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.

Zeta Potential Analyzers

Brookhaven Instruments Corporation
Almost all particulate or macroscopic materials in contact with a liquid acquire an electronic charge on their surfaces. Zeta potential is an important and useful indicator of this charge which can be used to predict and control the stability of colloidal suspensions or emulsions, for example. The greater the zeta potential the more likely the suspension is to be stable because the charged particles repel one another and thus overcome the natural tendency to aggregate. The measurement of zeta potential is often the key to understanding dispersion and aggregation processes in applications as diverse as water purification, ceramic slip casting and the formulation of paints, inks and cosmetic
