Description
Activate (ON) or deactivate(OFF) the frequency control for synchronism
evaluation
Activate (ON) or deactivate (OFF) the phase control for synchronism
evaluation
Activate (YES) or deactivate (NO) the open switch status control for
synchronism evaluation
NOTE: fourth synchronism condition with busbar active;
second synchronism condition with dead busbar
With active busbar, minimum time within which the Delta Phase time has
to be fulfilled
The value is expressed in seconds, settable in a range:
100 ms .. 3 s with 10 ms step
NOTE: this is not a synchronism condition, but a parameter
that enables correct and incorrect combinations of the Delta
frequency and Delta Phase conditions to be made. Owing to
the worst-case latency, the time that elapses before the
synchronism is recognized may be greater than the set time
(circa 20 ms)
Description

OK = synchronism conditions fulfilled

Not OK = synchronism conditions not fulfilled or function disabled

OK = frequency synchronism condition fulfilled

Not OK = frequency synchronism condition not fulfilled or synchronism function
disabled or frequencies outside measurement range

--- = Synchronism condition for frequencies is not available (e.g.: for operation
with dead busbar)

OK = Voltage synchronism conditions fulfilled

Not OK = Voltage synchronism conditions not fulfilled or function disabled

OK = Phase-difference synchronism condition fulfilled

Not OK = Phase-difference synchronism condition not fulfilled or synchronism
function disabled or frequencies outside measurement range

--- = Phase-difference synchronism condition is not available (e.g.: for operation
with dead busbar)
Voltage measured by Ekip Synchrocheck, expressed in Volt

.... = DC measurement DC or less than 1 VAC
(1)

--- = measurement not available (e.g.: because synchronism function disabled)
Voltage measured on the inside outlets, expressed in Volt.

(2)
.... = measurement less than 1 VAC
Frequency measured by Ekip Synchrocheck

--- = measurement not available (e.g.: because of disabled synchronism or
(1)
operation with dead busbar or frequencies outside measurement range)
Frequency measured on the inside outlets

--- = measurement not available (e.g.: because of disabled synchronism or
(2)
operation with dead busbar or frequencies outside measurement range)
Phase difference between voltages, expressed in degrees

--- = measurement not available (e.g.: because of disabled synchronism or
(1)
operation with dead busbar or frequencies outside measurement range)
