Parallel Capacitance Measurements. The relation between parallel and series capacitance measurements
is:
The following graph illustrates the relation between Cs and Cp. The graph is used to obtain a Cs value
for a capacitor by measuring the Cp and D values of the capacitor. To locate the Cs value, find the
measured D value along the horizontal axis of the graph. (The D reading from the Model 252 will be a
Dissipation Factor value not a Percent Dissipation value.) Move up the graph to the B curve and read
the corresponding value on the righthand vertical axis. Multiply the measured Cp value by this reading to
obtain the desired Cs value.
The A curve on the graph is used with the vertical axis in the same manner as described above. The A
curve and lefthand scale provide the Percent Difference between Cs and Cp.
