Maintenance of the
D
evice
Turn off the energy of device and disconnect it from the connections. Clean the body of
the device with a slightly damp or dry cloth. Do not use conductive or other chemicals that
may damage the device as a cleaning materials. After the device is cleaned, make
connections and make sure that the device is working by energizing the device.
Points to Consider in Current Transformer Selection and Connection
Be careful about the value of the current transformer to be more than the maximum
current which could be/is
attracted from the system.
It is recommended that class of the current transformers (it can be also mentioned
class, klas, kl, cl ) should be 0,5 which will be used at the compensations.
Only X5A current transformers can be connected to the RGT-
12SVC
.
Be careful about the absence of any load before the current transformers. Otherwise
there can be differences between reactive and counter.
Current transformer outputs and phase inputs must be in the same order. Connect the
k-l terminals of the current transformer connected to the L1 phase to the k1-l1
terminals, the k-l terminals of the current transformer connected to the L2 phase to the
k2-l2 terminals and the k-l terminals of the current transformer connected to the L3
phase to the k3-l3 terminals.
While connecting output of the current transformer terminals in order to avoid
confusion, use different coloured cable for each phase or number the cables.
Pass the cables which is connected to the output of the current transformer far from the
high voltage line.
It is advised that the cables to be used which are connected to current transformer
should be minimum 1.5 mm2. It is also recommended that the cables should be
thickened as the distance increase.
In order to avoid shake at the current transformers, fix to the bus, cables or rail.
The cable distance connected to the current transformer output ends should not be kept long.
Otherwise there may be errors in the measurements.
Cable connected to current transformer output ends, one piece should be. Otherwise,
measurements may have errors and current transformer testing may not be possible.

Three-phase capacitor equivalent to 1/40 of current transformer ratio must be connected in
the first three steps for current transformer test to be performed. Also, the current
transformer connected to the device and the phase order of the voltages must be the same.
Otherwise, the device will give phase inverse or step low warning. After fixing the connection
errors according to the warnings, you can start the device setup again.

the UP and DOWN buttons and then
press the SET button to save.
The device will automatically start
Current Transformer Test operation.
In case of any problems in the
connections, the device will give a warning
and will not accept the connection.
According to the warnings, connection
errors after correcting, you can start
current transformer test again.
