adjustable and is always L-N.
• In the 3-conductor network (e.g. mean voltage) the relevant voltage relates to a calculated star point.
4.3.5.6 Events
• An event occurs if threshold values set for the current and the voltage are violated.
• An event has a mean value, a minimum or maximum value, a start time and an end time.
• The ecoExplorer go event browser can display recorded events.
• Threshold values are set per measurement channel (L1...L4) for excess voltage, undervoltage and over-
current as a percentage of the nominal values.
• Threshold values can be switched off by switching the Manual/Off button to Off.
4.3.5.7 Event recording
• Effective values recorded in the Energy Analyser D550 describe the trend of full wave effective values.
• Effective value recording can be started by an event or by a Jasic program.
• Various recording modes can be selected to record effective values triggered by an event.
- Only the value in which the event was found.
- Only voltage and current in the phase in which the event was found.
- All of the inputs of the value in which the event was found.
- All of the values in all the inputs
• The length of the effective value record is determined by the number of full wave effective values up to
the beginning of the event (pre-run) and by the number of full wave effective values after the beginning of
the event (after-run).

4.3.5.8 Transients
• Transients are fast voltage changes.
• TheEnergyAnalyserD550recognisestransientsiftheyarelongerthan50μs,althoughitonlymonitors
the four voltage measurement inputs.
• There are two independent criteria by which transients are recognised.
- Absolute: If a sampled value exceeds the set threshold, a transient is recognised.
- Available settings:
- Off - transient monitoring has been switched off
- Automatic - the threshold value is calculated automatically and comes to 110 % of the current
200 ms effective value.
