Ⅰ.OUTLINE
Phase shifter is a new generation of portable electrical equipment which
is composed by transformer phase shifter, digital phase display, digital voltage
and current display, output voltage adjustment, fine-tune of phase shift and
power source modules and so on, this product combine the technology of
transformer phase shifter and digital measurement, with the advantages of
high precision for phase adjustment ,accurate and intuitive readings,
adjustable output voltage. The structure of this machine is solid and reliable,
sealed, and easy to carry or to use in the field and on site.
Ⅱ. APPLICATION AND APPLIED SCOPE
Phase shifter can reach any point of the lead or lag phase shift from 0 to
360 degrees.
The phase shifter transformer has three phases and three core
columns,with Y0 wiring way. Each phase has four equilateral windings, whith
are cross-connected with different angles to form a hexagon connected to the
diagonals. The hexagon has tewlve files, and each file has 30 degrees.Thus
we can do synchronous adjustment of three phases. The fine tune bases on
three coaxial autotransformers and capacitors, and the output phase in the
range of 0 to 360 can be adjusted simultaneousely to ensure the balance
output of three phases.

7
The phase shifter has the characteristics of easy operation, small size,
low noise and good output waveform, whith is able to meet the test and
calibration for high AC power and phase of single or three phases, phase and
other, and can also be used among test device of meter.

This phase shifter is designed amd maded by the theory of transformer
phase shift,and the fundamental theory is explained in the block diagram:
Ⅴ.HOW TO USE
(1)The panel diagrame and description of digital three-phase phase shifter
Panel：

A1. Phase shift display, Four figures display 0° ~ 360° phase angle.
A2. Load current display of output V phase, three and a half figures display.
A3. Voltage display of between output U, W phase, three and a half figures
display.
A4. Rough tune button，phase shift by the surface scale.
A5. Reset button of phase display. Press the key to display the phase angle.
A6. Latch button of phase display.With no change of phase, we can press the
key to lock the number.
A7. Power switch, this key can be pressed to put on or cut off the whole
internal power supply.
A8. Switch for the choice of output function. When it is turned to voltage
function, the machine gives the output of voltages of U,V,M phases which are
corresponding to the phase shift of input A,B,C source; and when turned to

10
current function, the machine gives the output of AC current range from 0~20
A, witch lead to the phase shift of iuput B source.
A9. Fine tune selection switch, choice of two range: -3°~18°, 12°~33°.
A10. Adjustment button of output voltage, and the outputs of U,V,W phase are
adjusted simultaneousely by this button.The voltage display gives the voltage
of U,W phase range from 0~380V.
A11. Fine tune button, combined with A9 it can achieve the function of phase
shift in 30°.
B1.Binding columns of input three phases and four wires.
B2.Ground column of the chassis.
B3.F1, F2, F3 buttons are respectively corresponding to the insurance block of
C, B, A phases.
B4. Binding columns of output three phases and four wires.
B5. F4, F5, F6 buttons are respectively corresponding to the insurance block
of W, V, U phases.
B6. Binding column of output current.
(2) How to use
1. Check B3, B5 of the panel to insure the fuse is intact.
2. Cut off the power button and turn the the output voltage button A10 to the
lowest,then connect the input source of three phases and four wires A, B, C, O
on the panel B1.
3. Connect the neccesary load for output voltage of U, V, W, N phases on the

11
panel B3. the load power can not exceed the maximum output power of the
machine.
4. Close the external blade, and turn on the machine power switch A7, the
displays of A1, A2, A3 also should be light.
5. Adjust the output voltage button A10 to the designed value after power on
for half a minute.Get the output voltage from U, V, M, N phases, among witch
A3 dispalys the voltage of U, W phases, A2 displays the load current of V
phase.
6. Adjust the rough tune button to the approximate designed phase shift angle,
then adjust the fine tune button A11 with the selection switch A9(when the
switch is up, adjust A11 clockwisely for one loop and the phase shift is 15° ；
when the switch is down, adjust A11 Counterclockwisely for one loop and the
phase shift is 15°).After adjustting A4 button,turn the selection swith A9 to the
top and turn the button A11 clockwisely, then the display of phase shift
increases.One scale of rough tune includes fine tune range from 0°~30°, and
the A1 displays the phase shift angle with the reset button A5.After adjusted to
the designed angle,press latch button A6 to lock the number of A1.Also, Press
A5 again to get a new phase shift angle.
Ⅵ.NOTES
1. It is not allowed to connect the output point N to input zero line.
2.The machine is on the work with strong power, so it is necessary that ground

12
column of the chassis to be grounded.
3.The maximum current of the fuse is 5A and as the short circuit and overload
protection it is necessary to comply the provision.
4. Minus the number of A2, A3 witch is get from the situation as output is zero
to resist the environment interference.
5. After turning on the power, if without any display, Cut off the power.firstly,
check the insurance and then check the external input of three phases and
four wires. If still with no display, please contact us.
6. The warranty of the product is one year. Among the warranty period it is
free to repair the machine because of quality and technical problems and we
provide preferential services caused by careless handling.
Ⅶ.MAINTENANCE
1. Verify the availability of the equipment
Observe the appearance of the instrument before use. After turning on
the power check the instrument display is showing completely or not. If the
instrument is not used for long time it is should also check whether the Binding
columns of output part are corroded or aging. Clear up before use timely.
Refer to "How to use" chapter when using it.
2. Equipment maintenance
After test, clear the wires connected among columns, then cut off the
power and disconnect the power plug , cover the chassis cover finally place

13
the equipment indoors in dry, clean, non-corrosive gas environment.
3. The way of replacing the fuse
The fuse and the power plug is connected so turn off the power before
replacing, then set aside the fuse box with a small flathead screwdriver.
