— Ekip Touch/Hi-Touch Measurement functions and data
Currents All the Ekip Touch/Hi-Touch trip units measure the RMS value of the instantaneous currents of the three phases and the neutral. There are two differ- ent levels of accuracy depending on the version (0.5% and 1%). In addition, also the minimum and maximum values recorded within an adjustable time interval are available. Voltage Instantaneous phase-to-phase and phase-to-neu- tral voltages can be measured. They are available at a 0.5% level of accuracy. In addition, the minimum and maximum values recorded within an adjustable time interval are available. Power Real time measurements of the total and phase power. Available at 2 different level of accuracy de- pending on the version, 1 % and 2%. In addition, the minimum and maximum values recorded within an adjustable time interval are available. Energy meters Measurements of the active, reactive and apparent energy totals, updated every minute. The measure- ments can be reset when needed. Frequency Measurement of line real time frequency, expressed in hertz. Peak Factor Real time measurements of the peak factors of the phase currents. The measurements are expressed as a ratio between the peak values and RMS values, for each single phase. Power Factor Power factor and real time measurements of the ra- tio between the total active power and total appar- ent power, expressed as Cos ϕ . In addition, the trip unit signals an alarm if the cos ϕ value drops below an adjustable threshold, settable via Ekip Connect software (from 0.5 to 0.95).
Datalogger This function allows the data related to a trigger event to be recorded. These data are: • Analog measurements: phase currents and phase-to-phase voltages • Digital events: protection alarms, circuit- breaker status signals, tripping of protections. When the datalogger is activated, the trip unit con- tinuously acquires data by filling and emptying an internal register. If a trigger event occurs, the trip unit inhibits acquisition (either immediately or with an adjustable time-lag) and stores the data, which is available for downloading. Network Analyzer This function fully evaluates the quality of the network. It is possible to set the controls to long cycle voltage and current in order to analyze the system functionality. Voltages and currents are monitored to find: • The sequence of voltages • Short term voltage drops or interruptions • Short duration voltage increases • Slow voltage drops • Slow voltage increases • Unbalances between the voltages • Harmonic distortion of voltages and currents. Waveforms A selected quantity can be represented as a wave- form and acquired at the moment of selection. The phase current and phase-to-phase voltage can be displayed. Harmonics A representation in the form of a histogram of the measurements of the harmonics that make up the waveform, and related to the frequency set.
