2. Working Principle of Electrical Stability Tester DWY-2
The measurement of electrical stability (ES) is to apply a sinusoidal telecomunication signal with gradually rising voltage to a pair of parallel plate electrodes immersed in drilling fluid. The generated current is very weak until it reaches a critical voltage, and then the current intensity rises sharply. This critical voltage is called the ES value of the oil-based drilling fluid and is defined as the peak voltage measured at the current intensity of 61ua, unit is volts.
