About RGT-MT
It is designed to reduce reactive (inductive and capacitive) power that comes from the
network and loads do not use. If the inductive reactive power is attracted from the network,
it interferes by attracting capacitor at the appropriate step. If capacitive reactive power is
attracted from the network, t interferes by attracting shunt reactor at the appropriate step.
Thus it endeavors to reduce the inductive/active and capacitive/active rates of the system.
It is designed to make more sensible compensation at the unbalanced inductive and
capacitive systems with RGT-MT18 TCR(SVC) step.
2
While making current transformer test and measurement of the step, be careful about
avoiding rapid load changing on the system as much as possible.
Compensation starts with the regulations of the load distribution of the Electrical
wiring in a balanced way that belongs to the system.
Connect three phase capacitor with high value to the first three step (C1, C2, C3) for the
current transformer test.
Do not define step number and capacitor values randomly where has rapid load changing
and where huge amount of load is distributed randomly.
You can get benefit from the examples which are in the Power Analysis, in order to
compensate more effectively to the unbalanced loads in the system.
While preparing compensation board be careful about that you should easily add new
steps for probable changings (load adding or excluding) that can occur subsequently.
It is advisable to add new steps at the same value for the lifespan of the commonly used
step's conductor and capacitor.
Matters to Be Considered In Compensation
Choose the automatic fuse current values used in steps according to the power of the
capacitor and reactor and point as connection removing member.
Use different automatic fuse for each feeding inductor of the step conductors.
Use compensation conductor sand discharge inductors at the steps.
Unique phase connection at the three phase systems is only appropriate for balanced
load attraction. Otherwise desired rates cannot be obtained.
Warnings
Use the device according to our instructions.
Avoid direct sun light in order not to harm the LCD screen.
Leave at least 10 cm of space behind the device after mounting.
Fix the device with apparatus which comes within the device by avoiding any kind of
shake on the front cover of the board.
Balance the inner and outer heat in the metal boards. Otherwise because of the
temperature difference that originates from the dampish surrounding, water droplets
occurs on the ceiling of the board and this situation is dangerous for the open connected
buses.
Keep the switch and circuit breaker close to the device and easily accessible by the
operator.
Mark the switch and circuit breaker as the connection tripping element for the device.
There must be no electricity in the connection cables when assembling.
Screened and twisted cord cables should be used on the input and output lines without
connection to the Mains (network). These cables should not pass near high-Voltage lines
and devices.
Do not touch the touchscreen with a hard, sharp object.
Maintenance of the Device
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.

Point to Pay Attention About The Choice And Connection of the Current
Transformers
How to Connect the NTC to Inside of the Panel Temperature?
In order to measure the surrounding temperature of the panel,
NTC terminal will be attached which comes within the device.
NTC's one terminal will be attached to the RS485 connection's
GND, the other terminal will be connected to the NTC. When the
connection accomplished, panel heat value is seen on the screen.
When the connection disconnected or reach to the -40, ''NC'' sign
is seen on the screen.
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-MT18.
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.

Indicates that the system is fed from the network or generator.
When voltage (220V) is applied to the generator input, the system
is supplied from the generator. If there is no voltage at the
