17 - Hi-Touch measurements
Presentation
Hi-Touch measurements are available for Ekip Hi-Touch and Ekip G Hi-Touch trip units.
IMPORTANT: the measurements are available with trip units equipped with auxiliary
power supply.
The following is a list of the available measurements:
Measurements Description
Waveforms Display of the waveforms of the voltage and current signals and current
Harmonics Display of the harmonic component of the voltage and current signals
Network Analyzer Statistical analysis of voltages and currents
Waveforms
Path
Main page - Menu - Measurement - Network Analyzer - Waveforms
Description
The selection of one of the listed quantities opens the representation of the waveform of the selected quantity
acquired at the moment of selection.
The quantities with which the waveform can be displayed are:
• Phase currents L1, L2, L3, Of.
• Line-to-line voltages V12, V23, V31.
NOTE:
• The Ne phase current is available with four-pole or three-pole circuit-breakers with external
neutral.
• For details on the pages, see the chapter “Menu Page and menus”, and the paragraph
“Measurements Menu”, on page 51.
Harmonics
Path
Main page - Menu - Measurement - Network Analyzer - Waveforms
Description
In the above mentioned page, the Harmonics key opens a representation in the form of a histogram of the
measurements of the harmonics constituting the waveform, and related to the frequency set in the menu
Settings.
In order to display the harmonics, you need to enable the calculation of the harmonics through the parameter
Harmonic, available in the menu Measurements.
NOTE: For details on the pages, see the chapter “Menu Page and menus”, and the paragraph
“Measurements Menu”, on page 51.
Network Analyzer
Path
Main page - Menu - Measurements - Network Analyzer (for the measurements and the counters)
Main page - Menu - Settings - Network Analyzer (for the control parameters)
Description
The Network Analyzer function allows you to set voltage and current controls over a long period, in order to
analyze your system.
To this purpose, voltages and currents are monitored, so as to find:
• Voltage sequences.
• Short voltage sags or interruptions.
• Short voltage increases.
• Slow voltage sags.
• Slow voltage increases.
• Unbalances between the voltages.
• Harmonic distortion of voltages and currents.
