We are manufacturer and exporter of 3 phase power analyzer. PA700TFT series Power Analyzer has given revolution in testing of distribution and power transformer with the advanced feature of hysteresis (B/H) analysis. Core loss & winding loss measurement is important in transformer testing.

In conventional method, power Analyzer used with digital oscilloscope and phase converter to calculate knee value and saturation point of core. 3 phase power analyzer PA700TFT eliminate the requirement of multiple equipment and made the testing more easy by inbuilt hysteresis measurement mode. Which plot live hysteresis curve, so derivation of knee and saturation value is easy.

PA700TFT is multi-range power Analyzer with basic 0.05% R+R accuracy. 8 range of voltage, 8 range of current and total 64 range of power and power factor gives more accurate result. The gap less four-quadrant power measurement technique gives better accuracy at distorted waveforms or AC drive (VFD) operated power supply.

Any distortion in line power directly reflect on the measurement, 3 phase power analyzer PA700TFT has waveform display mode which gives d(y) / d(t) of line voltage and current. In addition, there is facility of zoom in and zoom out to get precise analysis.

3 phase power analyzer PA700TFT provides facility to selection speed of measurement by keypad. It play big role during setting test voltage and current in transformer testing. User can set fast speed mode during setting of test voltage and current and then accurate mode during fine measurement. It saves time in make testing easy.

Measuring system
3 phase power analyzer PA700TFT power analyzers accurately measure current and voltage and calculate power and calculate other derived, values from these high-precision measurements. Accuracy is not affected by either the waveform shape or frequency over a wide range. Phase shift accuracy is maintained due to the input channel design. Harmonics are calculated up to 64th on line frequency. The DSO function represents measured input parameters as waveforms. Voltage and current can be measured directly via the instrument’s integrated voltage dividers and current transformer. It is also possible to connect external voltage dividers as well as current transformer or current probes for specific applications.
