16 - Ekip Measuring Measurements
Presentation
These measurements are available in all the models of trip units of the Ekip TOUCH range supplied with Ekip
Measuring module or Ekip Measuring Pro.
The following is a list of the available measurements:
Measurements Description
Instantaneous voltages Real Time measurements of the voltages
Instantaneous power Real Time measurements of the active, reactive, apparent power
Trips List of the trips due to voltage, frequency, power
Maximum voltage History of the maximum voltages recorded with an interval that can be set
Minimum voltage History of the minimum voltages recorded with an interval that can be set
Maximum power History of the maximum active powers recorded with an interval that can be set
Average power History of the average active powers recorded with an interval that can be set
Power factor Real time measurement of the power factor
Instantaneous
frequency
Measurement of the line frequency
Energy counters Measurement of active, reactive, apparent energy
With the Ekip Measuring Pro module and Ekip Synchrocheck, a further set of measurements is activated:
Measurements Description
Synchrocheck
Measurements related to the function of synchronism between two
independent power supply systems
Power references
Displayed operating ranges and maximum values of power described in this chapter are given in absolute
value or in relation to:
• Pn for the total power (Sn = In * Un * √3).
• Pn for the phase power (Pn = In * Un / √3).
Instantaneous voltages
Description
Instantaneous voltages are measurements in real time of the line-to-line and phase voltages.
NOTE: the measurements of the phase voltages are available with four-pole or three-pole
circuit-breakers configured with external neutral.
Representations and access pages
Voltage measurements are available in different representations, accessible from the following pages:
• In the Histograms page there is a graphical representation in the form of a histogram of the line-to-line
voltages, and the measurement in Volts of the highest voltage.
• In the Measurements Synthesis page, accessible from the Histograms page, there is the measurement
in Volts of the highest line-to-line voltage.
• In the Measuring instruments page there is a graphical representation in the form of a voltmeter and
measurement in Volts of the highest line-to-line voltage.
• In the Measurements page there are measurements in Volts of all the line-to-line voltages and phase
voltages.
The measurements in Volts are available from a minimum value of 5 V to a maximum value of 1.25 Un.
NOTE:
• "..." is displayed, for voltage values lower than 5 V, "> 1.25 Un" is displayed for voltage values
greater than 1.25Un (example: with Un = 100 V, "> 125 V" is displayed).
• In the Histograms page, the graphical representation of the voltages relates to 1 Un, with a
maximum value of 1.25
