Setup of Monitor Limits, a survey of adjustments.
Limits | Adjustments |
|
|
Voltage | 2 Probability percentages (100 % and adjustable): |
| each with adjustable upper and lower limit. |
Harmonics | For each harmonic 2 Probability percentages (100 |
| % and adjustable): each with adjustable upper limit. |
Flicker | Weighing curve (lamp type). 2 Probability |
| percentages (100 % and adjustable): adjustable |
| percentage with adjustable upper limit. |
Dips (*) | Reference voltage (Nominal or Sliding). Threshold, |
| hysteresis, allowed number of dips/week. |
Swells (*) | Reference voltage (Nominal or Sliding). Threshold, |
| hysteresis, allowed number of swells/week. |
Interruptions (*) | Threshold, hysteresis, allowed number of |
| interruptions/week. Reference voltage is Nominal. |
Rapid Voltage Changes (*) | Voltage tolerance, Steady time, Minimum step, |
| Minimum rate (V/s), allowed number of |
| events/week. |
Unbalance | For each harmonic 2 Probability percentages (100 |
| % and adjustable): adjustable percentage with |
| adjustable upper limit. |
Frequency | 2 Probability percentages (100 % and adjustable): |
| each with adjustable upper and lower limit. |
Mains Signaling | 2 Adjustable frequencies. For each frequency 2 |
| probability percentages (100 % and adjustable): |
| adjustable upper limits (**). |
(*): setups that are also valid for measuring mode Dips & Swells. Events per week is used for Monitor only.
(**): when changing frequency, limits automatically follow the EN50160 ‘Meisterkurve’, but can also be set manually. The ‘Meisterkurve’ is shown in the figure below.
