General description
The 3TX20 is designed for use in brushless generators and can be used as a cost effective
universal replacement for a great variety original manufacturers AVR’s.
The 3TX20 can be used for parallel operation with other generators that also control voltage droop
by means of Quadrature Droop Compensation (QDC).
Parallel operation is possible with an additional droop CT.
Installation, maintenance and adjustment don’t require special application software.
The AVR is protected from the environment by a PUR coating.

Tips and Suggestions I
Precautions for large, slow running generators
In general large (>1000kVA), slow running (<900RPM) generators tend to have more inductive exciter
field windings. When the 3TX20 is used to control such a generator, the switched excitation current in
combination with the increased inductivity can cause voltage spikes on the field excitation output.
This can cause excessive AVR heating and damage to the AVR’s output stage. To reduce voltage
spikes it is recommended to fit RC-snubber in parallel and as close as possible to the exciter field.
Generator insulation- / polarization index test
As a rule of thumb the testing voltage used during an insulation test is two times the nominal voltage of
the winding under test. This exceeds the AVR ratings and may cause permanent damage to the AVR.
Therefore the AVR must be disconnected completely from the generator. When performing an
insulation test on the generator rotor disconnect the rotating rectifiers and any other components from
the windings under test. This will prevent damage should the testing voltage exceed the rectifiers
blocking voltage.
Field flashing
In case of a self excited generator it could be that the residual voltage level is too low to build up.
Causes for a low residual voltage can be a prolonged period of stand still, excessive heating or
mechanical shock and vibration.
To restore the residual voltage the generator can be manual field flashed. In order to perform this safely
the AVR must be completely disconnected from the generator. Next a potential free voltage
(e.g. a 9V battery block) source is connected to the exciter field of the generator, while it’s rotating.
This will cause the generator voltage to rise and restore the residual voltage level.
If the residual voltage of the generator is permanently low, an automatic field flash unit can be used or a
potential free voltage source which is automatically switched off when the generator voltage is within
normal range. The generator voltage should not exceed nominal voltage when field flash is active, to
prevent damage to the AVR. When using “Automatic field flash” there should always be a rectifier
bridge in the output of the source/unit.

Phase loss protection
Default the phase loss protection is disabled.
Dip 4
The phaseloss protection validates the presence of all three generator phases on the sensing
terminals U, V and W . When one of the three phases is not sensed anymore for more than 300ms
the AVR decreases the generator voltage setpoint to +/- 40% of Unom. If the error condition is
relieved for 5s, the generator voltage is ramped up again to nominal voltage.

Fuse protection
When replacing the fuse, a 20A/500V slow type fuse with dimensions 10.3 x 38.1mm must be used.
To prevent consequential damage in case of an AVR or generator failure, the AVR supply is fused by
a 20A slow fuse.
Blowing the fuse will interrupt the field excitation output and causes the generator to de-excite.

General installation information
Absolute Maximum Ratings
- The Absolute Maximum Ratings are those limits for the device that, if exceeded, will likely damage the device. Exceeding the
absolute maximum ratings voids any warranty and/or guarantee.
Mounting
Mounting of the product should be done in such a way that:
-the absolute maximum ambient temperature rating of the product will never be exceeded.
-maximum cooling (direction of cooling ribs and direction of airflow) is achieved.
-Mounting no humid air can flow through the product or condensation occurs.
-dust or other materials or residue will not remain in or on the product.
-the maximum vibration is not exceeded.
-personal contact with persons is impossible.
Wiring
-Diameter size of the wiring should be enough to carry the expected current. Wire insulation should be enough to withstand
the expected operating voltages and temperatures.
-To improve EMC emission and immunity, care should be taken for the lay out of the wiring. This in respect to all wiring in the
installation.
-Keep current carrying wires as short as possible.
-Keep wires carrying a total sum of zero Ampere close to each other, or in one single cable, E.g. U, V, W, or X (+) and XX (-),
or Phase and neutral, or S and T.
-Avoid current carrying conductors next to sensing or control wiring. Especially current controlled by SCR’s or PWM controlled
transistors.
-If sensitive sensing signal cables need to be laid across distance along other cabling, shielded cable is preferred. Keep the
shield as long as possible and the wiring outside the shield as short as possible. Do not solder or shrink the shield to a
regular wire. Connect the original shield to ground at one side with an as large as possible contact surface.
Additional installation information
- When the product is supplied by means of a transformer, it should never be an auto-transformer. Auto-transformers react as
voltage sweep up coil and may cause high voltage peaks.
-Standard fit capacitors or over-voltage suppressers across X (+) and XX (-), or exciter field terminals inside the generator
should be removed.
-When the product is supplied by means of a transformer, it should be able to carry at least the maximum expected current.
Advisable is, to have a transformer which can carry twice the maximum expected current. Inductive loads make voltage sacks
and peeks into the secondary voltage of a transformer, from which the device may malfunction.
-It is not recommended to apply switches in dc outputs. It is preferred to use switches in the ac supply inputs of devices. In
case it is unavoidable to have switches in the dc output of a device, action must be taken to avoid over voltage damage to the
device due to contact arcing. Use a voltage suppressor across the output.
-It is not recommended to apply switches or fuses in the sensing lines. Defects can cause high voltage situations due to over-
excitation.
-When using a step down transformer in medium or high voltage generators, the transformer should be three phase (if three
phase sensing), and the transformer should be suitable for acting as a sensing transformer. If the transformer is unloaded,
connect a resistor to avoid voltage waveform distortion.
-The phase relation from the generator to the AVR is important. Also when voltage transformers and/ or current transformers
are installed.
-When using a step down or insulation transformer in the droop circuit, phase relation from the generator to the AVR is
important.
-CT’s wiring, connected to the AVR should never be grounded.
-Always disconnect electronic products, circuits and people before checking the insulation resistance (Megger check).
-Due to differences in generators impedance’s, EMC behavior is not predictable. Therefore the commissioner / installer should
be aware of proper and correct installation.
-Large, highly inductive, exciter stator windings can cause destructive high voltage peaks. Adding a resistor from 10 to 20
times the exciter stator field resistance reduces voltage spikes. If necessary filter can be fitted additionally. (e.g. snubber, RC-
network)
-Upon problems during commissioning, faulty behavior or defects in the generator, consult the fault finding manual at our web
site
-Some advises may be overdone or seem extraordinary, but since the electrical rules are the same everywhere, these advises
are given.
