Measurement
Description
Module
• Ok = Synchronism conditions fulfilled
• Not Ok = Synchronism conditions not fulfilled or function disabled
Frequency
• Ok = Synchronism condition regarding frequencies fulfilled
• Not Ok = Synchronism condition regarding frequencies not fulfilled or synchronism
function disabled, or frequencies outside measuring range limits.
• --- = Synchronism condition regarding frequencies not available (example: for
operation with dead busbar)
Voltage
• Ok = Synchronism conditions regarding voltages fulfilled.
• Not Ok = Synchronism conditions regarding voltages not fulfilled or synchronism
function disabled
Phase
• Ok = Synchronism condition regarding phase difference fulfilled
• Not Ok = Synchronism condition regarding phase difference not fulfilled or
synchronism function disabled, or frequencies outside measuring range limits
• --- = Synchronism condition regarding phase difference not available (example: for
operation with dead busbar)
Ext Side Voltage
(1)
• Voltage measured by
Ekip Synchrocheck
given in Volts
• .... = measurement DC or less than 1 VAC
• --- = measurement not available (example: because synchronism function is
disabled)
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 109)
