Test Sets For Transformer Industries
Contemporary Test Sets For Transformer Industries are developed to recognize the potentially disastrous current transformer errors. They prevent the primary current from overpowering insulation and short circuits. They are used for developing a testing and maintenance plan for addressing the errors before any failure to save money and time. With these powerful test sets, they are sure to perform saturation testing to test the knee point of a signal by comparing primary and secondary windings.

Potential Meters
Potential meters are basically electrometers which have extremely high input resistances in order to keep the feeding reference electrode free of load. This is necessary to maintain the true potential. pH - meters can be used as potential meters when fast reading is not required, because common pH meters are very slow. When the potential answer to current pulses is to be followed, potential meters are essential.
