1. The instrument test has a total of YN winding three-phase test, YN winding three-phase phase-by-phase test, low-voltage winding magnetization method test of iron-core five-column low-voltage angular transformer, low-voltage winding phase selection test and general four-terminal method of ironcore three-column low-voltage angular transformer.
2. Press the method button to select different test methods and test the current.
3. The instrument repeats the test of current and potential, and the LCD screen shows the resistance value of the repeated test, if the repeated test results are consistent, the instrument is working normally, and the test value should be checked whether the wiring is correct when the error is relatively large.
4. After the end of the test, press the reset button to disconnect the charging circuit, the instrument is designed with a fast discharge circuit to release the energy stored in the winding, press the reset button after the buzzer sounds on behalf of the instrument working in the discharge state, the clock starts to discharge the timer, and the LCD screen displays the discharge voltage values. The buzzer stops on behalf of the end of the discharge, and the LCD screen displays the measured data from the beginning, at this time, you can remove the test line or select the current from the beginning, test the method, and test the tap position, or you can view the measured data of each tap by pressing the → and ←.

Schneider inverter frequently asked questions
1. Schneider inverter uses analog output port to indicate the motor frequency, when the motor frequency is 50Hz, why is the output only 16mA?
Answer: Because of the large output frequency parameter "TFR" of the inverter, the factory default value is 60Hz. So when the inverter output is 50Hz, the analog output is ...

Four-pole switches need a scene – Schneider
(1) It is necessary to choose a four-pole switch:
For the sake of repair safety: in the TT grounding system, the total equipotential bonding is done on the user side, but because the total equipotential bonding at this moment does not include the neutral wire, the line fault (for example: a phase wire grounding) occurs on the grounding electrode on the power supply side.
