Short circuit test instrument
DDT - 2 is a desktop coil, general electric motor short circuit test instrument, the instrument is suitable for various coils, small AC motor stator, rotor winding short circuit test, at the same time judgment and inspection of the DC motor armature winding short circuit test and rat cage. The quality of the instrument is also applicable to motor winding a closed loop (winding in delta connection, parallel branches etc.) under the condition of short circuit fault detection at the same time. Flexible application, can also check the winding connection.
The instrument test intensity can be adjusted continuously, the light emitting diode, clear and intuitive. And alarm device.
Two main features
1.: do not have high sensitivity probe and the tested workpiece surface with general 3~5mm apart can correctly display a turn over short circuit.
- high accuracy: accurate to each slot of the measured workpiece, and the number of turns of coil can be measured separately. With high contact resistance of interturn short circuit can be measured.
- high efficiency: the detection of a workpiece without short circuit, only a few seconds, safe and convenient.
- measuring range: instrument test intensity can be adjusted continuously, and an attenuator, the measured motor capacity is from hundreds of watts to several kilowatts can be combined, and the instrument is also provided with an oscilloscope interface.
