AC test by 3 Phase Relay Test Set

■ Interface Instruction

In the AC Test, each phase output is AC voltage. The amount of voltage, phase and the AC frequency can be adjusted to meet the various needs of the tests. In the test of relays and contacts protection, it can be recorded of action time, return time, action values, return values, etc.

In this menu you can test a variety of communication relays, phase, frequency relays, computer protection, and also the full group tests.

In this test, the variations are: Ua value, Ua phase; Ia value, Ia phase;

Ub value, Ub phase; Ib value, Ib phase;

Uc value, Uc phase; Ic value, Ic phase;

AC frequency.

Settings: the initial value of the variations, the step value of the variations (either positive or negative); when the variation need to adjust, mark" " to open .

Manual test / automated test: In the test, you can set the amount of change is manual or automatic.

After setting data and pressing "enter", please check the data and press "Start" to begin the test. The device starts to output, and the screen will pop up the contact state of the relay.

Manual test : use "▲", "▼" or rotary knob to control the amount of each step, observe actions on the display , it will show the action time, return time, and the RMS and phase angle of the output (Ua, Ub, Uc, Ia, Ib, Ic).

Automatic test : pressing "▲" or "▼" or "forward", "reverse", test will be again until the next position remain at that position to wait. This can be repeated continuously in all directions by the automatic test, determination of the action value, return value and so on.

● Digital Input: In the test, you can access any of the contact input terminals.

● Digital Output: By the two output lines, one is tracking the course, the trial press "start" when closed, the test "stop" when disconnected; The other way is tracking changes in the test data, which is changed after pressing "▲" or "▼" button, and disconnected when "stop".

● Data recording areas: when protection or return acts, in addition to record operating time and returning time, the lower part of the tester followed by action, amplitude and phase of Ua, Ub, Uc, Ia, Ib, Ic. The first line is the action value, the second line is the action phase, the third line is return value, and the fourth line is the return phase.

● Combined output: voltage and current can be combined with different capacity: AC voltage output of each phase is 120V. When a higher output voltage is needed, these two channels can be used together. AC current output is 40A per phase. When you need a larger output current, you can combine two or three channels, but pay attention to each phase at the same phase angle.

Attention：

1. When outputting a larger current, please use the shorter, thicker wire to reduce the circuit resistor.

2. Do not stay a long time in the large current output state, in order to avoid damage to the instruments and test equipment.

3. When doing the time test of the relay, the ‘Manual Operation’ testing mode should be selected due to normal action time may be longer.

■ Test guide

Testing action current, return current and action time, return time of AC relay.

Connect the IA and IN respectively to the operating coils of the test relay, the relay contacts connect to the A and + COM. Set the A-phase current from 8A on, the increasing step length is 0.1A, the test mode is set to automatic, then press "OK" and check the wiring and parameters, if correct, press "Start ", then the output of the relay current is 8A and increases by 0.1A/0.3s.

It can be seen from the display of the RMS current and relay contact status, after the tester output value that remain unchanged for the action, showing the operating time and the action of the output’s RMS and phase, from left to right for the UA, UB, UC, IA, IB, IC, the first line is RMS, the second line is phase; then rotate the mouse to the left (or click the "▼"), the tester output decreases when the contacts return, and the output retains, show the return time and return value(the third line is RMS, the fourth line is phase), testing wait for appointed operation or test stops. See the picture following.

Action current is 10A, the return value is 8A, operating time is 110ms, and the return time is 80ms.

DC test by 3 Phase Relay Test Set

Interface Instruction

In the DC Test, each phase output DC voltage. The amount of voltage, and the DC frequency can be adjusted to meet the various needs of the tests. In the test of contacts in relays and protection ,it can be recorded of action time, return time, action values, return values, etc. Test method is similar as AC test.

The test menu can test a variety of relays, such as DC, time, signal relays, reclosing relays and so on.

In this test, the variations are: Ua value, Ub value, Uc value ;

la value, Ib value, Ic value;

Settings: the initial value of the variation, the variation of the step (either positive or negative); when the variation need to adjust, mark " " opened.

Manual test / automated test: In the test, you can set the amount of change is manual or automatic.

After setting of data, press "confirm", then check the data and press "Start" to begin the experiment. The device starts to output, and the screen will pop up the contact state of the relay.

Manual test : using "▲", "▼" or rotary knob to control the amount of each step, observe actions on the display , it will show the action time, return time, and the RMS and phase angle of the output (Ua, Ub, Uc, Ia, Ib, Ic).

Automatic test : pressing "▲" or "▼" or "forward", "reverse", test will be again until the next position remain at that position to wait. This can be repeated continuously in all directions by the automatic test, determination of the action value, return value and so on.

● Digital Input: In the test, you can access any of the contact input terminals.

● Digital Output: By the two output lines, one is tracking the course, the trial press "start" when closed, the test "stops" when disconnected; The other way is tracking changes in the test data, which is changed after pressing button "▲" or "▼", and disconnected when "stop".

● Data recording areas: when protection or return acts, in addition to record action time and return time, the lower part of the tester followed by action, amplitude and phase of Ua, Ub, Uc, Ia, Ib, Ic. The first line is the action value, the second line is the action phase, the third line is return value, and the fourth line is the return phase.

● Combined output : DC voltage output of each phase is ±160V. When a higher output voltage is needed, these two channels can be used together.

Attention：

1.When doing the time test of the relay, the automatic change interval is 0.3s, if normal action time is longer, the ‘Manual Operation’ testing mode should be selected.

2.When doing signal relay or polarized relay trial that has very small current (less than 20mA) , due to the large relay coil resistance (several hundred to several thousａnd ohm), it can not be used to test by current-output but voltage-output, you can get the action circuit using the action voltage divided by the coil resistant which measured by mutimeter.
