Measurement Description
Int Side Voltage
(2)
Voltage measured on internal sockets, given in Volts.
• .... = measurement less than 1 VAC
Ext Side Frequency
(1)
Frequency measured by Ekip Synchrocheck
• --- = measurement not available (example: because synchronism function is
disabled, or operation with dead busbar, or frequencies outside measuring range
limits)
Int Side Frequency
(2)
Frequency measured on internal sockets
• --- = measurement not available (example: because synchronism function is
disabled, or operation with dead busbar, or frequencies outside measuring range
limits)
Phase Difference
(1)
Phase difference between voltages, given in degrees
• --- = measurement not available (example: because synchronism function is
disabled, or operation with dead busbar, or frequencies outside measuring range
limits)
Auto detection
• Busbar active = with automatic detection of operating mode and operation with
active busbar, or with synchronism function not enabled
• Dead bar = with automatic detection of operating mode and operation with dead
busbar
• --- = Measurement not available (example: owing to manual detection of
operating mode)
Voltage relation
• Vint ≤ Vext = Internal voltage the same as external voltage or lower
• Vin > Vext = Internal voltage higher than external voltage
• --- = Measurement not available (example: because the synchronism function is
disabled, or direct voltages or voltages lower than 1 V).
Frequency relation
• fint ≤ fext = Internal frequency the same as external frequency or lower
• fin > fext = Internal frequency higher than external frequency
• --- = Measurement not available (example: because synchronism function is
disabled, or operation with dead busbar, or frequencies outside measuring range
limits)
(1)
voltage difference measurement accuracy is ± 10% unless the parameter value is 0.02 Un, in which case
accuracy is ± 20%
(2)
the characteristics of the voltage and frequency measurements coincide with those given on the internal
sockets (page 97)
Summary page
The summary page is activated in the presence of the Ekip Synchrocheck module; access is obtained in the
same way as the other summary pages (page 27).
The measurements in this page are:
• V int: voltage read by Ekip Touch
• f int: frequency read by Ekip Touch
• ΔΔ: phase difference
• SYNC: status of synchronism
About
The About - Modules menu contains the specific menu of the module with the serial number and version of
the module itself.
Remote information
Certain additional information concerning the version and status of the module is available via the service
connector (via Ekip Connect) or by communication via system bus; the information includes: HW and Boot
version, CRC status (correctness of the SW in the module).
