Triple Frequency Test Transformer - Yangzhou Darui
Darui Electric recommends for you
Purpose
Triple Frequency Test TransformerSBF adopts a three-core five-column structure, theiron coreworkingmagnetic flux densityis selected above the saturation magnetic density, so that the open-delta connectedsecondary windingthe vector sum of thefundamental waveelectromotive force (positive sequence vector) is 0, while the open ends should output the same phase 150Hzthirdharmonic (zero sequence)
Features
Simple operation, reliable performance, can well meet thetransformer, instrument transformer induced overvoltage test needs
Working Principle
Using power electronics technology, the internal core part uses a frequency conversion regulator. Parameter presetting, protection setting, frequency selection, voltage regulation control, etc. Adopting touch operation mode, can preset 50Hz, 100Hz, 150Hz, 200Hz test frequency (optional), touch mode to adjust voltage (step size can be adjusted in real time, select 1V, 2V, 5V, 10V), can realize the multi-frequency test voltage output of this device.
3. Simple operation and wiring, greatly reduces the requirements for on-site test power supply capacity
